Subject: | ENA/OZONE/C1 - Reprocess: Under reporting ozone concentration |
DataStreams: | enaaosozoneC1.a1 |
Description: | Switching valve developed an internal leak that gradually worsened. Reported instrument values are under-representations of the ambient ozone concentration during this period. The under reporting worsens from 85% to 77% over the course of this DQR. No corrections have been applied at this point. |

DataStreams: | enaaoshtdmaC1.a1 |
Description: | The HT-DMA internal RH sensor was sending out data in a format that was not correctly interpreted by the instrument software. This led the software to assume an incorrect RH reading and set the humid and dry air flows at incorrect values, affecting RH and other internal flows. |

Subject: | ENA/MAO/OLI/PGH/PVC/SGP/TWP/DLPROF/C1/C3/M1 - Reprocess: Suspect error estimates |
DataStreams: | enadlprofwind4newsC1.c1 |
Description: | The current dlprofwind4news VAP generates time- and height-resolved estimates of wind speed, wind direction, and corresponding uncertainties from Doppler lidar PPI scans. A recent comparison with a heavily instrumented tall tower (BAO) has shown that the error estimates are biased low and exhibit poor correlation with the observed lidar-tower differences. We note that the measurements themselves (i.e. wind speed and direction) are minimally affected by this issue. |

Description: | Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be corrected. The respective GRW and ENA lat, lon, and alt values are as follows: GRW lat = 39.0911 ; ENA lat = 39.0916 ; GRW lon = -28.0297 ; ENA lon = -28.0257 ; GRW alt = 26 ; ENA alt = 30.48 ; |

Description: | Instrument suffered major oscillations in the signal. Working with Operator it was discovered that the Split System Air Conditioner was blowing directly on the Ozone detector. Water was condensing in the line. The air was redirected and the temperature setpoint raised. This reduced but didn't entirely eliminate the oscillations. |
