Subject: | TWP/MWR/C1 - Rain events not flagged |
---|---|
Affected Datastreams: | twpmwrlosC1.b1 |
Description | On some occasions the rain flag did not flag data during likely rain events. Users should carefully examine the data to ensure that they are not contaminated by rain. Also examine the brightness temperature qc variables. |

Subject: | TWP/MPLCMASK/C1 - Reprocess: Backscatter signals not set to missing when beam blocked |
---|---|
Affected Datastreams: | twp30smplcmask1zwangC1.c1 |
Description | The backscatter signals are flagged as missing when the beam is blocked. For the historical data, this functionality was not implemented (when the VAP uses MPL as input). This flag is not very reliable since it is based on the signal strength during the beam blocked conditions. |

Subject: | TWP/MWR/C1/C2 - Sun in the field of view |
---|---|
Affected Datastreams: | twpmwrlosC2.b1 |
Description | Every day between around noon local time (usually between 1 and 2 AM UTC time) there is an increase in the brightness temperatures due to the sun in the field of view of the radiometer. The effect lasts less than an hour around local noon (usually between 1 and 2 AM UTC time). The effect appears as a smooth increase and decrease in brightness temperature. |
