HYSPLIT Prescribed Burn Capability Upgraded.
The prescribed burn capability employing BlueSky 4 from the U.S. Forest Service (USFS) was upgraded this week to several online HYSPLIT applications. The upgraded prescribed burn is available to NWS Weather Forecast Offices, registered HYSPLIT users, and public users through several software systems intended for respective groups of users.
BlueSky 4 is not a model, but it connects models together and makes them easy to run in combination. It is a culmination of USFS research on fire ecology and combustion and it estimates fire emissions using fuel loadings from a database, modeling combustion and heat released, and computing emission factors.
