NN Radiation

Developing fast and accurate NN LW- and SW radiations for GFS and GEFS. NN LW- and SW radiations have been successfully developed for previous version of GFS, see: doi: 10.1175/2009MWR3149.1 and the stability and robustness of the approach used was demonstrated, see: https://arxiv.org/ftp/arxiv/papers/2103/2103.07024.pdf NN LW- and SW radiations will be developed for the current versions of for GFS and GEFS.
