| Description: | Good data quality for this site this month. All data are present, and 92.5% of the present
daytime data earn passing or low-level flags. Another 6.1% of the daytime data are
flagged strange-but-true. Low-level flags in the early morning hours shortly after sunrise
indicate that the DS is too low, or the NIP or DD too high by the three-component test.
Low-level flags seen after noon in the second half of the month indicate that the DS is too
high. The DS and DD are forced below daytime empirical limits by overcast skies on several
occasions. Moderate to serious flags shortly after noon on the 14th indicate that the
DS signal is too high by the three-component test. On the 22nd at 1605 GMT the 10m tower
was taken down for upgrade. The UIR and US signal fields will be filled with the data
logger missing data flag, -99999, until the new tower is installed. Otherwise, data
collection will continue as usual. No problems noted in DIR signal. |
