****************************************************************************** DORISMail 12-May-2004 14:45:04 Message No 0317 ****************************************************************************** Author: "Harald Schuh" Subject: IVS troposphere parameters ------------------------------------------------------------------------ - Troposphere parameters provided as IVS products - ------------------------------------------------------------------------ Dear colleagues, we would like to inform you that the International VLBI Service for Geodesy and Astrometry (IVS) operationally provides estimates of the total and wet zenith delays together with the meteorological parameters (temperature, pressure, relative humidity) recorded at the VLBI stations. The final series are obtained by combination of individual submissions of 6 IVS Analysis Centers. These time series might be useful for those of you investigating differences between tropospheric parameters derived from different techniques (GPS, VLBI, DORIS, WVR, ..) at co-located sites. More details can be found at: http://ivscc.gsfc.nasa.gov/service/cddis-products-trop.html and http://www.hg.tuwien.ac.at/~ivstrop . Questions can be addressed to Johannes Boehm (johannes.boehm@tuwien.ac.at) and the IVS TROPO group would be glad for any feedback.
