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	ozone (Ozone concentration) lat (North latitude) ozone_pressure (Ozone pressure) lon (East longitude) time (Time offset from midnight) time_offset (Time offset from base_time) base_time (Base time in Epoch) alt (Altitude above mean sea level) ozone_bench_temp (Ozone bench temperature)

Subject:	SGP/TRACEGAS/S01 - Instrument
Affected Datastreams:	sgpaospsaprS01.a0
Description	Improper start up following a power failure. Computers came back up but instruments did not restart (by design for Oliktok). Daily checklists not compiled this period (weekend).
Measurements	diagnostic_voltage_mb_minus_3p3 (Diagnostic -3.3 volts at motherboard) lat (North latitude) ozone (Ozone concentration) diagnostic_voltage_mib_24 (Diagnostic +24 volts at measurement interface board) temperature_compensation_state (Temperature compensation state) range (Instrument range setting) alt (Altitude above mean sea level) diagnostic_voltage_mib_15 (Diagnostic +15 volts at measurement interface board) averaging_time (Instrument averaging time) diagnostic_voltage_mb_3p3 (Diagnostic +3.3 volt at motherboard) pressure_compensation_state (Pressure compensation state) diagnostic_voltage_mib_5 (Diagnostic +5 volts at measurement interface board) diagnostic_voltage_mib_3p3 (Diagnostic +3.3 volts at measurement interface board) ozone_pressure (Ozone pressure) lon (East longitude) diagnostic_voltage_mb_24 (Diagnostic +24 volts at motherboard) diagnostic_voltage_mb_15 (Diagnostic +15 volts at motherboard) diagnostic_voltage_mb_5 (Diagnostic +5 volts at motherboard) time_offset (Time offset from base_time) time (Time offset from midnight) diagnostic_voltage_mib_minus_15 (Diagnostic -15 volts at measurement interface board) base_time (Base time in Epoch) ozone_bench_temp (Ozone bench temperature)

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_pressure (Ozone pressure) ozone_bench_temp (Ozone bench temperature)

Subject:	SGP/S01 - Tower inlet not operational
Affected Datastreams:	sgpaosso2S01.a1
Description	Inlet not operational in order to change met sensor.
Measurements	diagnostic_voltage_mb_minus_3p3 (Diagnostic -3.3 volts at motherboard) ozone (Ozone concentration) ozone_pressure (Ozone pressure) averaging_time (Instrument averaging time) diagnostic_voltage_mib_24 (Diagnostic +24 volts at measurement interface board) diagnostic_voltage_mb_3p3 (Diagnostic +3.3 volt at motherboard) pressure_compensation_state (Pressure compensation state) diagnostic_voltage_mb_24 (Diagnostic +24 volts at motherboard) diagnostic_voltage_mib_5 (Diagnostic +5 volts at measurement interface board) temperature_compensation_state (Temperature compensation state) range (Instrument range setting) diagnostic_voltage_mib_3p3 (Diagnostic +3.3 volts at measurement interface board) diagnostic_voltage_mib_minus_15 (Diagnostic -15 volts at measurement interface board) diagnostic_voltage_mb_15 (Diagnostic +15 volts at motherboard) diagnostic_voltage_mib_15 (Diagnostic +15 volts at measurement interface board) diagnostic_voltage_mb_5 (Diagnostic +5 volts at motherboard) ozone_bench_temp (Ozone bench temperature)
