PYE/NFOV/M1 - Intermittent missing data

During the Pt Reyes deployment of the NFOV, the instrument experienced intermittent data 
gaps due to communications problems.  Data gaps occurred for the following date ranges:
20050718-20050723
20050727-20050730
20050803-20050804
20050813-20050816
20050820-20050822
20050826-20050827
20050830-20050902
20050908-20050910

PYE/NFOV/M1 - Intermittent data gaps

Intermittent data collection of the NFOV.  Data collection not successful regularly during 
day light hours but generally caught up during the nighttime hours.  Occasionally the 
system stopped collecting altogether and a reboot of the network components was required to 
restart collection. Data gaps are largest 18 through 23 of July and 27 through 30 July.

PYE/SKYRAD/M1 - Reprocess: Longwave Calibration error

Modified pyrgeometer calibration procedures were implemented beginning in December 2003.  
These modified procedures introduced a calibration bias in the longwave data.  The 
previous procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations.                                                             
                The data collected while the incorrect procedures were in place are 
being reprocessing to remove the calibration bias.  Note, this also affected standard 
deviation, maximum and minimum data fields.
