Gas absorption cross section lookup table and a collection of data files used in the pace simulator

This tar file includes two directories. One is Gas_Absorption_Coefficients/, which contains the gas absorption cross section lookup table for H2O, O2, CH4, CO2, NO2, ozone. The other is Data/, which contains the absorption coefficients of pure water, plankton particles, the birectional reflectance distribution functions of snow surface, scattering matrix of dust particles, the instrument response functions of ocean color instrument, HARP2, and SPEXone, and a number of other data files used in the PACE simulator.
