Subject:
PGH/SKYRAD/M1 - Reprocess: Incorrect calibrations
DataStreams:pghskyrad20sM1.a0, pghskyrad60sM1.b1
Description:
During the entire India deployment the Skyrad system was configured with incorrect 
calibration coefficients for the shortwave instruments. The program hadn't been updated since 
the previous deployment in the Azores.

The instrument mentor, site personal and OSS support have attempted to best determine the 
serial numbers of instruments installed at PGH during the deployment period.  The 
following instrument data will need to be reprocessed with the following correction multipliers:

PIR1-DIR(down_long_hemisp1): OK, no correction required
PIR2-DIR(down_long_hemisp2): OK, no correction required
Diffuse 8-48 (down_short_diffuse): 116.95(correct)/120.91(incorrect) = .96725
NIP (short_direct_normal): 127.03(correct)/124.97(incorrect) = 1.01648
PSP-DS (down_short_hemsip): 111.29(correct)/108.48(incorrect) = 1.02590
IRT: calibration should be validated by instrument mentor (Vic Morris): mult=26, 
offset=173.2

Correct serial numbers:   
Diffuse 8-48 (down_short_diffuse): 34066
NIP (short_direct_normal): 34135E6
PSP-DS (down_short_hemsip): 33942F3
