Subject: | TWP/MPL/C1 - SunShade timing problem |
DataStreams: | twpmplC1.00, twpmplC1.a1, twpmplcmask1clothC1.c1, twpmplsmask1clothC1.c1
|
Description: | For an unknown reason, the sun shade was dropping for less then 10 minutes during the
night at about 19:00 UTC between Dec 14, 2003 and Feb 17, 2004. Data taken during that ten
minute interval is not looking at the sky and should be considered as though it were
missing.
This is a fairly small effect. Data users can simply average across the interval or block
the records as "missing". |
