Subject:	SGP/AOD/ALL - Reprocessed and Corrected: airmass field is incorrectly set to -1 when failing QC.
Affected Datastreams:	sgpmfrsraod1michE12.c1
Description	DATA REPROCESSED and CORRECTED: The qc_airmass field indicates that the values in the airmass field are set to -9999, the missing value, when qc_airmass = 1 (the QC bit 1 was tripped). In reality, the values were set to -1 and will not be filtered out properly by programs that automatically remove missing values. The processing code creating this data has been modified and the data reprocessed and archived in December 2015. Please retrieve the reprocessed data for use in your analysis. You may find these data using the ARM Discovery tool at the following link: http://www.archive.arm.gov/discovery/#v/results/s/finst::aod/fsite::sgp/ffac::sgp ORIGINAL DQR CATEGORY: Transparent (Does not affect quality) REPROCESSED and CORRECTED DATA ARCHIVED:2015-12 REPROCESS IDENTIFICATION NUMBER: RID 1286 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The qc_airmass field indicates that values in the airmass field are set to -9999, the missing_value, when qc_airmass = 1 (QC bit 1 has tripped). In reality, the values are set to -1 and will not be filtered out by programs that automatically remove missing values. This will be fixed in a future reprocessing task.

Subject:	SGP/MFRSR/E31 - Shadowband bent by severe storm
Affected Datastreams:	sgpmfrsrE31.a0
Description	Severe storms and a tornado passed very near the E31 facility on 4/15. Something happened that caused the data covered by this DQR to look very strange. The instrument must have physically shifted. Standard alignment procedures on 4/24 resolved the issue. The site ops technician found the shadowband was bent out of shape by the storm.

Subject:	SGP/AOD/ALL - Reprocessing Notice (RID 1212)
Affected Datastreams:	sgpmfrsraod1michE3.c1
Description	See below for details of reprocessing that was completed on 20160127. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- For reasons not entirely understood, on or about Oct 28, 2012 the MFRSR AOD Value Added Product began to experience infrequent but serious data corruption issues. This is evident in the data files from SGP 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.
