Subject:
SGP/EBBR/E15 - Annual calibration changeout
DataStreams:sgp5ebbrE15.b1, sgp30ebbrE15.b1
Description:
On December 14, 1995 the changeout for annual calibration occurred at E15,
Ringwood, OK.  Between 1650 and 2050 GMT no data was remotely collected.
Furthermore, 5 minute data for 2050 GMT is incorrect, 15 minute data for
2045 GMT is incorrect, and 30 minute data for 2100 GMT is incorrect.
A rather large jump in soil moisture appears in the data after the
installation was completed (the bags holding the probes were soaked with water
before installation).  Soil measurements indicated greater than ambient
soil moisture  until a rain on late 18 December saturated the soil; after this
period the probes reflected actual soil moisture conditions.  The larger than
normal soil moistures have little impact on the small soil heat flux during
this time of year, and thus no significant affect on computed sensible and
latent heat fluxes.
