Ozone Assimilation Monitoring

Since TOMS ozone data is not operationally assimilated, this data provides an independent check of GDAS ozone analyses and GFS forecasts. Comparisons of TOMS and operational (GFS) total ozone fields are found by clicking below:

GFS daily analyses 5-day forecasts
PRX daily analyses 5-day forecasts
