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?)

Best regards
Pascal
