Subject: | SGP/DISDROMETER/C1 - False reports of precip |
DataStreams: | sgpdisdrometerC1.b1 |
Description: | A number of days during this period show indications of rain on dry days. This occurred during windy periods when vibrations of the splash guard resulted in many small drops being recorded. The splash guard has been removed and the Instrument Handbook has been updated with a larger section describing this issue (Section 5.3 on known problems). |

Subject: | SGP/MERGESONDE/C1 - Reprocess: Precip data incorrect |
DataStreams: | sgpmergesonde1maceC1.c1 |
Description: | All precip values are incorrectly reported during the period: From 20060101-20101231 all precip values are incorrectly reported as missing, or -9999. From 20110101-present all precip values are reported as 0 even though the qc_precip variable flags the data as missing, or -9999. The precipitation data from the co-located surface met station were not actually missing, but the MERGESONDE VAP did not properly ingest these data. While the 0 precip values reported after 20110101 in MERGESONDE may be correct on days with no precip, they are not actually tied to the measurements from the co-located rain gauge and are due to a VAP software error. To correct this issue, the MERGESONDE software will need to be corrected so the data can be reprocessed. Because precip is a secondary variable in MERGESONDE, this issue is considered low priority and the VAP will not be reprocessed until a sufficient number of issues in the VAP have been identified. |
