Spire NRT atmospheric profile data files

File type Format contains
atm netCDF-3 observed profile (lat, lon, bending angle, refractivity, dry temperature, and tropopause height)
wet netCDF-3 observed profile (output from 1D-Var, i.e., temperature, pressure, humidity)
dis netCDF-3 observed profile (thinned products from the atm file together with products from the wet file)
bfr BUFR observed profile (bending angle, refractivity, and 1D-Var products from the dis file)
bgn netCDF-3 ECMWF operational analysis profile (bending angle, refractivity, temperature, etc.)
bgo netCDF-3 ECMWF operational forecast profile (bending angle, refractivity, temperature, etc.)

Download notes

Example to download all Spire atm files using wget (be aware that this may be a lot of data):
   wget -rN -np -A.tgz --user=xxxx --ask-password https://rom-saf.eumetsat.int/pub/nrt/profs/spire/atm

The individual files are packed in daily zipped tar files. Upon unpacking, the individual files are placed in a folder named after the date. The individual files for occultations that failed the ROM SAF quality control are placed in a subfolder named 'non-nominal'.
