all days of a month
Access the archive of Assimilated Ozone Fields based on OMI
measurements by selecting a date in the menu on the left.
Three images of the selected date for 12h UTC will appear here:
a global image, and polar views of the south pole and north pole.
Data is available between
01 October 2004 and 31 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.
