GRW/MET/M1 - Tower lowered during installation

Data was collected during set up and installation.  Any data collected is suspect due to 
the tower being lowered and calibration checks occurring.  The data should be viewed 
critically before being used.

GRW/MET/M1 - Temperature/RH Aspirator Failure

The aspirator fan on the solar shield failed causing incorrect readings on the temp, RH 
and calculated variables.

GRW/MET/M1 - Reprocess: ORG Data has very small rainrate values

The ORG data is collected via analog signal and not digital.  Therefore, we continuously 
collect data even when no rain is occurring.  We also capture small events such as leaves, 
large bugs, dust, etc blowing through the measurement path.  Because this discrete event 
occurs quickly the value is usually captured for 1 or 2 seconds.  This value is then 
averaged to the minute producing rainrate on the order of .009 mm/hr or less.  

These values are not indicative of rain and should be removed from the record or summing 
over long periods can bias the climate record.  We will reprocess the data to remove these 
small values.
