NOAA have announced that the SNPP and NOAA-20 OMPS Ozone Nadir Profile (NP) products, currently distributed on EUMETCast, will be upgraded to a new version of the V8Pro algorithm.

Main changes include:

  • Modified scripts and codes to add option for running J02 for V8Pro algorithm, added required tables and ancillary files for J02.
  • Replaced old RT tables and triangular slit internal bandpass models with new RT tables and new higher-fidelity models.
  • Updated soft-calibration for aerosol channel of S-NPP retrievals and make the averaged AI at Equatorial Pacific equal to zero. Set soft-calibrations for both N20 and J02 to be zero for later adjustments.

As a result, filenames will change, as shown below:
