  skos:definition """Infrared spectrometer is atmospheric sounding instrument, mainly by detecting the Earth's surface and atmosphere up IR-band emission of radiation, inversion get from surface to about 40 km to the different level of distribution of atmospheric temperature and humidity.Infrared spectrometer a total of 26 spectral channels for numerical weather prediction models provide initial field information, especially in the mountains, oceans, to the scarcity of desert areas such as meteorological station, an irreplaceable role to play.Using infrared spectrometer inversion resulting atmospheric temperature and humidity of the vertical distribution of information also reflects the local atmosphere of stability and helps the Meteorological Department and small scale weather systems forecast analysis.Infrared spectrometer data and microwave thermometer, implemetation data not only in conjunction with the temperature and humidity can improve accuracy, you can cloud, rain, three-dimensional weather process internal temperature and water vapor distribution structure, such as typhoons, storm for severe weather monitoring and prediction of the process of providing a strong support.
