Subject:
TWP/QCRAD/C2 - Tracker failure
DataStreams:twpqcrad1longC2.c1, twpqcrad1longC2.c2, twpqcrad1longC2.s1, twpqcrad1longC2.s2
Description:
Tracker appears to be out of alignment or inoperative during these times. The 
short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data appear to be bad and not 
recoverable.

Several of these periods are documented in instrument DQRs:

D110831.1, D090328.1, D081222.3, D040107.1, D011207.1, D011019.8

Subject:
TWP/SKYRAD/C2 - Downwelling LW #1 questionable
DataStreams:twpskyrad20sC2.a0, twpskyrad60sC2.b1
Description:
Hemispheric downwelling measurements on the hemisp1 were suspect due to the large 
differences between PIR1 and PIR2 (i.e. greater than 10W/m2). Maintenance on 3/14/2012 indicated 
problem with the connector and ops re-seated the connector on PIR 1. After the 
maintenance, PIR1 and PIR2 returned to tracking each other within 10W/m2 as typical.

  • down_long_hemisp1_max
  • inst_down_long_hemisp1_tp
  • down_long_hemisp1_std
  • down_long_hemisp1_min
