SGP/IRT/C1 - Noisy 10m IRT data
DataStreams:sgpirt10mC1.b1
Description:
The 10M IRT surface temperatures were very noisy because the connection to the data logger 
had become loose.
Measurements:sgpirt10mC1.b1:
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • internal_voltage
  • sfc_ir_temp_std
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • logger_temp

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:

SGP/IRT/C1 - 10m IRT ground surface temperature
DataStreams:sgpirt10mC1.b1
Description:
The 10m IRT was measuring lower ground surface temperature than the 25m IRT. The lens was 
cleaned on 12/19/2012 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:sgpirt10mC1.b1:
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • sfc_ir_temp_std
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
