SGP/IRT25m/C1 - Odd Instantaneous Surface IRT data
DataStreams:sgpirt25mC1.a1
Description:
The sgpirt25mC1.a1 data for variable
   inst_sfc_ir_temp
look odd.  Each day, the first two records and the last 58 records have reasonable data 
but the remaining records are all zero. This behavior is seen all the way back to 20021121 
when the instantaneous variables were added to the sgpirt25mC1.a1 data stream.

The other instantaneous data variables do not show a similar pattern and the 60 sec 
sfc_ir_temp data look reasonable.
Measurements:sgpirt25mC1.a1:
  • Instantaneous Surface Infra-red Temperature(inst_sfc_ir_temp)

DataStreams:sgpirt25mC1.00, sgpirt25mC1.a1, sgpirt25mC1.a2, sgpirt25m20sC1.a0
Description:
The upwelling hemispheric shortwave measurement
   in the SGP.C1 IRT25m data streams for the time
   period noted requires a (-1) multiplier to correct
   for swapped connections at installation.

SGP/IRT25m/C1 - error in data logger program
DataStreams:sgpirt25mC1.a1, sgpirt25m20sC1.a0
Description:
On 12/16/2002, the logger software for the IRT25m was
inappropriately edited. This resulted in incorrect instantaneous
values at 20 and 40 seconds after each minute and incorrect 
calculation of 60-second averaged instantaneous values (because
the 20 and 40 second values are two of three instantaneous
values used to calculate this average). On 5/21/2003, the data
logger program was corrected.
