This user's guide provides both an operational and theoretical summary of the MATHEW/ADPIC transport and diffusion models and supplemental codes needed to execute these models. The acronym, MATHEW, comes from Mass-Adjusted THRee-dimensional Wind field. ADPIC stands for Atmospheric Diffusion Particle-In-Cell model. These models calculate air concentration and ground deposition on a regional scale (up to 200 km) from continuous or instantaneous point sources. MATHEW is a three-dimensional meteorological data-adjustment model which supplies ADPIC with mean wind fields that are mass-consistent and representative of the available meteorological measurements. The bottom boundary in this model is determined by grid cell estimates of the actual topographic features of a given site and its environs, which can play a very important role in defining or modeling regional-scale patterns. ADPIC is a three-dimensional, particle-in-cell transport and diffusion code capable of calculating the time-dependent dispersion of inert or radioactive air pollutants. An overview of MATHEW/ADPIC and the support routines is included. A complete technical formulation of each code is found in Section 2. Section 3 provides a user's guide to each code.
