Community Modeling and Analysis System

Research and Development

Ongoing Research and Development | Model Development Guidelines

CMAS is keen on providing updates of current research efforts engaged by members of the community on the development and analysis of air quality modeling systems, including meteorology and emissions processing models. Research is focused on efforts to enhance the capability of air quality modeling systems to adequately address existing and future National Ambient Air Quality Standards (NAAQS). CMAS will provide leadership to bridge the gap between research and application needs by coordinating efforts among members of the community. Eventually, these research topics will lead to new research versions of CMAQ. Upon receiving new modules from the developers, CMAS will review the computational performance of the developed version and compare it to a benchmark case study provided by the developer to ensure accuracy, compilation, and compatibility among various computational platforms. CMAS will also review documentation that is provided by developers of the new material. CMAS will acknowledge the contribution of the developers of various modules.

CMAQ Review Process

Ongoing Research and Development

CMAS wants to hear about your CMAS-related research and/or model development! Please take a moment to provide us with some brief information about your CMAS-related research and/or model development, and we will post that information below. We also want your feedback on developing a vision for the next generation air quality modeling systems. Click on a title below to read more about the research.

  1. Efficient Radiative Transfer Calculations for Photolysis in CMAQ
  2. Extensions to chemically active coarse mode: Incorporation of sea-salt aerosols
  3. Incorporation of the Pleim-Xiu (PX) land surface model into the Weather Research and Forecasting (WRF) model

Model Development Guidelines

CMAS has compiled a set of guidelines for new code development, based on experience with portability testing of the CMAQ-MADRID code, developed by AER under an EPRI contract. The code has just been released in stand-alone mode (April 2004). Download instructions are available through Software Downloads.
