all days of a month
Access the archive of Assimilated Ozone Fields based on OMI
measurements by selecting a year and month in the menu on the left.
The images of all days in the selected month for 12h UTC will appear
here for the selected view: a global view, or views of the south pole
and north pole.
Data is available between
01 October 2004 and 09 March 2021.
The data assimilation program (TM3-DAM) does not only make
the assimilated field but it also gives a details model forecast
error estimate.This estimated error will in general be largest in
areas from which no OMI data is available.
If the forecast error is larger than 25 DU in a grid cell, the ozone
column value for that cell is not plotted in the graphs; instead, the
grid is marked grey.
