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/SMET/C2 - Negative rainfall rates |
DataStreams: | twpsmet60sC2.b1 |
Description: | Due to limitations of the Zeno dataloggers all voltage measurements from the optical rain gauge (ORG) were converted to rainfall rates. This resulted in negative values for rain rates. Any value below 0.10 mm/hr should be considered to be 0 mm/hr. New dataloggers alleviated this problem. |

Subject: | TWP/SMET/C2 - Reprocess: Barometric Data Changed from hPa to kPa |
DataStreams: | twpsmet60sC2.b1 |
Description: | Barometric pressure data was converted from hPa to kPa in order to standardize the measurement units among ARM sites and to conform to accepted standard units determined by the scientific community. |

Subject: | TWP/SMET/C2 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC2.b1 |
Description: | A tipping bucket rain gauge was added to the TWP.C2 SMET suite of instruments on 20061129. Effective 20060926, two new variables (count and rain amount) were added to the end of the twpsmet60sC2.b1 datastream. Between 9/26 and 11/29, the data for these two variables are filled with zeros. Users should not use the data during this period as the zeros are not representative of the rain fall at the site. When reprocessing of this datastream occurs these variables will be added for the 19981021-20060926 and data from 19981021-20061129 will be filled with -9999 (missing). |
