SGP/IRT10m/C1 - Reprocess: IRT insufficiently insulated

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)

• 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)

SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header

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.)

SGP/AERI/C1 - Reprocessed: radiance data

Due to a software error in the real-time calibration software, the AERI-01 radiance data 
between 10/96 and 6/97 were incorrectly calibrated. All of the AERI-01 radiance data 
collected at the SGP central facility during this time period was corrupted by this software 
error and were reprocessed to correct the radiance data.  The error also affected all 
derived products of the AERI radiance data.  AERI data collected prior to and after this time 
period was unaffected by this programming error.

The proper calibrated radiance spectra was recovered from the raw archived dataset through 
post-processing.  This reprocessing of the AERI data was carried out by the instrument 
mentor at PNNL and confirmed independently by Univ. of Wisconsin.  The reprocessed AERI 
radiance data during the period 10/96 to 6/97 supercedes all previous versions of the AERI 
data in all instances.
