UARS DAYS: 0085 - 0124 ( 5 Dec 1991 - 13 Jan 1992 )

Plots for this month (pdf)
ASCII Data file of significant spikes for this month

File Creation Date: 29-Oct-2001 Spikecatcher revision date: 18-Oct-2001
Quality Indicator for Month (QIM) [for v500 . dat_1 ] = A
Further actions recommended: None.
Comments: There was some moon interference (for space view calibration) on several records of UARS days 101, 102, 103, and 124 (and these records are flagged as bad). UARS day 115 exhibited an unrecoverable software error, so that no Level 2/3 files exist.

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 HNO3 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: 50437
Total records this month with MMAF_STAT = G/T/t and DQI = 4/2: 50785
Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 5.0 sigma: 15 (fraction = 2.97e-04 )
Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 5.0 sigma: 101 (fraction = 1.99e-03 )
Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 4.0 sigma: 105 (fraction = 2.08e-03 )
Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 4.0 sigma: 222 (fraction = 4.37e-03 )
