We provide a test case to help new CAMx users get started and to perform performance benchmarking. The test case is based on the US EPA’s 2016 Modeling Platform that includes a large North American domain (36-km mesh) and a nested domain covering the Eastern U.S. (12-km mesh). The test case includes inputs and outputs for 2 days of simulation over June 10-11, 2016. Gas-phase chemistry is treated using the CB6r5 mechanism and PM is treated with the CF3 scheme (RADM-AQ for aqueous chemistry, EQSAM for inorganic chemistry, SOAP3 for organic chemistry).
The model inputs are divided into three tar files (met, emissions and other). Another tar file provides the resulting model outputs for comparison. The “version-specific” file contains chemistry parameter input files and test case job scripts specific to CAMx v7.40.
To get data and test files for CAMx versions prior to v7.40, please send a request to CAMx.
