Develop integrated data products combining assimilation model
results, ground-based data and remote sensing fields
Improve satellite retrievals
Analyze long-term trends in existing model results and check consistency
with trends in observations
Constrain budgets
Evaluate global & regional models with GEOmon data
Optimize measurement networks through comparisons between observed
and modelled tracer distributions
