Model Change Bulletins

This area offers text (ASCII) files containing comprehensive information on all changes made to the computer code for the air quality models and related programs offered on this web site. These text files are identified as Model Change Bulletins (MCBs) and are available for reading on this homepage. A MCB with its associated number and julian date is the official identification of that version of the air quality model to which it refers. Changes to other than the computer code for a particular model are documented as amendments and are included within the MCB. There is one exception to this, the UAM model amendments are listed as separate documents(files). MCBs can be saved to ones computer by using the 'file save' command on your web browser. Click HERE or below to see a table listing all model/program names, their MCB numbers and effective julian dates. This table is identified as the Model Status Report.    "Yes" under the heading Documentation means there is a user's guide available in the User's Guide section for that model/program.
