By Level:

By Category:


  • conPhs(atmPhs): Link | File Description

    Atmospheric excess phases and auxiliary data used for generating atmospheric profiles. Removal of clock errors is based on single differencing. The velocity precision of the atmPhs files is estimated to be less than 0.15 mm/sec RMS.

  • atmPrf: Link | File Description

    Atmospheric profiles of bending angle, refractivity, and dry temperature.

  • avnPrf: Link | File Description

    Temperature, pressure and moisture profiles generated from the NCEP AVN 12 hour forcast files and colocated with occultation profiles.

  • echPrf: Link | File Description

    Temperature, pressure and moisture profiles generated from the ECMWF high resolution gridded analysis and colocated with occultation profiles

  • wetPf2(wetPrf): Link | File Description

    Atmospheric profiles of refractivity, temperature and water vapor. These profiles are based on 1D variational analysis using GFS 47 level 12 hour forecast data (found in the avnPrf files).

  • bfrPrf: Link | File Description

    Contains results in BUFR format from both atmPrf and wetPf2. The refractivity profile in bfrPrf is equivalent to the one in the corresponding atmPrf file, but may differ from the one in wetPf2.

Raw GPS Data

  • trgLv0: Link | File Description

    This file contains level 0 (raw binary) data from the COSMIC-2 TRIG GNSS Receiver Payload.

  • opnGns: Link | File Description

    Atmospheric occultation data in a simple custom binary format. This data file contains all high rate atmospheric data sent us by the GNSS receiver on the LEO.

  • podCrx: Link | File Description

    Raw L1 and L2 pseudo-range and carrier phase tracking data in compressed RINEX 2.20 format

  • leoAtt: Link | File Description

    Attitude and rough position data from the COSMIC spacecraft andthe GOX navigation solutions.

  • leoOrb: Link | File Description

    Precise COSMIC spacecraft orbits. The orbit precision based on internal orbit overlap comparisons is on average less than 15 cm 3D RMS (0.15 mm/sec 3D velocity).
