Subject: | NSA/SKYRAD/C1 - NIP shaded by skyrad stand around local midnight |
DataStreams: | nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
|
Description: | Around local midnight 9:30-10:30 GMT during summer clear sky the normal incidence
pyranometer is shaded by the instrument stand.This causes the reading to be 0 W/m2. If cosine
correction is applied for irradiance calulations this effect is negligible due to the low
solar angle. |

Subject: | NSA/SKYRAD/C1 - PSP shaded by MFRSR after local midnight |
DataStreams: | nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
|
Description: | Just past local midnight (11:00-11:40 GMT during summer clear sky) the global
hemispherical pyranometer is shaded by the MFRSR instrument for about 40 minutes. This causes the
reading to be 0 W/m2. This effect would be negligible in a daily average due to the low
solar angle. |

Subject: | NSA/SKYRAD/C1 - NSA B&W nighttime offset in Barrow too large |
DataStreams: | nsaskyradC1.00, nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
|
Description: | This problem only became apparent as NSA C1 nights became long enough for full darkness.
The shaded global diffuse instrument (Eppley 8-48) showed a negative nighttime offset
larger than the expected 0 to -4 W/m2. Typically -5 to -8 W/m2. This size of offset is not
uncommon with Eppley PSPs but not observed with Eppley 8-48s. The problem was corrected
with replacement of mounting screws which were creating a ground loop. |

Subject: | NSA/SKYRAD/C1 - Summer solstice shading of radiometers |
DataStreams: | nsaskyrad60sC1.b1
|
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):
