System of Systems Tools
- Program to Assist in Tracking Critical Habitat (PATCH) - This is a spatially explicit, individual-based, life history simulator designed to project populations of territorial terrestrial vertebrate species through time. PATCH is ideal for investigations involving wildlife species that are mobile habitat specialists.
- Internet Geographical Exposure Modeling System (IGEMS) - Iincludes models and data for ambient air, surface water, soil, and ground water, and makes the models much easier to use than their stand-alone counterparts.
- Multi-Chamber Concentration and Exposure Model. (MCCEM) - Estimates average and peak indoor air concentrations of chemicals released from products or materials in houses, apartments, townhouses, or other residences. [Metadata]
- Wall Paint Exposure Assessment Model (WPEM) - This model estimates the potential exposure of consumers and workers to the chemicals emitted from wall paint which is applied using a roller or a brush. [Metadata]
- Dietary Exposure Potential Model - A Model Using Extant Food Databases to Estimate Dietary Exposure to Chemical Residues Latest Version 5.0 Released April, 2003. [Metadata]
- Council for Regulatory Environmental Modeling (CREM) - Database containing an inventory of EPA's environmental models. [Metadata]
- AQUATOX - Freshwater ecosystem simulation model which predicts the fate of various pollutants, such as nutrients and organic chemicals, and their effects on the ecosystem, including fish, invertebrates, and aquatic plants. [Metadata]
