If profiles of atmospheric variables are required the AAPP can be used in conjunction with an inversion package. AAPP radiance data are also used directly as input to variational data assimilation systems at several leading centres for Numerical Weather Prediction.2011-07-14-licenselicenseAAPP2011-07-14-180.0 -90.0180.0 90.0
