Subject:
TWP/QCRAD/C3 - Reprocess: NIP calibration incorrect
DataStreams:twpqcrad1longC3.s1, twpqcrad1longC3.c1, twpqcrad1longC3.s2, twpqcrad1longC3.c2
Description:
On 05/20 during installation of the new Campbell datalogger system and associated program 
the NIP (S/N 33551E6) was assigned an incorrect calibration coefficient.  A coefficient 
of 116.01 W/m2/mV was applied when it should have been 124.378 W/m2/mV.

Problem documented in instrument DQRs D050104.1 & D040904.2
Suggestions: 
Back out original mV measurement and reapply correct cal coefficient.
