New METOP-A and METOP-B mission climate reprocessing.
A new reprocessing of the METOP-A and METOP-B satellites GRAS receiver radio occultation payload has been done at CDAAC. It is available for download on the CDAAC Data Download interface and the FTP batch data download interface (select 'batch data download').
Look under the metopa2016 and metopb2016 missions.
New features of this reprocessing include:
- New excess phase code
- New inversion software used ('newroam'), resulting in much higher occultation counts
- Uniform GPS clock corrections
- First reprocessing of the METOP-B data, 2013-2015
We have switched over to a next generation inversion software called 'newroam' (new Radio Occultation Atmospheric Monitoring) written by Sergey Sokolovskiy, and Zhen Zeng of UCAR. This software has been in development for several years now and is ready for production after a year-long testing process with weather centers including ECMWF, NCEP, and DWD. Many thanks to all who helped in the testing.
