It serves much of the population of northern Afghanistan. In 2013, a sixty million euro terminal was added to the airport while the older terminal

172-645: A republic of the Soviet Union . It declared independence as the Republic of Uzbekistan in 1991. Uzbekistan is a secular state , with a semi-presidential constitutional government. Uzbekistan comprises 12 regions (vilayats), Tashkent City, and one autonomous republic, Karakalpakstan . While non-governmental organisations have defined Uzbekistan as "an authoritarian state with limited civil rights ", significant reforms under Uzbekistan's second president, Shavkat Mirziyoyev , have been made following

258-481: A catastrophic scenario with the agricultural industry being the main contributor to the pollution and devastation of both air and water in the country. The Aral Sea was once the fourth-largest inland sea on Earth, humidifying the surrounding air and irrigating the arid land. Since the 1960s, when the overuse of the Aral Sea water began, it has shrunk to about 10% of its former area and divided into parts, with only

344-409: A defined barometric pressure . Generally, the pressure used to set the altimeter is the barometric pressure that would exist at MSL in the region being flown over. This pressure is referred to as either QNH or "altimeter" and is transmitted to the pilot by radio from air traffic control (ATC) or an automatic terminal information service (ATIS). Since the terrain elevation is also referenced to MSL,

430-432: A few metres, in timeframes ranging from minutes to months: Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities

It served all ISAF personnel, including American and Afghan Armed Forces . Work on a new international terminal began in 2010 and was completed in 2013. A special inauguration ceremony was held in June 2013, which was attended by then-German Foreign Minister Guido Westerwelle , Afghanistan's Transport and Aviation Minister Daoud Ali Najafi , Balkh's Governor Atta Muhammad Nur and some parliamentarians. After

774-717: A part of the Persian empire of the day. Before the arrival of the Russians, present-day Uzbekistan was divided between the Emirate of Bukhara and the khanates of Khiva and Kokand . In the 19th century, the Russian Empire began to expand and spread into Central Asia . There were 210,306 Russians living in Uzbekistan in 1912. The " Great Game " period is generally regarded as running from approximately 1813 to

860-486: A quarter of its military budget), the government of Uzbekistan has recently restricted American military use of the airbase at Karshi-Khanabad for air operations in neighbouring Afghanistan. Uzbekistan was an active supporter of U.S. efforts against worldwide terrorism. The relationship between Uzbekistan and the United States began to deteriorate after the so-called " colour revolutions " in Georgia and Ukraine (and to

946-438: A reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land surveying . An alternative is to base height measurements on a reference ellipsoid approximating the entire Earth, which is what systems such as GPS do. In aviation, the reference ellipsoid known as WGS84

1032-457: A rich Perso-Islamic culture. During his reign and the reigns of his immediate descendants, a wide range of religious and palatial construction masterpieces were undertaken in Samarkand and other population centres. Tamerlane also established an exchange of medical discoveries and patronised physicians, scientists and artists from the neighbouring regions such as India; His grandson Ulugh Beg

1118-407: A sharp reduction in greenhouse gas emissions, this may increase to hundreds of millions in the latter decades of the century. Local factors like tidal range or land subsidence will greatly affect the severity of impacts. For instance, sea level rise in the United States is likely to be two to three times greater than the global average by the end of the century. Yet, of the 20 countries with

1204-417: Is an average surface level of one or more among Earth 's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datum  – a standardised geodetic datum  – that is used, for example, as a chart datum in cartography and marine navigation , or, in aviation, as the standard sea level at which atmospheric pressure

1290-488: Is because the sea is in constant motion, affected by the tides, wind , atmospheric pressure, local gravitational differences, temperature, salinity , and so forth. The mean sea level at a particular location may be calculated over an extended time period and used as a datum . For example, hourly measurements may be averaged over a full Metonic 19-year lunar cycle to determine the mean sea level at an official tide gauge . Still-water level or still-water sea level (SWL)

1376-427: Is due to change in either the volume of water in the world's oceans or the volume of the oceanic basins . Two major mechanisms are currently causing eustatic sea level rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the oceans. Second, as ocean temperatures rise, the warmer water expands. Many factors can produce short-term changes in sea level, typically within

1462-483: Is increasingly used to define heights; however, differences up to 100 metres (328 feet) exist between this ellipsoid height and local mean sea level. Another alternative is to use a geoid -based vertical datum such as NAVD88 and the global EGM96 (part of WGS84). Details vary in different countries. When referring to geographic features such as mountains, on a topographic map variations in elevation are shown by contour lines . A mountain's highest point or summit

1548-512: Is measured to calibrate altitude and, consequently, aircraft flight levels . A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales . Current sea level rise is mainly caused by human-induced climate change . When temperatures rise, mountain glaciers and polar ice sheets melt, increasing

1634-536: Is now used for domestic flights. Though originally constructed with 2 parallel runways, the airport's northernmost runway has since been converted into a taxiway, making it one of the largest airports in Afghanistan . The Mazar-i-Sharif rail terminal is located to the east of the airport, which is connected to the Hairatan border town in the north. The Ministry of Defense also has a military base adjacent to

1720-600: Is opposed to reintegration and withdrew from the CIS collective security arrangement in 1999. Since that time, Uzbekistan has participated in the CIS peacekeeping force in Tajikistan and in UN-organized groups to help resolve the Tajikistan and Afghanistan conflicts, both of which it sees as posing threats to its own stability. Previously close to Washington (which gave Uzbekistan half a billion dollars in aid in 2004, about

1806-450: Is the level of the sea with motions such as wind waves averaged out. Then MSL implies the SWL further averaged over a period of time such that changes due to, e.g., the tides , also have zero mean. Global MSL refers to a spatial average over the entire ocean area, typically using large sets of tide gauges and/or satellite measurements. One often measures the values of MSL with respect to

1892-727: Is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . Sea level rise lags behind changes in the Earth 's temperature by many decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. What happens after that depends on human greenhouse gas emissions . If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ft) from now and approximately 60 cm (2 ft) from

1978-531: Is typically illustrated with the AMSL height in metres, feet or both. In unusual cases where a land location is below sea level, such as Death Valley, California , the elevation AMSL is negative. It is often necessary to compare the local height of the mean sea surface with a "level" reference surface, or geodetic datum, called the geoid . In the absence of external forces, the local mean sea level would coincide with this geoid surface, being an equipotential surface of

In the long run, sea level rise would amount to 2–3 m (7–10 ft) over the next 2000 years if warming stays to its current 1.5 °C (2.7 °F) over the pre-industrial past. It would be 19–22 metres (62–72 ft) if warming peaks at 5 °C (9.0 °F). Rising seas affect every coastal and island population on Earth. This can be through flooding, higher storm surges , king tides , and tsunamis . There are many knock-on effects. They lead to loss of coastal ecosystems like mangroves . Crop yields may reduce because of increasing salt levels in irrigation water. Damage to ports disrupts sea trade. The sea level rise projected by 2050 will expose places currently inhabited by tens of millions of people to annual flooding. Without

6020-425: The land; hence a change in relative MSL or ( relative sea level ) can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates, or both. In the UK, the ordnance datum (the 0 metres height on UK maps) is the mean sea level measured at Newlyn in Cornwall between 1915 and 1921. Before 1921, the vertical datum was MSL at the Victoria Dock, Liverpool . Since

6106-481: The melting of ice sheets at the end of the last ice age . The weight of the ice sheet depresses the underlying land, and when the ice melts away the land slowly rebounds . Changes in ground-based ice volume also affect local and regional sea levels by the readjustment of the geoid and true polar wander . Atmospheric pressure , ocean currents and local ocean temperature changes can affect LMSL as well. Eustatic sea level change (global as opposed to local change)

6192-433: The pilot can estimate height above ground by subtracting the terrain altitude from the altimeter reading. Aviation charts are divided into boxes and the maximum terrain altitude from MSL in each box is clearly indicated. Once above the transition altitude, the altimeter is set to the international standard atmosphere (ISA) pressure at MSL which is 1013.25 hPa or 29.92 inHg. Uzbekistan Uzbekistan , officially

6278-545: The princes of various tribal groups competed for influence. One tribal chieftain, Timur (Tamerlane), emerged from these struggles in the 1380s as the dominant force in Transoxiana. Although he was not a descendant of Genghis Khan, Timur became the de facto ruler of Transoxiana and proceeded to conquer all of western Central Asia, Iran , the Caucasus , Mesopotamia , Asia Minor , and the southern steppe region north of

6364-485: The province of Transoxiana , and further east in what is today Xinjiang , the Sogdian intermediaries became the wealthiest of these merchants. As a result of this trade on what became known as the Silk Road , Bukhara and Samarkand eventually became extremely wealthy cities, and at times Transoxiana (Mawarannahr) was one of the most influential and powerful provinces of antiquity. In 327 BC, Macedonian ruler Alexander

6450-586: The region of Uzbekistan was ruled by the Hephthalites and Sassanid Empires, as well as by other empires, for example, those formed by the Turkic Gokturk peoples. The Muslim conquests from the seventh century onward saw the Arabs bring Islam to Uzbekistan. In the same period, Islam began to take root among the nomadic Turkic peoples . In the eighth century, Transoxiana, the territory between

6536-549: The region served as the birthplace, home, and capital of Tamerlane . Under Tamerlane, the region was a part of the Timurid Empire which extended from the Black Sea to the Arabian Sea , and to just outside of Delhi, India The first people known to have inhabited Central Asia were Scythians who came from the northern grasslands of what is now Uzbekistan, sometime in the first millennium BC; when these nomads settled in

6622-531: The region they built an extensive irrigation system along the rivers. At this time, cities such as Bukhoro ( Bukhara ) and Samarqand ( Samarkand ) emerged as centres of government and high culture. By the fifth century BC, the Bactrian , Sogdian , and Tokharian states dominated the region. As East Asia began to develop its silk trade with the West, Using an extensive network of cities and rural settlements in

6708-531: The south of the country. Uzbekistan has also been home to seismic activity, as evidenced by the 1902 Andijan earthquake , 2011 Fergana Valley earthquake , and 1966 Tashkent earthquake . A dam collapse at Sardoba Reservoir in May 2020 flooded 35,000 hectares of land. Six people died and 111,000 evacuated with recovery estimates over 1.5 trillion som. The devastation extended into areas inside neighbouring Kazakhstan . After Uzbekistan declared independence from

6794-547: The southern part of the narrow western lobe of the South Aral Sea remaining permanently in Uzbekistan. Much of the water was and continues to be used for the irrigation of cotton fields , a crop requiring a large amount of water to grow. Due to the Aral Sea loss, high salinity and contamination of the soil with heavy elements are especially widespread in Karakalpakstan , the region of Uzbekistan adjacent to

6880-408: The southwest, Tajikistan to the southeast, and Kyrgyzstan to the northeast, Uzbekistan is one of the largest Central Asian states and the only Central Asian state to border all the other four. Uzbekistan also shares a short border (less than 150 km or 93 mi) with Afghanistan to the south. Uzbekistan is a hot, dry, landlocked country . It is one of two doubly landlocked countries in

6966-455: The times of the Russian Empire , in Russia and its other former parts, now independent states, the sea level is measured from the zero level of Kronstadt Sea-Gauge. In Hong Kong, "mPD" is a surveying term meaning "metres above Principal Datum" and refers to height of 0.146 m (5.7 in) above chart datum and 1.304 m (4 ft 3.3 in) below the average sea level. In France,

7052-551: The vote. Most international observers refused to participate in the process and did not recognise the results, dismissing them as not meeting basic standards. The 2002 referendum also included a plan for a bicameral parliament consisting of a lower house (the Oliy Majlis) and an upper house (Senate). Members of the lower house are to be "full-time" legislators. Elections for the new bicameral parliament took place on 26 December. Following Islam Karimov's death on 2 September 2016,

7138-411: The weight of cooling volcanos. The subsidence of land due to the withdrawal of groundwater is another isostatic cause of relative sea level rise. On planets that lack a liquid ocean, planetologists can calculate a "mean altitude" by averaging the heights of all points on the surface. This altitude, sometimes referred to as a "sea level" or zero-level elevation , serves equivalently as a reference for

7224-445: The world - that is, a landlocked country completely surrounded by other landlocked countries. The second doubly landlocked country is Liechtenstein . In addition, due to its location within a series of endorheic basins , none of its rivers lead to the sea. Less than 10% of its territory is intensively cultivated irrigated land in river valleys and oases. The Aral Sea , which has been largely desiccated by cotton production established in

7310-619: Was one of the world's first great astronomers. It was during the Timurid dynasty that Turkic, in the form of the Chaghatai dialect, became a literary language in its own right in Transoxiana, although the Timurids were Persianate in culture. The greatest Chaghataid writer, Ali-Shir Nava'i , was active in the city of Herat (now in northwestern Afghanistan) in the second half of the 15th century. The Timurid state quickly split in half after

7396-408: Was replaced by his long-time Prime Minister , Shavkat Mirziyoyev , on 14 December of the same year. On 6 November 2021, Mirziyoyev was sworn into his second term in office, after gaining a landslide victory in presidential election. Uzbekistan has an area of 448,978 square kilometres (173,351 sq mi). It is the 56th largest country in the world by area and the 40th by population. Among
