Subject: | GRW/MET/M1 - Reprocess: ORG Data has very small rainrate values |
DataStreams: | grwmetM1.b1 |
Description: | 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. |
