ACX/OZONE/M1 - Data noisy while ship is under way
DataStreams:acxaosozoneM1.a1
Description:
Data is noisy at high frequency while ship is under way. Regular daily calibrations show 
the accuracy is correct, only the noise is severe (+/- 5-10 ppbv).
Measurements:acxaosozoneM1.a1:
  • Ozone concentration(ozone)

ACX/OZONE/M1 - Reprocess: acxaosozoneM1.a1 to acxaoso3M1.a1
DataStreams:acxaosozoneM1.a1
Description:
The aosozone.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:acxaosozoneM1.a1:
  • Ozone concentration(ozone)
  • North latitude(lat)
  • base_time
  • time_offset
  • ozone_bench_temp
  • Ozone pressure(ozone_pressure)
  • East longitude(lon)
  • Altitude above mean sea level(alt)
  • time
