Subject: | NSA/ORG/C1 - Optical Rain Gauge incorrect at very low temperatures |
DataStreams: | nsaorgC1.a1, nsaorgC1.b1 |
Description: | The ORG reports precipitation rates that are more than 2 orders of magnitude greater than those reported by the present weather sensor when the temperature drops below -25 C. Examples of this error can be seen in the data for January 11-13, 2000, however the problem is not isolated to these days. A drift occurs when temps are in the range of -25 C to -40 C that exceeds the maximum drift allowed/expected for the instrument. The drift is then reported as precipitation. The manufacturer of the instrument has not yet been able to identify a fix for the problem. |
