MLS V4

UARS MLS PARAMETER: O3_205

UARS MONTH: 9209
UARS DAYS: 0415 - 0444 ( Oct. 30, 1992 - Nov. 28, 1992 )

Plots for this month
ASCII Data file of significant spikes for this month

Inspection Date: 30-Dec-1996
Quality Indicator for Month (QIM) [for v422] = B
Further actions recommended: None.
Comments: This month contains a somewhat unusual number of spikes in the profiles (albeit still a small number as a fraction of the total profiles); this leads to a number of profiles (generally those with largest spikes) with a data quality indicator (DQI) value of 2, rather than 4. The profiles with spikes often occur in the 0 to 30 N latitude range.

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.
