US EPA Releases Draft AERSURFACE Update for Public Comment

On February 21, the US EPA announced release of AERSURFACE version 19039_DRFT, a draft update to the AERSURFACE preprocessor which calculates surface characteristics from digital land use data for input to AERMET. The updated executable and documentation were published on the SCRAM website.

A full list of changes for each model can be found on the Draft AERSURFACE web page. Changes include:

  • Ability to process more recent United States Geological Survey (USGS) National Land Cover Database (NLCD) products including 2001, 2006, & 2011 land cover data.
  • Supplemented the above with concurrent percent impervious and percent tree canopy data where available.
  • An updated input control file format similar to the one used in AERMOD, AERMET, & AERMAP.
  • Inclusion of a new surface roughness length calculation method.

EPA is seeking informal public review, testing, and comment on the updates. Specific items of interest include reference lookup tables used to compute surface characteristics, implementation of impervious & tree canopy data, and implementation of the new surface roughness length calculation method. Comments are due no later than Monday, April 22, 2019.

An EPA-hosted webinar on the changes will be conducted on Thursday, April 4 from 2-3PM EDT. Refer to the EPA SCRAM website for more information.

Lakes Environmental's team is hard at work incorporating these updates into AERMET View. Be on the lookout for an email from Lakes Environmental announcing the next AERMOD View release upon its availability.
