Dear Herve, >Dear colleagues, > >As you know all DORIS stations are equiped with >an integrated meteorological station measuring >pressure, temperature and humidity. >Installing and maintaining these equipments >involves quite a bit of work and expenses. >A survey is being carried out with the users of >DORIS data and products, to assess how useful >these in situ meteorological data are. >I am therefore asking the analysis centers: >- Do you use the temperature, pressure and >humidity values measured by the DORIS stations? No >- If you use these data: >-- how do you handle missing data (e.g. when a sensor is out of order)? >-- what would be the consequences on your >analyses if such data were no longer supplied >for the whole network? None except that we won't be able to do long term calibration of DORIS-only tropospheric results, unless using close-by GPS equipment We may want to keep some of these equipment (5-10 beacons?)
