Subject:	SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR Header
DataStreams:	sgp30baebbrE18.c1, sgp30baebbrE19.c1, sgp30baebbrE2.c1
Description:	The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. (NOTE: The actual begin date of some of these data streams is as early as 5/22/97. This DQR applies to all 30m EBBR data.)

Subject:	SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient
DataStreams:	sgp30baebbrE19.c1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:	The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage calibration) was incorrect. Negative net radiations during the subject period can be multiplied by 0.9419 to get corrected net radiation measurements. The sensible (H) and latent heat (LE) fluxes (which are very small at night anyway) can be recalculated using the following equations (where B is Bowen ratio, Rn is corrected net radiation, and G is soil heat flow): LE = -(Rn + G)/(B + 1) H = -(Rn + G + LE)
Measurements:	sgp5ebbrE19.b1: net_radiation sgp30baebbrE19.c1: latent heat flux(e) net radiation(q) h(h) Aerodynamic Sensible heat flux(ah) Aerodynamic Latent heat flux(ale) sgp30ebbrE19.b1: sensible_heat_flux latent_heat_flux net_radiation

DataStreams:	sgp15ebbrE19.b1, sgp30baebbrE19.c1, sgp30ebbrE19.b1
Description:	The latitude, longitude and altitude of the El Reno (E19) site were incorrectly entered into the ARM database. The correct location of the EBBR.E19 instrument is: Lat: 35.557N Lon: 98.017W Alt: 421m

Subject:	SGP/EBBR/E19 - BA EBBR VAP Bulk Aerodynamics
DataStreams:	sgp30baebbrE19.c1
Description:	Fixed AEM and wind speed sensor heights were improperly used in the calculation of bulk aerodynamic sensible and latent heat fluxes instead of site specific heights. This resulted in either under-estimation or over-estimation of the sensible and latent heat fluxes.
Measurements:	sgp30baebbrE19.c1: Best estimate Sensible heat flux(hcomb) Best estimate Latent heat flux(ecomb) Aerodynamic Sensible heat flux(ah) Aerodynamic Latent heat flux(ale) Friction velocity(austar)
