SGP/SMOS/E7 - Snow depth sensor removed; data reported as missing

The snow depth sensor was removed from service.  The program was changed so that -9999 is 
entered into the datastream.

SGP/EBBR/E7 - Soil Heat Flow #5 Incorrect

Soil Heat Flow Plate #5 data was intermittently incorrect at first 
(values too small negative), then was almost constantly so during the 
last half of the period.

Comparison of the individual soil heat flows will quickly show the times
that soil heat flow #5 was incorrect.

SGP/EBBR/E7 - Pressure Sensor Data Incorrect

The E7 pressure sensor suffered
from spikes in pressure, which were related to 
increases in voltage during the day as the 
solar panels charged the battery.  These spikes
were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

SGP/SMOS/E7 - Reprocess: Wind direction offset

When the SGP.E7 SMOS tower was installed it was not aligned
properly resulting in a 6 degree offset.  On 3/08/05, the
datalogger program was modified to correct for this offset.

• Unit Vector Wind Direction(wdir)

SGP/SWATS/E20 - Reprocess: Changed Depth Dimension

The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.

• depth(depth)

SGP/SWATS/E13 - Reprocess: Changed Depth Dimension

The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.

SGP/EBBR/E13 - Improved EBBR CR10 Program

Effective 20050331.2100, the EBBR.E13 CR10 program was revised to improve the quality of 
the primary measurements as follows:

1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow.  
This is applied to the individual soil sets.  Measurements outside the limits are 
rejected and the measurements within the limits are used to calculate the average soil heat flow.

2) Max and min limits are used to determine incorrect values of net radiation, sensible 
heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal.  If AEM 
signal is outside the limits, h and e are set to 999s.  If net radiation is outside the 
limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s.

Virtually no incorrect soil measurement will affect the primary measurements of h and e.

By setting h and e to 999s, it can be easily seen that the primary variables are 
incorrect; no other interpretation is possible.

Prior to 20050331, the improved CR10 program was NOT in effect.  DQRs have been submitted 
for known instances of incorrect soil measurements which affected the quality of the 
primary measurements of h and e.

Note: the DQR begin date is the begin date of the sgp30ebbrE13.b1 data stream.  The 
earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. 
sgp30ebbrE13.a1).
