Dimitar Ouzounov (Bulgarian language, Bulgarian: Димитър Узунов) is a Bulgarian–American Geophysics, geophysicist, research scientist, academic, and author. He is a research professor of geophysics at Institute for Earth, Computing, Human and Observing (Institute for ECHO), Chapman University. Ouzounov has worked in Interdisciplinarity, cross-disciplinary problem-solving related to Earth system science, Geophysics, and Natural Hazards, with a focus on Geological hazard, geohazards, earthquake science, geospace observations, and the interaction between geospheres. In particular, he has researched using near-space Earth observations to study Geodynamics, geodynamic processes and contributed to the validation of a new geophysical theory related to earthquake processes.

Bulgaria
Bulgaria, officially the Republic of Bulgaria, is a country in Southeast Europe. It is situated on the eastern portion of the Balkans directly south of the Danube river and west of the Black Sea. Bulgaria is bordered by Greece and Turkey to the south, Serbia and North Macedonia to the west, and Romania to the north. It covers a territory of and is the tenth largest within the European Union and the List of European countries by area, sixteenth-largest country in Europe by area. Sofia is the nation's capital and List of cities and towns in Bulgaria, largest city; other major cities include Burgas, Plovdiv, and Varna, Bulgaria, Varna. One of the earliest societies in the lands of modern-day Bulgaria was the Karanovo culture (6,500 BC). In the 6th to 3rd century BC, the region was a battleground for ancient Thracians, Persians, Celts and Ancient Macedonians, Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Environment
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aqua (satellite)
Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the Precipitation (meteorology), precipitation, evaporation, and Water cycle, cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (satellite), Terra (launched 1999) and followed by Aura (satellite), Aura (launched 2004). The name "Aqua" comes from the Latin word for water. The satellite was launched from Vandenberg Air Force Base on May 4, 2002, aboard a Delta II Launch vehicle, rocket. Aqua operated in a Sun-synchronous orbit as the third in the satellite formation called the "A-train (satellite constellation), A Train" with several other satellites (OCO-2, the Japanese GCOM, GCOM W1, PARASOL, CALIPSO, CloudSat, and Aura (satellite), Aura) for most of its first 20 years; but in January 2022 Aqua left the A-Train (as Cloud Sat, CALIPSO and PARASOL had already done) when, due to its fuel limitations, it transitioned to a free-drift mode, w ...

Terra (satellite)
Terra (EOS AM-1) is a multi-national scientific research satellite operated by NASA in a Sun-synchronous orbit around the Earth. It takes simultaneous measurements of Earth's atmosphere, land, and water to understand how Earth is changing and to identify the consequences for life on Earth. It is the flagship of the Earth Observing System (EOS) and the first satellite of the system which was followed by Aqua (launched in 2002) and Aura (launched in 2004). Terra was launched in 1999. The name "Terra" comes from the Latin word for Earth. A naming contest was held by NASA among U.S. high school students. The winning essay was submitted by Sasha Jones of Brentwood, Missouri. The identifier "AM-1" refers to its orbit, passing over the equator in the morning. Launch The satellite was launched from Vandenberg Air Force Base on December 18th, 1999, aboard an Atlas IIAS vehicle and began collecting data on February 24th, 2000. It was placed into a near-polar, sun-synchrono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moderate Resolution Imaging Spectroradiometer
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Geocentric orbit, Earth orbit: one on board the Terra (satellite), Terra (Earth Observing System, EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (satellite), Aqua (EOS PM) satellite, launched in 2002. Since 2011, MODIS operations have been supplemented by VIIRS sensors, such as the one aboard Suomi NPP. The systems often conduct similar operations due to their similar designs and orbits (with VIIRS data systems deisgned to be compatible with MODIS), though they have subtle differences contributing to similar but not identical uses. The MODIS instruments were built by Santa Barbara Remote Sensing. They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together th ...

Greenbelt, Maryland
Greenbelt is a city in Prince George's County, Maryland, United States, and a suburb of Washington, D.C. At the 2020 United States census, 2020 census, the population was 24,921. Greenbelt is the first and the largest of the three experimental and controversial New Deal Greenbelt Towns, the others being Greenhills, Ohio, and Greendale, Wisconsin. Greenbelt was planned and built by the Federal government of the United States, federal government as an all-white town. The cooperative community was conceived in 1935 by Undersecretary of United States Department of Agriculture, Agriculture Rexford Tugwell, Rexford Guy Tugwell, whose perceived collectivist ideology attracted opposition to the Greenbelt Towns project throughout its short duration. The project came into legal existence on April 8, 1935, when United States Congress, Congress passed the Emergency Relief Appropriation Act of 1935. Under the authority granted to him by this legislation, President of the United States, Presid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
