LSE, Atmospheric transmittance, upward and downward atmospheric radiation for GF-5B

The Thermodynamic Initial Guess Retrieval (TIGR) data set, in its latest version, is a climatological library of 2311 representative atmospheric situations selected by statistical methods from 80,000 radiosonde reports (Chédin et al., 1985; Achard, 1991; Chevallier et al., 1998). Each situation is described, from the surface to the top of the atmosphere, by the values of the temperature, water vapour and ozone concentrations on a given pressure grid.
