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.

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

GAN/GNDRAD/M1 - Incorrect up_long_hemisp

The up_long_hemisp values from the pyrgeometer were much too low, hovering near or just 
above 100 W/m^2.  This was particularly noticeable when comparing these values to those 
derived from the surface IRT.   

On 10/05/11, at 0348Z, tower was lowered for removal of PIR SN35836 and installation of 
PIR SN35839; tower raised at 0444Z. Following installation of PIR SN35839, data quality 
plots indicate proper up_long_hemisp values.
