Subject:	SGP/OZONE/S01 - Filter not changed
Affected Datastreams:	sgpaoso3S01.a1
Description	Filter not changed. Pressure low and response to calibrations increased. The time before the filter change is considered suspect.
Measurements	ozone (Ozone concentration) ozone_bench_temp (Ozone bench temperature) ozone_pressure (Ozone pressure)

Subject:	SGP/OZONE/S01 - Reprocessed and Corrected: sgpaosozoneS01.a1 to sgpaoso3S01.a1
Affected Datastreams:	sgpaoso3S01.a1
Description	DATA REPROCESSED and CORRECTED: The aosozone.a1 data was renamed to aoso3.a1. In addition to the rename, we added data from raw data columns that were originally not included. These additional columns will be used in subsequent downstream processing. The data were archived February 2017. Please retrieve the reprocessed data for use in your analysis. ORIGINAL DQR CATEGORY: Transparent (Does not affect quality) REPROCESSED and CORRECTED DATA ARCHIVED:2017-02 REPROCESS IDENTIFICATION NUMBER: RID 1496 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The sgpaosozoneA01.a1 data is being renamed to aoso3.a1. In addition to the rename, we are adding data from raw data columns that were missed. These additional columns will be used in subsequent downstream processing.
Measurements	lon (East longitude) time_offset (Time offset from base_time) ozone (Ozone concentration) base_time (Base time in Epoch) ozone_bench_temp (Ozone bench temperature) ozone_pressure (Ozone pressure) lat (North latitude) alt (Altitude above mean sea level) time (Time offset from midnight)
