Subject:
TWP/QCRAD/C3 - Tracker inoperative
DataStreams:twpqcrad1longC3.s1, twpqcrad1longC3.c1, twpqcrad1longC3.s2, twpqcrad1longC3.c2
Description:
Tracker inoperative because hit by lightning. Diffuse and direct normal shortwave 
irradiance incorrect during this time. LW downwelling data can have higher uncertainties under 
direct sun.

Problem described in instrument DQR D090129.1
Suggestions: 
null
