Subject: [SLR-Mail]  No.2574: 7827 site and history log update
From: Stefan Riepl <riepl@fs.wettzell.de>

Author: Stefan Riepl

The 7827 site and history log needed an update, since the
latest calibration of the pressure sensor used at the Geodetic 
Observatory Wettzell revealed an offset of -0.25hPa. A backtracking 
analysis of the sensor offset revealed a drift of approx. 
-0.025hPa/year. As a consequence the existing pressure sensor was 
replaced by a calibrated one on 2019-05-28 18:15 UT.
Data recorded at 7827 after that date is delivered with correct pressure 
readings.
All data recorded and delivered before 2019-05-28 18:15 UT will be 
corrected in a new release which will be finalized during week 24.
The updated site log is awaiting approval at the EDC.
We regret for any inconvenience.

Best regards,

Stefan Riepl
