Subject:	TWP/SKYRAD/C1 - Apparent logger problem
DataStreams:	twpskyrad60sC1.b1, twpskyradC1.00, twp1swfanalskyrad1longC1.c1, twpskyrad1duttC1.c1, twpskyrad20sC1.a1, twp15swfanalskyrad1longC1.c1
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.
