In this chapter, you will learn to: Understand AIR2GIS Understand naming conventions Understand who should use this manual Understanding AIR2GIS U.S. Environmental Protection Agency (U.S. EPA) Region 6 developed AMP under the Regional Air Impact Modeling Initiative (RAIMI) to consolidate the large plot files generated by each ISCST3 run into a single file for each source to input into the Risk-MAP Node Array Index Table. The core capability of AIR2GIS provides the air modeler with a tool to prepare source-specific output files from the ISCST3 air model plot files. As each source may have up to four air model runs, one for each contaminant phase, consolidating the run results into a single file provides for logistically tracking and simplified integration of air model results into Risk Management Analysis Platform (Risk-MAP) to support further analysis. The air model generates air parameter values at each grid node (approximately 7,500-8,000 nodes) with a discrete value for the one-hour average air concentration for use in acute risk assessment, and for the annual average air concentration, dry deposition and wet deposition for use in chronic risk assessment. AIR2GIS addresses the four potential phases of the emitted constituents, including volatile vapor, particle, particle-bound and mercury vapor phases. For each contaminant phase modeled, ISCST3 outputs the air parameter values into two separate plot files, a one-hour and an annual, for each source modeled. AIR2GIS extracts the sixteen air parameter values from the eight air model plot files based on grid node location and merges them into a single air parameter value file for each source. This file for each source, referred to as the A2G' file, is imported into Risk-MAP to support further analysis. Introduction ------- TOC AIR2GIS User's Manual Naming Conventions AIR2GIS must read air model results from numerous sources and create a concatenated air parameter value file. The file naming convention is based on the unique source ID assigned to each source in the inventory. The air model runs are named for the unique source ID, with extensions identifying the file type. The following table shows the naming conventions for each phase: Phase Plotfile Extension vapor annual .vpa vapor one-hour ,vp1 particle annual ¦PPa particle one-hour ,pp1 particle-bound annual .bpa particle-bound one-hour ,bp1 mercury vapor annual .hpa mercury vapor one-hour ,hp1 Who Should Use This Manual This manual is intended for air modelers experienced in performing ISCST3 air dispersion modeling.
