cox_and_munk_u10_map filewhere file is the location of the netCDF file. libRadtran reads the value at the nearest pixel to the given latitude and longitude. No spatial interpolation or averaging of the values is done.
The file must contain the elements of the wind vector U10 and V10. These must be specified as functions of latitude and longitude U10(lat, lon), V10(lat, lon), or additionally may also depent on time U10(time, lat, lon), V10(time, lat, lon). If the variable time is present in the file, the wind speed will be interpolated according to the option time_interpolate. All grids must be provided as double lat(lat), double lon(lon), and double time(time).
