FY3A Total Ozone Unit (TOU) Level 1 data Product
Entry ID: FY3A_TOU_L1

Abstract: Level 1 data set of FY-3A Total Ozone Unit (TOU):

L1 data set contains all TOU sensor data including atmospheric radiance and solar flux for 6 spectral bands,it also contains in-flight calibration data for solar flux and geo location data

Purpose: Level 1 data set of FY-3A Total Ozone Unit (TOU):
The total ozone unit(TOU) is an instrument on board the FY-3 polar orbiting satellite, is designed to provide daily global coverage of the Earth?s total ozone by measuring the solar backscattered ultraviolet at six spectral bands, with 1.1-nm bandpass in average. The TOU also makes periodic measurements of the solar flux by deploying 3 diffusers plate to reflect sunlight to the instrument. The instantaneous field of view (IFOV) is 3.6��� and the spatial resolution is 50km in nadir. Then scanning range is ���55.8��� and scanning set is 3.6���
