• Number of records in each DQI and MMAF_STAT category
  • MMAF_STAT: G, good data; t, missing NCEP temperatures below 22 hPa; T, missing NCEP temperatures below 100 hPa; M, missing tangent points; P, pointing anomaly; S, scan anomaly; B, bad data.
  • DQI (Data Quality Indicator): 4, good radiance fit/good radiances; 3, good radiance fit/some bad radiances; 2, bad radiance fit/good radiances; 1, bad radiance fit/some bad radiances; 0, anomaly/no fit.

• Number of spikes
• These are spikes in the retrieved O3_183 mixing ratios for records with MMAF_STAT = G/T/t and DQI = 4/2 (that is, good records with good radiances). Spikes are identified by comparison of their deviation from the monthly zonal mean with the rms variability (sigma) calculated in distinct 6 degree latitude bins.
  
• Total records this month with MMAF_STAT = G/T/t and DQI = 4: 32946
• Total records this month with MMAF_STAT = G/T/t and DQI = 4/2: 32955
• Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 5.0 sigma: 51 (fraction = 1.55e-03 )
• Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 4.0 sigma: 260 (fraction = 7.89e-03 )
• Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 4.0 sigma: 258 (fraction = 7.83e-03 )
