Description: | Data quality this site-month is good. The offset in the Global PSP has been much improved,
with an average nighttime offset of -4 W/m^2, since measures were taken on 17 DEC 2004
to fix it. The Global PSP does not go below nighttime empirical limits all month. Global
does fall below daytime empirical limits for significant time periods on the 2, 4, 5, 12,
28, 30. There were still substantial 3 component flags 17 DEC 2004. The charcteristic
three component failures are present through out the month, especially closer to the end of
the month. The problem is about equally as bad in the morning as the evening.
The flags are usually high level yellow at their worst for any given day. Finally, there
are the typical three component flags on the 29th as well, but these occur under cloudy
skies. The data return to normal the next day and a cause for the problem cannot be
determined. |
