Description: | 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):
Instr Obstruction AzStart AzEnd
NIP rad table 356 17
PSP mfrsr 341 353
Note: There are a number of objects near the NW,N and NE horizon that may affect sunrise
data near the summer soltice. |
