Processing of GOME-ROSE has been completed for the time period 1996-2003. 4D-VAR analysis using SACADA is ongoing. Completion is expected for the end of 2008. MIPAS reanalyses for 2003-2004 will follow early 2009.
Data file format
Daily analyses are archived in NetCDF file format.
This format is self-explanatory. We recommend NASA's Panoply tool to read the inventory and plot the data.
Filenames are of the form, e.g., GOME_3DS_O3base_19970713.nc, where 'GOME' identifies the instrument (currently only GOME or MIPAS), '3DS' the assimilation model type SACADA. ROSE/DLR analysis are indicated by '3DR'.
'O3base' means analysis of base parameters. 'O3plus' identifies files that give additional information on chemistry (see below).
The date of analysis is in Year-Month-Day (YYYYMMDD) format. Valid analysis time is 12:00 GMT.
