SGP/MFRSR/E22 - Data not quality assured

Data from October 1, 1999 through March 2001 from MFRSR.E22 should be used with caution. 
During this time period only minimal quality control and maintenance were provided to the 
SGP extended facility MFRSRs because these data were considered to be of questionable 
value under the best of circumstances. That decision was reversed in  2001 when Joe 
Michalsky identified a means to make the MFRSR data scientifically useable.

In the interim, the MFRSRs developed problems with shading, leveling, calibration and 
all-out hardware failures and the stock of spare MFRSRs was depleted and not replenished. 
Most of the shading and leveling problems have now been corrected in the field as well as 
possible, but almost all of the extended facilty MFRSRs still need to be recalibrated or 
replaced.
