On and around the summer solstice, the NIP (Direct Normal shortwave measurement) and PSP (global hemispheic shortwave measurement) radiometers are shaded by other instruments or support structures. Shading azimuths have been determined for this site. The radiometer mentor suggests not using the data from the NIP and PSP radiometers when the sun is within the following azimuth bounds (typically from May 8th to August 5th of each year): Instrmt Obstruction AzStart AzEnd NIP rad table 346 358 NIP met tower 13 15 PSP mfrsr 6 16
