Model Intercomparison

1. WMO SDS-WAS: Compared Dust Forecasts and Forecast Evaluation

Products from different numerical prediction models are represented at a common geographical domain, which is intended to cover the main source areas, as well as the main transport routes and deposition zones in the region.  Products with lead time up to 72 hours are represented using common color palettes.

Then, model forecasts are compared with AERONET observations for selected dust-prone stations.

• Multi-model Products
• Forecast Evaluation
• Guidance for forecasters

2. AEROCOM Model Intercomparison

	AEROCOM Model Intercomparison

Stored model results are compared against observations using AEROCOM tools.

The AEROCOM project is an open international initiative of scientists interested in the advancement of the understanding of the global aerosol and its impact on climate. A large number of observations (including MODIS, POLDER, MISR, AVHHR, SEAWIFS, TOMS, AERONET and surface concentrations) and results from more than 14 global models have been assembled to document and compare state of the art modeling of the global aerosol. A common protocol has been established and models are asked to make use of the AEROCOM emission inventories for the year 2000 and preindustrial times. Results are documented via interactive websites, which give access to 2D fields and standard comparisons to observations. Regular workshops are held to discuss findings and future directions.
