NO2 profile by ESA (last update: 16 May 2011)
validation summary	SCIAMACHY OL v3.01 NO₂ profile concentrations between 20 and 40km are in good agreement with those derived from HALOE measurements in combination with a photochemical model to account for diurnal changes. On average, the values are within 10-18% with larger uncertainties in the lower stratosphere (based on 2002-2003 data).
available data	Data from August 2002 to now are processed with OL 3.01. Data can be ordered via the ESA EO Principal Investigator Portal. Currently data are being reprocessed with the updated OL 5.01.
point of contact	ESA EO helpdesk
algorithm description	The Algorithm Theoretical Baseline Document for OL Version 5 can be found here
product details	The product format is described in the Envisat Products Specification Document. Lists of known issues are described in the OL product disclaimer and the NRT product disclaimer
