UAH provide data on three broad levels of the atmosphere. The Lower troposphere - TLT (originally called T2LT). The mid troposphere - TMT; The lower stratosphere - TLS [3] Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the ...
The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator , [ 17 ] with some variation due to weather.
Temperature measurements are also made by GPS radio occultation. [31] This technique measures the refraction of the radio waves transmitted by GPS satellites as they propagate in the Earth's atmosphere, thus allowing vertical temperature and moisture profiles to be measured.
Calculation of lower troposphere temperature. In an attempt to derive data for lower altitudes and remove the stratospheric influence, several researchers have developed synthetic products that subtract the higher-altitude values from the lowest altitude (TMT) measurement. Such a data-analysis technique is dependent on modeling the effect of ...
The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending on latitude: for example, the troposphere is thicker in the tropics (about 16 ...
The name Limb refers to the "edge" of Earth's atmosphere. This data collected includes atmospheric gas profiles and atmospheric temperature and pressure. Tropospheric Emission Spectrometer (TES) [11] TES is an infrared sensor aboard AURA used to investigate the troposphere of Earth's Atmosphere.
With remote sensing instruments, the boundary layer height can be detected based on these principles. Using the lidar on board CALIPSO, boundary layer height estimates have been made and compared with radiosonde and ECMWF re-analysis data and have shown high correlations between the remote sensing estimated value and the measured radiosonde values.
The MOZAIC data is restricted access, to obtain access the forms need to be filled out. CARIBIC observations. The CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) project is an innovative scientific project to study and monitor important chemical and physical processes in the Earth's ...
