depth data were collected.
Measurements:sgp30smosE25.a1:
  • Snow Depth Sensor(snow_sen)
  • Snow Depth(snow)
sgp1440smosE25.a0:
  • Maximum Snow Depth(max_snow)
  • Time of Maximum Snow Depth(time_max_snow)
  • Time of Minimum Snow Depth(time_min_snow)
  • Minimum Snow Depth(min_snow_depth)

SGP/SMOS/E25 - 6-month Calibration Checks
DataStreams:sgp1440smosE25.a0, sgp1smosE25.a0, sgp30smosE25.a1
Description:
During the time periods specified, the SMOS.E25 tower was
lowered for 6-month Calibration Checks.  During these times 
wind data are incorrect and temperature and humidity data 
may be incorrect.

Note, exact times when tower was down or maintenance was
being performed is sometimes unknown.  Users should use
the remaining data from these days with caution.
