All these rumors are impossible to reconcile in just one new MacBook Air, but maybe not if Apple ships two distinct models. AppleInsider reports this will be the case, with the 11.6-inch model “a more aggressively priced option.” Further refinements will include a button-less trackpad, and the elimination of the port door housing the USB and Mini DisplayPort. Both models will continue to be extremely thin.
Cult of Mac now cites “independent confirmation” of two traditional 13.3-inch MacBook Air models, and a new 11.6-inch model. The 13.3-inch form factor will not be as “curvy,” as the current Macbook Air, but “boxier, like the iPhone 4 design.” Although the new MacBook Air will still have an aluminum unibody enclosure, it will weigh less than the current model’s three pounds.
This website is maintained by EPA's Air Quality Modeling Group (AQMG). The AQMG conducts modeling analyses to support policy and regulatory decisions in the Office of Air and Radiation (OAR) and provides leadership and direction on the full range of air quality models and other mathematical simulation techniques used in assessing control strategies and source impacts. Documentation and guidance for these air quality models can be found on this website, including downloadable computer code, input data, and model processors.
Air Quality Models - Provides descriptions and documentation for three types of air quality models: dispersion, photochemical, and receptor models. Also provided with the dispersion modeling section are source code and associated user's guides and documentation for preferred/recommended models, screening models, and alternative models. Modeling Applications and Tools - Provides more detailed information on modeling analyses AQMG has conducted to support policy and regulatory decisions in OAR including assessment of control strategies and source culpability. In addition, this site provides access to EPA developed tools for use in State Implementation Plan (SIP) demonstrations and other air quality modeling assessments.
