Assimilated Ozone Field (North Pole)
The image shows
the near-real-time variation of the Assimilated Ozone Field over the North
Pole on a two-day basis. Measurements derive from SCIAMACHY and are
processed at TEMIS (Tropospheric Emission Monitoring Internet
The TM3-DAM model is used to produce global assimilated
ozone fields. The model produces global distributions of the total ozone
column in Dobson Units(DU). Global distributions are stored with a
resolution of 1.25 by 1.25 degree.
Data assimilation is a general
technique to combine measurements (which contain observation errors) with
models that describe the time evolution of the system.
