2020 Finishes with Record Number of HYSPLIT runs.

The HYSPLIT server READY hosted over 2 million runs in 2020. The 2,055,410 simulations marks a 34% increase from the previous year. The success of online training during the summer of 2020 may have enabled new users to access the HYSPLIT tools and use them successfully.

In its first year of operation, the Locust swarm forecasting tool saw over 5000 runs, including a number of batch runs of multiple swarms. Primarily used by the UN Food and Agriculture Organization in the African subcontinent forecasts, the tool is still in its first year of operation. The tool forecasts the movement of locust swarms which destroy grains, grasses, and other food production capabilities in the region. Enhancements to the Locust forecasting tool are continuing in 2021, and the capabilities and usage of the tool is expected to increase in the future.
