Measurement Data Unavailability

Expected operation interrupts, errors on instrument or spacecraft level and malfunctions of ground segment components can result in a discrepancy between the availability of measurement data ’as planned’ and ’as delivered’. The table below lists those intervals where no measurement data can be expected although the original planning of SCIAMACHY had foreseen routine or special operations in MEASUREMENT mode. Instrument and spacecraft anomalies can be found in the weekly Anomaly Reports.

The columns labelled ’ABS_ORB Start’ and ’ABS_ORB Stop’ indicate the number of the orbit including the UTC start/stop times of the event. The columns ’UTC - Start’ and ’UTC - Stop’ indicate the UTC times of the period with unavailable measurement data. Note that these times can be approximations only.

Select year: 2012 / 2011 / 2010 / 2009 / 2008 / 2007 / 2006 / 2005 / 2004 / 2003 / 2002
