Subject: | TWP/AOD/C3/C2/C1 - Reprocessing Notice (RID 1214) |
DataStreams: | twpmfrsraod1michC1.c1, twpmfrsraod1michC2.c1, twpmfrsraod1michC3.c1 |
Description: | See below for details of reprocessing that was completed on 20160204. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- For reasons not entirely understood, on or about Jan 1, 2013 the MFRSR AOD Value Added Product began to experience infrequent but serious data corruption issues. This is evident in the data files from TWP as irradiance fields, calibrations, and AODs taking nonsense values sometimes NaN, Inf, or other values orders of magnitude out of bounds with normal behavior. The behavior is sometimes abrupt with drastic changes observed from one day to the next, but not within a given day. This behavior was not reproducible when reprocessing on the development system. We have developed a new version of the MFRSR AOD Value Added Product using a different library suite and have confirmed successful reproduction of the existing product when the existing product was not corrupt, and consistent replacement of the corrupt periods with reliable results. |
