Subject: | NSA/SKYRAD/C1: Noisy PIR data at Barrow |

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. |
