CATT and FASTNET are inter-RPO projects that provide tools for analyzing aerosol and trajectory data. They have been integrated into the DataFed.Net infrastructure, which provides a variety of web-based applications and data catalogs for accessing, viewing, analyzing, and interpreting fast, current, and slow aerosol and meteorological data. This document provides an overview of the types of data and analysis tools available through DataFed.Net for studying aerosol events and transport patterns.
