Subject:
NIM/SKYRAD/M1 - IRTs do not agree with AERI
DataStreams:nimskyrad60sM1.b1
Description:
Since deployment at PYE, and then at NIM, the AMF SKYRAD IRT measured about 10K higher sky 
temperatures than the AERI and the MWRP IRT measureed about 20K higher than the AERI.  
Several actions were taken to diagnose the problem including confirming the correct 
configuration of the IRTs and data logger, cleaning the mirror and lens, and replacing the mirror.

After several days of rain beginning 6/2/2006, the three instruments came into agreement. 
It is unknown whether this was a problem with the AERI, MWRP-IRT or SKYRAD-IRT.
Measurements:nimskyrad60sM1.b1:
  • Sky/Cloud Infra-Red Temperature(sky_ir_temp)
  • Sky/Cloud Infra-Red Temperature Minima(sky_ir_temp_min)
  • Sky/Cloud Infra-Red Temperature Maxima(sky_ir_temp_max)
