  1. GPS Comparisons John J. Braun COSMIC Program University Corporation for Atmospheric Research Boulder, Colorado

  2. Outline • Comparisons to Water Vapor Radiometer • ARM radiometrics instruments • Comparisons to Year 2001 • Comparison of GPS Processing Packages

  3. NOAA/FSL and DOT Stations OU/ARM/SuomiNet Stations Special Stations for IHOP GPS Stations In IHOP_02 Region HBRK LMNO VCIO HKLO 41 Stations Total PRCO

  4. ARM Central Facility - Lamont, OK (LMNO)

  5. ARM Central Facility - SuomiNet Station

  6. Station Hillsboro, KS (HBRK)

  7. Station Haskell, OK (HKLO)

  8. Station Purcell, OK (PRCO)

  9. Station Vici, OK (VCIO)

  10. IHOP Results Compared to YR 2001 Results

  11. Conclusions • GPS - WVR Comparisons have been made • Only comparing PW results. • There have been no quantitative comparisons of SW and tomography • GPS tends to be dry with respect to WVR. • GPS solutions between processing packages have not been completed yet for IHOP 2002, but previous comparisons show very good agreement.
