Subject: | NSA/SONDE/C1 - Wind data missing |
DataStreams: | nsasondewnpnC1.b1 |
Description: | A GPS problem associated with Vaisala BBSS ground station software issues caused the ground stations to enter into an error state when using GPS wind finding. In some instances, the flight was aborted due to the error state and not data was collected. A workaround was developed to allow sondes to be launched without collecting wind data. |

DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | All met data from the tower booms (temp, RH, winds and derived variables) were incorrect due to the booms being lowered from their measurement heights. Additionally, the scaffolding was located directly adjacent to the booms affecting the wind field and the Temp/RH data. |

Subject: | NSA/MET/C1 - 2m RH values incorrect |
DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | The new t/rh probe installed during annual calibrations and checks began to exhibit readings that were biased high compared to the Chilled Mirror Hygrometer. In high RH conditions the sensor would consistently report RH values in excess of 105%. Comparisons to the other tower levels also suggested that the 2m level RH data is suspect. |

Subject: | NSA/SONDE/C1 - Wind data missing |
DataStreams: | nsasondewnpnC1.b1 |
Description: | After some power disruptions, the Power Supply board of the SPS220 ground station was damaged. The damage caused the supply to not have enough power to run the GPS board. Switching to the back up DigiCora II did not alleviate the problem as the fix for GPS failure to all Vaisala sonde products had not been installed. A different P/S was found and sent up to replace the failed one. |
