AERMOD View - Using COARE Algorithms in AERMET
With the recent publication of the updated Guideline on Air Quality Models (Appendix W to 40 CFR Part 51), the U.S. EPA incorporated the Coupled Ocean-Atmosphere Response Experiment (COARE) algorithms into AERMET. The addition of COARE allows AERMET to seamlessly calculate boundary layer conditions for overwater marine environments, and the promulgation of COARE as regulatory default model option eliminates the need for alternative model demonstrations.

AERMOD View - Updates to Upper Air Processing with AERMET 24142
Several months ago, we published a Modeling Tip discussing important changes to processing upper air with the AERMET meteorological preprocessor. Since that time, the U.S. EPA released the 24142 versions of AERMET and other AERMOD modeling system components. This update expanded AERMET’s capabilities for handling the Integrated Global Radiosonde Archive (IGRA) upper air data format, and Lakes Software’s AERMET View Version 13.0 provides further optimization for users.

AERMOD View - National Land Cover Database Updates
In AERSURFACE is a non-regulatory component of the AERMOD air dispersion modeling system. The tool reads digital land cover data and objectively calculates surface characteristics for input to the AERMET meteorological preprocessor. Input to AERSURFACE comes from the USGS National Land Cover Database (NLCD) distributed through the Multi-Resolution Land Cover Consortium (MRLC).
