SGP/IRT/C1 - Measurement range
DataStreams:sgpirt10mC1.b1, sgpirt25mC1.b1
Description:
The ground surface temperature exceeded the maximum measurement of 50C on some days. The 
maximum was increased to 60C for IRT10m on 10/1/2012 at 15:25 and for IRT25m on 10/9/2012 
at 21:45.
Measurements:sgpirt25mC1.b1:
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
sgpirt10mC1.b1:
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)

SGP/IRT/C1 - 25m IRT ground surface temperature
DataStreams:sgpirt25mC1.b1
Description:
The 10m IRT was measuring lower ground surface temperature than the 25m IRT. The 25m lens 
was cleaned on 12/24/2012 and replaced on 2/8/2013 but the difference in temperature 
appears to be due to the seasonal difference in surface cover - tall grass vesus bare soil.
Measurements:sgpirt25mC1.b1:
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • sfc_ir_temp_std
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)

Subject:
SGP/IRT/C1 - Degraded hardware
DataStreams:sgpirt25mC1.b1
Description:
The surface temperature from the 25m IRT was ~10K less than measured from the PIR. The 
lens was replaced on 2/8/2013 but there is still a bias. The problem was corrected when the 
IRT (and that at 10m) was upgraded to a newer model.
Measurements:sgpirt25mC1.b1:
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Instantaneous Surface Infra-red Temperature(inst_sfc_ir_temp)
  • sfc_ir_temp_std
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
