TWP/SKYRAD/C1 - Apparent logger problem

Description:
Beginning at 0620Z on 13 July, all Manus SKYRAD measurements deviated wildly from expected 
values.  The longwave fluxes climbed to well over the expected maximum of 500 W/m^2 to 
values over 1000 W/m^2.  At the same time, shortwave flux components developed large 
inconsistancies and night-time offsets.  Values had somewhat returned to normal ranges by 
2200Z on 14 July but again developed internal inconsistancies between 0430 and 1900Z on 15 
July.  The instruments appeared to be working normally once again as of 1900Z on 15 July.  
It is not known what caused this period of faulty values but it is thought that an 
electrical surge - perhaps from a lightning storm (though none was reported) may have caused 
the temporary problems.

TWP/SWF/C2 - instrument grounding problem
DataStreams:twp15swfanalskyrad1longC2.c1, twp1swfanalskyrad1longC2.c1
Description:
A grounding problem with the skyrad data logger (discussed in DQR D090605.2) created 
intermittent anomalous voltages and incorrect flux data.  Measured all-sky fluxes and derived 
cloud fraction during these periods are incorrect. The identification of clear sky 
periods during these days and estimated clear sky fluxes may also be incorrect.  Days listed in 
this DQR are periods where bad data could be clearly identified; data from other days in 
this date range should be treated with caution.
