| Subject: | TWP/MICROBASE/C3 - Detection of precipitation is suspect |
|---|---|
| Affected Datastreams: | twpmicrobasepi2C3.c1 |
| Description | Microbase uses the CloudBasePrecipitation field from the twparscl1clothC3.c1 product to determine the occurrence of precipitation. The twparscl1clothC3.c1 CloudBasePrecipitation field is partially derived from the precip_mean field in the twpsmet60sC3.b1 product. DQR D060426.8 indicates there is a grounding issue with the optical rain gauge and the precip_mean values from twpsmet60sC1.b1 are suspect over this period. As a result, the values in the Microbase aqc_precip field could be suspect. Values of "14" to indicate precipitation in the Microbase aqc_liquid_water_content and aqc_liq_effective_radius fields could be suspect as well. Because we aren't certain when precipitation occurred, values of liquid_water_content and liq_effective_radius should be carefully evaluated during this period. |

| Subject: | TWP/MICROBASE/C3 - Incorrect detection of precipitation |
|---|---|
| Affected Datastreams: | twpmicrobasepi2C3.c1 |
| Description | Microbase uses the CloudBasePrecipitation field from twparscl1clothC3.c1 to determine the occurrence of precipitation. As noted in DQR D061220.35 for twparscl1clothC3.c1, the CloudBasePrecipitation is incorrect over this period due to a processing issue. As a result, the values in the Microbase aqc_precip field are incorrect. In addition, values of "14" to indicate precipitation in the Microbase aqc_liquid_water_content and aqc_liq_effective_radius fields are incorrect and should be ignored. Because we don't know when precipitation occurred, values of liquid_water_content and liq_effective_radius are suspect over this period. |
