Subject: | NIM/MET/M1/S1 - Reprocess: ORG Data has very small rainrate values |
DataStreams: | nimmetS1.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 are reprocessing the data to remove these small values and are adjusting the collection program to remove them before ingest. |

Subject: | NIM/MET/S1 - Wind Speed data contain offset due to induced voltage |
DataStreams: | nimmetS1.b1 |
Description: | The marine model of the RM Young wind sensor needs twisted pair shielded cable. The manufacturer did not originally supply the pigtail with twisted pair shielded cable. Use of twisted pair shielded cable for the rest of the cable run to the logger was also not specified. This caused an induced voltage in the wind speed line from the wind direction excitation. The induced voltage varied from sensor to sensor and probably changed anytime the cable was replaced or parts of the wind sensor were repaired or replaced. The induced voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s. |

Subject: | GRW/MET/M1 - Tower lowered during installation |
DataStreams: | grwmetM1.b1 |
Description: | 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. |
