SGP/EBBR/E20 - Wrong Datalogger Program Installed
DataStreams:sgp30ebbrE20.b1
Description:
ts4 went offscale and sm4 dropped to a constant 16% when a "new" program
was installed on 3/30/05.  The wrong program was installed.

Because ts4 did not change with time, it did not mess up the calculation
of e and h.  e and h are slightly overestimated, but only by about 1%,
far less than the system error. This is a rare type of instrument problem where the 
concequences are minimal.

Therefore, e and h are not listed as incorrect in this DQR and are still usable during the 
stated period.
Suggestions: 
Measurements:sgp30ebbrE20.b1:
  • Surface soil heat flux 4(surface_soil_heat_flux_4)
  • Soil heat flow 4, corrected for soil moisture(corr_soil_heat_flow_4)
  • Soil heat capacity 4(soil_heat_capacity_4)
  • Soil moisture 4, gravimetric(soil_moisture_4)
  • Change in energy storage 4, 0-5 cm soil layer(energy_storage_change_4)
  • Half hour averaged soil temperature 4(soil_temp_4)
