UARS MLS PARAMETER: O3_205

UARS MONTH: 9202
UARS DAYS: 0157 - 0193 ( 15 Feb 1992 - 22 Mar 1992 )

• File Creation Date: 29-Oct-2001         Spikecatcher revision date: 18-Oct-2001
  
  
• Quality Indicator for Month (QIM) [for v500 . dat_1 ] = B
  
  
• Further actions recommended: None.
  
  
• Comments: There was some moon interference (for space view calibration) on several records of UARS days 185 and 186 (and these records are flagged as bad). UARS day 188 is a partial day because of UARS being off. A bad (spiky) orbit portion is not flagged (end of Uday 188). Probably related to instrument turn-on (see V4 comments), but this was mostly flagged with DQI=2 in V4, unlike V5.

  On day 188, poor O3_205 retrievals are evident for a short time just after instrument turn-on (less than an orbit of data), primarily in the upper stratosphere. Most of these were not flagged with DQI=2 in Version 5 data (although they were in Version 4 data).
  
  

• 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_205 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: 45139
• Total records this month with MMAF_STAT = G/T/t and DQI = 4/2: 45440
• Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 5.0 sigma: 54 (fraction = 1.20e-03 )
• Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 5.0 sigma: 102 (fraction = 2.24e-03 )
• Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 4.0 sigma: 165 (fraction = 3.66e-03 )
• Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 4.0 sigma: 241 (fraction = 5.30e-03 )
