根据美国航天局利用多颗卫星上的仪器制作长期数据记录的方案，对来自一系列九台太阳后向散射紫外线（SBUV和SBUV/2）仪器的数据进行了再处理，以建立一个连贯的臭氧时间序列。来自Nimbus 4上的BUV仪器，Nimbus 7上的SBUV和NOAA 9，11，14，16，17，18和19上的SBUV/2仪器的数据涵盖1970-1972年和1979-2011年，用于创建长期数据集。其目标是建立一个臭氧地球科学数据记录系统，该系统可用于趋势分析和其他研究。为了创建这一臭氧数据集，对辐射率进行了调整，并用于重新处理九台仪器中每台仪器的全部数据记录。重叠期间的仪器间比较以及与其他卫星和地面仪器数据的比较被用来评价记录的一致性，并根据需要进行校准调整。8.6版处理中的其他改进包括使用Brion、Daumont和Malicet臭氧截面，以及从Aura OMI测量得出的云高气候学。验证的再处理臭氧表明，总柱臭氧是一致的布鲁尔/多布森网络的新的时间序列内约1%。与MLS、SAGE、探空仪和激光雷达的比较表明，平流层中各个层次的臭氧通常在5%以内。
Under a NASA program to produce long-term data records from instruments on multiple satellites, data from a series of nine Solar Backscatter Ultraviolet (SBUV and SBUV/2) instruments have been reprocessed to create a coherent ozone time series. Data from the BUV instrument on Nimbus 4, SBUV on Nimbus 7, and SBUV/2 instruments on NOAA 9, 11, 14, 16, 17, 18, and 19 covering the period 1970-1972 and 1979-2011 were used to create a long-term data set. The goal is an ozone Earth Science Data Recorda consistent, calibrated ozone time series that can be used for trend analyses and other studies. In order to create this ozone data set, the radiances were adjusted and used to reprocess the entire data records for each of the nine instruments. Interinstrument comparisons during periods of overlap as well as comparisons with data from other satellite and ground-based instruments were used to evaluate the consistency of the record and make calibration adjustments as needed. Additional improvements in this version 8.6 processing included the use of the Brion, Daumont, and Malicet ozone cross sections, and a cloud-height climatology derived from Aura OMI measurements. Validation of the reprocessed ozone shows that total column ozone is consistent with the Brewer/Dobson network to within about 1% for the new time series. Comparisons with MLS, SAGE, sondes, and lidar show that ozone at individual levels in the stratosphere is generally consistent to within 5%.
