  2. AERSCREEN WORKGROUP PROGRESS REPORT • WORKGROUP GOAL: Develop an AERMOD screening procedure (AERSCREEN) that will provide concentrations as conservative as predicted by AERMOD in refined mode and allow quick run time. • CURRENT PROGRESS: AERSCREEN v1.6 (Beta) has been developed and is currently being tested. This version contains all desired elements (i.e. including wake, terrain and averaging period ratios) for point sources. The documentation is being developed. We plan to release this version within the next several weeks.
