SBUV/Nimbus-07 Ozone (O3) Profile and Total Column Ozone Monthly L3 Global 5.0deg Lat Zones V1 SBUVN07L3zm at GES DISCEntry ID: GES_DISC_SBUVN07L3zm_V1
Abstract: The Solar Backscattered Ultra Violet (SBUV) from Nimbus-7 Level-3 monthly zonal mean (MZM) product (SBUVN07L3zm) is derived from the Level-2 retrieved ozone profiles. Ozone retrievals are generated from the v8.6 SBUV algorithm. A Level-3 MZM file computes zonal means covering 5 degree latitude bands for each calendar month. For this product there are 139 months of data from November 1978 through ... May 1990. There are a total of 36 latitudinal bands, 18 in each hemisphere. Profile data are provided at 21 layers from 1013.25, 639.318, 403.382,254.517, 160.589, 101.325,63.9317, 40.3382, 25.4517, 16.0589, 10.1325, 6.39317,4.03382, 2.54517, 1.60589, 1.01325,0.639317, 0.403382, 0.254517, 0.160589 and 0.101325 hPa (measured at bottom of layer). NOTE: Some profiles have 20 layers and do not report the top most layer. Mixing ratios are reported at 15 layers from 0.5, 0.7, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 7.0, 10.0, 15.0, 20.0, 30.0, 40.0 and 50.0 hPa (measured at middle of layer).
The MZM product averages retrievals that meet the criteria for a good retrieval as determined by error flags in the Level 2 data. A good retrieval is defined as satisfying the following conditions:
1) Profile Error Flag = 0 or 1 (0 = good retrieval; 1 = solar zenith angle > 84 deg.)
2) Total Error Flags = 0, 1, 2 or 5 (0 = good retrieval; 1 = not used; 2 = solar zenith angle > 84 deg; large discrepancy between profile total and best total ozone)
NOTE - Total error flag = 5 is anomalously applied at high latitudes and high solar zenith angle where B-Pair total ozone estimate is not as reliable as profile under these conditions. This error flag may be removed in future version of algorithm.
The zonal means computed for each month are screened according to the following statistical criteria:
1) number of good retrievals for the month greater than or equal to 2/3 of the samples for a nominal month.
2) mean latitude of good retrievals less than or equal to 1 degree from center of latitude band.
3) mean time of good retrievals less than or equal to 4 days from center of month (i.e., day = 15)

Quality A lack of coverage typically but not always in the center of the continent has been a characteristic in the composites. With the strict limits on qualified data to be input to a composite, and with no older data used or any other “synthetic” creation of data, regions without coverage do result. This “black hole” region has been reduced in recent years due to improvements in satellite coverage and observations, but still remains as a limitation of the composite.
Access Constraints The Arctic composites are available at no cost. However, we request that any use of the data acknowledged as from: Space Science and Engineering Center, University of Wisconsin-Madison (or SSEC, UW-Madison if short on space). This project is funded by the Arctic Natural Science Program, Office of Polar Programs, National Science Foundation Grant ARC-0713843.
