[1] [2] The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a result, different groups that have analyzed the satellite data have produced differing temperature datasets. The satellite time series is not homogeneous.
They measure radiances in various wavelength bands, from which temperature may be inferred. [1] [2] The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a result, different groups that have analyzed the satellite data have obtained different temperature data (see Microwave ...
One of the most important applications of thermal remote sensing in earth sciences is to calculate the Land Surface Temperature (LST). LST is a measurement of how hot the land is to the touch. It differs from air temperature (the temperature given in weather reports) because land heats and cools more quickly than air. [15]
Microwave brightness measurements do not directly measure temperature. They measure radiances in various wavelength bands, which must then be mathematically inverted to obtain indirect inferences of temperature. [1] [2] The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a ...
The 5.2 version of Christy et al.'s satellite temperature record contains a significant correction over previous versions. In summer 2005 , Mears and Wentz (2005) discovered that the UAH processing algorithms were incorrectly adjusting for diurnal variations, especially at low latitude.
The AIRS instrument flies on NASA's Aqua satellite. The atmospheric infrared sounder ( AIRS ) is one of six instruments flying on board NASA's Aqua satellite , launched on May 4, 2002. The instrument is designed to support climate research and improve weather forecasting .
The first weather satellite, Vanguard 2, was launched on February 17, 1959. [4] It was designed to measure cloud cover and resistance, but a poor axis of rotation and its elliptical orbit kept it from collecting a notable amount of useful data. The Explorer 6 and Explorer 7 satellites also contained weather-related experiments. [3]
The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken as free of other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once ...
