| Subject: | NSA/SKYRAD/C1 - NIP shaded by skyrad stand around local midnight |
| DataStreams: | nsaskyrad60sC1.a1 |
| 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. |
