Subject:	SGP/IRT10m/C1 - Reprocess: IRT insufficiently insulated
DataStreams:	sgpirt10mC1.b1
Description:	The upwelling IRT on the 10m tower was insufficiently insulated to maintain an internal reference temperature above 0 degrees C. Measurements of surface temperature were over-estimated when instrument was below freezing. Data will be reprocessed, but users can correct data using the following correction factor: If T_reference < -5?C, then IRT_corrected = (IRT_original - 32.993K)/0.87238 where T_reference can be estimated with ambient temperature (e.g. inst_up_long_hemisp_dome_temp or inst_up_long_dome_temp from SGP.E13 SIRS)
Measurements:	sgpirt10mC1.b1: Surface Infra-Red Temperature Maxima(sfc_ir_temp_max) Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std) Surface Infra-Red Temperature Minima(sfc_ir_temp_min) Effective Surface (Skin) Temperature(sfc_ir_temp)

Subject:	SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR Header
DataStreams:	sgp30ebbrE12.b1, sgp30ebbrE13.b1, sgp30ebbrE15.b1, sgp30ebbrE20.b1, sgp30ebbrE22.b1, sgp30ebbrE26.b1, sgp30ebbrE4.b1, sgp30ebbrE7.b1, sgp30ebbrE8.b1, sgp30ebbrE9.b1
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 7/4/93. This DQR applies to all 30m EBBR data.)
Measurements:	sgp30ebbrE26.b1: soil_heat_capacity_5 soil_heat_capacity_4 soil_heat_capacity_2 soil_heat_capacity_3 soil_heat_capacity_1 sgp30ebbrE9.b1: soil_heat_capacity_1 soil_heat_capacity_2 soil_heat_capacity_3 soil_heat_capacity_4 soil_heat_capacity_5 sgp30ebbrE7.b1: soil_heat_capacity_1 soil_heat_capacity_2 soil_heat_capacity_5 soil_heat_capacity_3 soil_heat_capacity_4 sgp30ebbrE4.b1: soil_heat_capacity_1 soil_heat_capacity_2 soil_heat_capacity_3 soil_heat_capacity_4 soil_heat_capacity_5 sgp30ebbrE12.b1: soil_heat_capacity_2 soil_heat_capacity_1 soil_heat_capacity_5 soil_heat_capacity_4 soil_heat_capacity_3 sgp30ebbrE15.b1: soil_heat_capacity_1 soil_heat_capacity_2 soil_heat_capacity_3 soil_heat_capacity_4 soil_heat_capacity_5 sgp30ebbrE22.b1: soil_heat_capacity_5 soil_heat_capacity_4 soil_heat_capacity_3 soil_heat_capacity_2 soil_heat_capacity_1 sgp30ebbrE13.b1: soil_heat_capacity_1 soil_heat_capacity_5 soil_heat_capacity_4 soil_heat_capacity_3 soil_heat_capacity_2 sgp30ebbrE8.b1: soil_heat_capacity_3 soil_heat_capacity_2 soil_heat_capacity_5 soil_heat_capacity_4 soil_heat_capacity_1 sgp30ebbrE20.b1: soil_heat_capacity_2 soil_heat_capacity_3 soil_heat_capacity_4 soil_heat_capacity_5 soil_heat_capacity_1

Subject:	SGP/SWATS/E13 - Reprocess: Changed Depth Dimension
DataStreams:	sgpswatsE13.b1
Description:	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.
Measurements:	sgpswatsE13.b1: depth(depth)
