Subject: OLI/ALL/M1 - Power Outage
Affected Datastreams: oliaosnephwet1mM1.b1
Description OLI suffered from a prolonged power outage. The instruments were brought back up over the course of 3/9 so the end date will be different for each instrument. Any problems with the instruments after being brought back online will be covered by separate DQRs.

Subject: OLI/MWR3C/M1 - Reprocessed and Corrected: Excessive noise
Affected Datastreams: olimwr3cM1.b1
Description DATA REPROCESSED and CORRECTED: There are occasional jumps in the brightness temperatures that are due to noisy voltages during the gain calibration. The ingest was updated to account for this and data reprocessed. The data were archived in August 2017. 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::mwr3c/ffac::oli.M1 ORIGINAL DQR CATEGORY: Yellow - Suspect REPROCESSED and CORRECTED DATA ARCHIVED: 2017-08 REPROCESS IDENTIFICATION NUMBER: RID 1609 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- There are occasional jumps in the brightness temperatures that are due to noisy voltages during the gain calibration --------------------------------------------------- --- ORIGINAL DQR SUGGESTIONS --- --------------------------------------------------- Wait for reprocessed data
