UARS MLS PARAMETER: TEMP

UARS MONTH: 9205
UARS DAYS: 0265 - 0305 ( Jun. 2, 1992 - Jul. 12, 1992 )

• Inspection Date: 27-Jan-1997
  
  
• Quality Indicator for Month (QIM) [for v422 ] = A
  
  
• Further actions recommended: None.
  
  
• Comments: A solar drive anomaly aboard UARS at the beginning of this UARS month led all instruments to be turned off for significant portions of this time period; however, a 24 hr 'composite day' can be obtained from UARS day 264 (yaw day) and UARS day 265, for an early look south. MLS was turned off from late on UARS day 265 (June 2) to late on UARS day 277 (June 14). There was some moon interference on several records of UARS days 279, 280, and 281 (and these records are flagged as bad). After this, the MLS scan was stopped on several days for up to several hours (UARS days 282, 286-289, 292, 301, 302). In addition, the 183 GHz radiometer system (which generates data for H2O and O3_183) was off completely from late on UARS day 282 to late on UARS day 302; on these days, band 3 was also off (with a minor impact on ClO data). Finally, NCEP data (both hemispheres) were missing for UARS day 282 (this has a minor impact on MLS retrievals).
  
  
• 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 TEMP 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: 34788


• There were no spikes greater than 5 sigma.
• Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 4 sigma: 41 (fraction = 1.18e-03 )
