Subject: | PYE/MPL/M1 - wrong temperature calibration |
DataStreams: | pyemplM1.a1 |
Description: | Wrong calibration coefficients were applied to the temperature values. These are engineering housekeeping data only. The scientifically relevant measurements were unaffected. |

Subject: | PYE/MWRP/M1 - Bias in Ground Relative Humidity Measurement |
DataStreams: | pyemwrpM1.00, pyemwrpM1.b1 |
Description: | On June 17 2005, the MWRP was re-installed at PYE after the Super Blower was replaced by the old style dew blower. The relative humidity ground sensor in the dew blower is not as accurate. This resulted in a negative relative humidity bias of about 5.9 %. In other words the MWRP sensor was underestimating the relative humidity. The bias was determined by comparing MWRP measurements with SMET and radiosonde measurements. The MP.cfg file for the MWRP was changed to reflect this bias on 09/02/2005 and will take effect on 09/03/2005 0000 GMT |

Subject: | PYE/MPL/M1 - Erroneous temperatures |
DataStreams: | pyemplM1.a1 |
Description: | The temperature readings for the laser, detector, and instrument are erroneous. Incorrect calibration factors; data should not be used. This time period is prior to the official start of the PYE deployment. |
