Platform/Measurement:SIROS
        What level data: (raw,a0,a1,b1,c1 etc):

    What location was the data collected at: CF
 
    Period of time in question
        Begin Date  01/12/94   Time       (GMT)
        End Date    04/15/94   Time       (GMT)

 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 ___  incorrect                         ___  Only some data fields affected
 ___  wrong calibration
 ___  others 
 
 Discussion of Problem:

The data Header for the Ventilated Pyrgeometer case temperature
on the SIROS platform at the Central Facility is incorrect.  At
the present time the units are Watts/M2 and it should be degrees
C.

 
Other observations/measurements impacted by this problem:



Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
