The Total Column Level-3 Product

The total column BrO level-3 Product completes the BrO Level-2 Product with a collection of maps (monthly and daily maps) in three available projections (Northern hemisphere, Southern hemisphere and global projection) and with time series over pre-defined stations known for carrying on BrO measurements.

Last GOME processing: Reprocessing of the whole GOME data set in November 2003. See the GOME BrO retrieval page for further information.
Last SCIAMACHY processing:

The 2003-2010 data set has been reprocessed in 2011 and then completed until January 2012
For further information on the DOAS technique used to retrieve the slant columns, see the Algorithm Description Document.
For a better description of the Level-3 product, see the Product Specification Document.

Last GOME2 processing:

Maps from 2007 to 2010 are available. For Level-2 process, please contact Nicolas Theys.

Maps are created from pre-calculated grids (resolution : 0.5° in latitude, 1° in longitude for GOME, 0.5° in latitude, 0.5° in longitude for SCIAMACHY) using add-ons developed in Matlab, a language for technical computing, including high-performance graphics and mapping facilities.
The length of the individual pixels and the sphericity of the earth are taken into account to distribute and weight the BrO Vertical Columns (BrO VCD) in the different graticules of the grid crossed by the pixel.
The colorbar has been adjusted in order to bring the tropospheric BrO to the fore.

Monthly maps are calculated by averaging data over a complete month
