This page provides an overview of the completeness of the SCIAMACHY consolidated Level 0 dataset on which the full-mission reprocessing activities are based.
The SCIAMACHY dataset starts on 02 Aug 2002 (orbit 2204, start of in-flight operations) until 08 Apr 2012 (last orbit acquired 52867, end of SCIAMACHY operational phase). The following tables summarize, for each of the 10-years of the ENVISAT mission, statistics of Level 0 products availability: the number of orbits executed by ENVISAT, the number of orbits for which a unique SCIAMACHY consolidated Level 0 product (cL0) is available, and the number of not recoverable orbits (gaps) either for missing orbits when SCIAMACHY was fully operational but no cL0 product had been produced (i.e. error in data downlink or processing) or for phases when SCIAMACHY was in measurement idle (i.e. instrument or platform anomalies, orbit control maneuvers - OCM).
Statistics are provided with respect to ENVISAT executed orbits (Table 1), and with respect to SCIAMACHY actual measurement orbits (Table 2). Note that SCIAMACHY Level 0 products are not distributed to users.
More details are accessible on the SOST web page.

Table 1 – Statistics for SCIAMACHY consolidated Level 0 data availability. The total number of SCIAMACHY available products is compared to the number of ENVISAT executed orbits giving an overview of the overall instrument performance. Gaps comprise all possible causes.
