Data quality at this site is very good. All daytime data are present. Passing or low-level
flags are assigned to 91.2% of the present daytime data. Another 5.8% of the data are
labeled strange-but-true. Low- to mid-level flags in the late afternoon to early evening
indicate that the DS is too low by the three-component test. Late in the month overcast
skies drove the DS and DD signals below twilight or daytime empirical limits. Shortly after
noon on the 14th a possible instance of cloud refraction is recorded in the DS. On the
afternoon of the 19th the DS and DD signals fall into the physically impossible region of
K-space. The DD signal is recorded as missing (-99999) by the data logger in a few
short-lived instances (1-3 in duration minutes each) early in the afternoon of the 25th. Both
the UIR and DIR signals continue to be noisy. No problems were noted in the US signal. |
