the high end of the shortwave band the path of these rays are very similar. At the low end they are not. As a result there can be significant advantage to using circularly polarized receiving antennas to establish reliable long range communications. In some instances such antennas will be ...
Finally, the radiative processes are parameterized by means of the longwave and shortwave RRTMG schemes [33]. The initial and lateral boundary conditions are derived from NCEP-GFS (National Centers for Environmental Prediction Global Forecast System) analysis and forecast data available at a horizontal...
FLAASH is a first-principle atmospheric correction tool that corrects wavelengths in the visible through near-infrared and shortwave infrared regions up to 3 μm. It incorporates the MODTRAN 4 radiation transfer code. FLAASH is widely used to eliminate the effects of the atmosphere, and convert ...
