DataStreams:sgpaosacsmC1.b1
Description:
A closure analysis is currently being perform on the ACSM, TDMA, and wet and dry NOAA 
NEPHELOMETERS at SGP C1. If problems are found during this analysis, they will be promptly 
documented through the DQR system.  The results of this analysis will be made available 
once completed.  Please contact the respective instrument mentors with any questions 
regarding these data over the specified period.
