Weather Balloons Vs. MERRA-2  (report from Augustin Guyonnet)

DM-15279 - Getting issue details... STATUS

Temperature and pressure profiles are used as an input for the determination of the   Rayleigh scattering from radiative transfer simulation.

The question wether or not MERRA-2 3D interpolated tables are accurate enough to be used as an input for the simulation can be answer by checking the interpolations against weather balloons soundings.

Daily launches are reported from Antofagasta Airports.

The data have been retrieved ( https://www.ncdc.noaa.gov/data-access/weather-balloon/integrated-global-radiosonde-archive), processed, and compared to MERRA-2.

The preliminary findings are presented in this pdf :
