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.
