Subject: | FKB/MET/M1 - Optical Rain Gauge Data Incorrect |
DataStreams: | fkbmetM1.b1 |
Description: | The optical rain gauge (ORG) data was incorrect during the listed times. Ice/frost was forming on the lenses causing the ORG to believe there was precipitation occurring. |

Subject: | FKB/MET/M1 - ORG Data incorrect during calibration |
DataStreams: | fkbmetM1.b1 |
Description: | The ORG data was incorrect during calibration checks. The check mimics a precipitation event so the precip amounts that were collected were not actually measured. |

Subject: | FKB/MET/M1 - Incorrect ORG data |
DataStreams: | fkbmetM1.b1 |
Description: | Precipitation was being reported on days with no rain. Problems with the grounding and the orientation of the receiver facing south (sunlight in the optics) caused erroneous readings. |

Subject: | FKB/MET/M1 - ORG reporting precip constantly |
DataStreams: | fkbmetM1.b1 |
Description: | During the time period listed the ORG reported precip consistently. Reason unknown as deployment ended before resolution of problem. |

Subject: | FKB/MET/M1 - Wind Speed data contain offset due to induced voltage |
DataStreams: | fkbmetM1.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. |
