Under normal conditions, uncertainty for rain is +/- 0.254 mm (one bucket). Uncertainty increases to an unknown value during strong winds or very heavy rains (in excess of 75 mm per hour). The instrument is not considered reliable for snow amounts.

postprocessing_description :
The c1 level datastream uses generic average correction coefficients (based on analysis of many years of actual site pairings) for IR loss in the unshaded pyranometer measurements. The c2 level datastream uses more advanced correction coefficients calculated by the gswcorr1dutt VAP. Radiometers are replaced each year and c2 level correction coefficients are calculated for each radiometer pair (PSP and collocated PIR) separately for each site for each deployment year. Variables potentially affected by the updated correction coefficients are: down_short_hemisp and BestEstimate_down_short_hemisp and their associated qc and aqc flags
