Generate fertilizer application input for CMAQ bi-directional NH3 modeling
The Fertilizer Emission Scenario Tool for CMAQ (FEST-C) system is used to simulate daily fertilizer application information using the Environmental Policy Integrated Climate (EPIC) model for a defined CMAQ domain. This EPIC output information is a required input for CMAQ bi-directional NH3 modeling. The FEST-C contains two major components - a Java-based interface and EPIC modeling system. The FEST-C interface integrates the WRF/CMAQ with EPIC through the current release of the Spatial Allocator (SA v4.2) Raster Tools system. The interface contains 13 sub-interface tools which guide users through the EPIC simulations for CMAQ. The FEST-C system can be used in assessing not only the impacts of agricultural fertilization and management practices on the air quality (NH3) and climate (N2O), but also the impacts of meteorology/climate and air quality (N deposition) on crop yield, soil erosion and overall nitrogen, carbon and phosphorus biogeochemical status of the agricultural ecosystem.
Java-based FEST-C interface with 13 sub-interface tools to:
- Build the input database of 21 crops for EPIC model simulations for a given CMAQ domain
- Simulate daily fertilizer application information based entirely on simulated plant demand in response to local soil and weather conditions using EPIC,
- Extract EPIC daily output for CMAQ bi-directional NH3 modeling, and
- Visualize the simulation results spatially over the modeling domin.
EPIC Modeling system including:
- EPIC model version 0509 from Texas A&M University (TAMU), modified by EPA to meet CMAQ input requirements,
- Utility programs to build EPIC input data sets for CMAQ domain grid cells,
- Common data sets (e.g. weather station climate statistic files and built soil data files) included in the EPIC modeling,
- Scenarios which contain a test case and to store users' application scenarios, and
- Documentation of the EPIC Modeling System for CMAQ 12km Grids in the FEST-C.
- Follow the documentation for installation
- FEST-C works for domains at different resolutions and in any of the four WRF projection coordinate systems - longitude/latitude, Lambert Conformal Conic, Universal Polar Stereographic, and Mercator
UPDATES in Version 1.2
- Enhanced FEST-C interface options for spinup and app simulations
- Modified daily and annual output to include wind erosion and phosphorus variables
- Added more utility tools to process EPIC output data
- Elevation bug fix
Latest Version: FEST-C version 1.2
Hands-on FEST-C training will become available to the community in the near future.

History of FEST-C
- FEST-C V1.2 (05/31/2016) - Updated release
- FEST-C V1.2 (02/09/2016) - Updated release
- FEST-C V1.2 (09/30/2015) - Updated release
- FEST-C V1.1 (05/30/2014) - Updated release
- FEST-C V1.0 (10/25/2013) - First release
The development of the system has been funded by the EPA. The creation of the FEST-C interface and EPIC application was driven by the 2012 release of the bi-directional NH3 option for CMAQ. While there are other EPIC model user interfaces, FEST-C has been specifically designed to require minimal user inputs and to produce bi-directional CMAQ-ready output files for any CMAQ domain and grid cell resolution for which MCIP data is available.
