| 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. |
