Cloud top height by ESA (last update: 16 May 2011)
validation results SCIAMACHY OL 3.01 cloud top height correlates well with FRESCO sc-v5 cloud height (R=0.87) but is on average 1.2km higher. The spread in the difference is about 1.9km. About 15% of the cloud height data are clipped to the lower limit of 1km. No validation with independent correlative measurements has been reported yet.
available data Data from August 2002 to April 2012 processed with OL v5.02 can be ordered via the ESA EO Principal Investigator Portal. Currently data are being reprocessed with the updated OL 5.01.
