Impact/Purpose:
The National Exposure Research Laboratory (NERL) Computational Exposure Division (CED) develops and evaluates data, decision-support tools, and models to be applied to media-specific or receptor-specific problem areas. CED uses modeling-based approaches to characterize exposures, evaluate fate and transport, and support environmental diagnostics/forensics with input from multiple data sources. It also develops media- and receptor-specific models, process models, and decision support tools for use both within and outside of EPA.
Description:
The Atmospheric Model Evaluation Tool (AMET) is a suite of software designed to facilitate the analysis and evaluation of meteorological and air quality models. AMET matches the model output for particular locations to the corresponding observed values from one or more networks of monitors. These pairings of values (model and observation) are then used to statistically and graphically analyze the model's performance. A new version of AMET (version 1.3) was released in July 2017. A number of updates have been made in version 1.3 from the previous version (1.2). One major update in AMETv1.3 is the replacement of the perl code with R code, which simplifies the installation of AMET as it no longer requires users to install perl and the previously required perl packages. The database setup and creation has also been simplified, with the number of required input files reduced. The MySQL credential management has been made more robust to handle password control, while the speed of the MySQL data loading has also been improved. On the AQ side of AMET, support for the AMON and FLUXNET networks has been added to AMETv1.3, along with additional analysis scripts and query options. A batch analysis script has also been added which creates pre-defined plots using a single script, eliminating the need for a user to modify and run the individual analysis scripts. This seminar will present a brief overview of AMET and the updates in AMETv1.3.
