Subject: | TWP/MWR/C2 - Excessive wet_window flags |
DataStreams: | twpmwrlosC2.b1, twpmwrtipC2.a1 |
Description: | The wet_window flag is set high more than expected from the measured value of liquid water path. This may be caused by dew or, if the heater sensivity is slightly misadjusted, by the diurnal variation in ambient temperature. The "wet_window" flag is an indicator of moisture on the MWR window which invalidates the measurements of precipitable water vapor and liquid water path. Sometimes this flag can be incorrectly set high or low if the heater sensivity is slightly misadjusted. The heater adjustment is a resistive device that is dependent on ambient temperature. Another indicator of moisture on the window is unreasonably high ( > 3*liquid_retrieval_rms_accuracy ) values of "liq". |

Subject: | TWP/MWR/C1 - wrong azimuth |
DataStreams: | twpmwrlosC1.b1 |
Description: | The MWR was initially installed at an azimuth angle defined as 180 degrees but the value in the configuration file was not changed from the default of 0 degrees. In examining photos taken during the installation of the AWS tower, I noticed that the MWR was rotated opposite the normal orientation. The value in the configuration file was changed to reflect the actual azimuth of the instrument. |
