Subject:
NSA/CEIL/C1 - Reprocess: Intermittent data and clock drift
DataStreams:nsaceilC1.b1
Description:
The available processed data for the NSA.C1 VCEIL for the time period indicated are 
incomplete.  The raw data is largely complete but pre-processing is required before these data 
can be reprocessed to produce a complete netcdf data set.

While awaiting the reprocessed data set, the intermittent data are available from the ARM 
Archive.  Users should be aware that the data are additionally compromised by a clock 
drift of at least 10 minutes, though this likely has little affect on cloud detection 
results.  The clock drift will not be addressed by the reprocessing.

Note also, that the clock drift was corrected at the end of the DQR period, but it may 
have existed before the beginning of the DQR period.

The data for this period should be used with caution.
