[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.
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]
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting.

The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. [5] TIROS operated for 78 days and proved to be much more successful than Vanguard 2. Other early weather satellite programs include the 1962 Defense Satellite Applications Program (DSAP) [6] and the 1964 Soviet Meteor series.
That way, you can adjust the temperature en route, so you don't come home to a chilly house. Related: The 6 Best Smart Thermostats, According To Testing Other Ways to Conserve Energy in the Winter
Another satellite temperature analysis is provided by NOAA/NESDIS STAR Center for Satellite Application and Research and use simultaneous nadir overpasses (SNO) [25] to remove satellite intercalibration biases yielding more accurate temperature trends. The STAR-NOAA analysis finds a 1979–2016 trend of +0.129 °C/decade for TMT channel.

They measure radiances in various wavelength bands, from which temperature may be inferred.
