IVS Pilot Project - Tropospheric Parameters

Introduction Based on the very promising results of the 2nd IVS Analysis Pilot Project (Boehm et al., 2002) the IVS Directing Board decided in April 2002 to set up the ‘Pilot Project – Tropospheric Parameters’. The Institute of Geodesy and Geophysics (IGG) of the Vienna University of Technology was appointed as coordination center of the new Pilot Project (PP). After the Call for Participation six IVS Analysis Centers (ACs) (see Table 1) agreed to contribute to the PP by regular submissions. They have been submitting results of tropospheric estimates of all IVS-R1 and IVS-R4 24h-sessions since January 1st, 2002.
