GAN/GNDRAD/M1 - IRT calibration error

The IRT surface temperature reported was incorrect because the analog output configuration 
did not agree with the data logger scale factors. The IRT configuration was corrected on 
10/9.

• Effective Surface (Skin) Temperature(sfc_ir_temp)
• Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
• Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)

GAN/SKYRAD/M1 - Instrument maintenance, Degraded hardware

The gold mirror for the upward looking IRT is showing discoloration and appears to be 
worn.  I plan on replacing the mirror with a spare that is on site.
