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 ] = B
Further actions recommended: None.
Comments: There was some moon interference on several records of UARS days 363 and 364 (and these records are flagged as bad). NCEP stratospheric data (northern hemisphere) were missing for UARS day 351.

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: 49623
Total records this month with MMAF_STAT = G/T/t and DQI = 4/2: 50032
Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 5.0 sigma: 58 (fraction = 1.17e-03 )
Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 5.0 sigma: 124 (fraction = 2.48e-03 )
Total records with MMAF_STAT = G/T/t and DQI = 4 with at least one spike greater than 4.0 sigma: 167 (fraction = 3.37e-03 )
Total records with MMAF_STAT = G/T/t and DQI = 4/2 with at least one spike greater than 4.0 sigma: 275 (fraction = 5.50e-03 )
