| Subject: | NSA/METTWR/C1 - Instrument problem, Contamination, False signal |
| DataStreams: | nsamettwr4hC1.b1 |
| Description: | Heavy, wet and blowing snow and ice caused measurement problems with the sonic anemometer mounted at the 2m level. Erroneous readings caused both the wind speed and direction values to be reported anomolously. Once the heavy, wet snow and ice stopped the readings returned to normal. |
| Suggestions: | Use the wind speed and direction values from the cup and vane at the 2m level. |
