Summary
👤
Senior🎓
Top SchoolBarron Henderson is a Physical Scientist with 17 years of experience applying atmospheric science, statistical methods, and software engineering to air quality modeling and satellite data analysis. Based at the EPA in Cary, NC, he blends distributed computing, cloud development, Bayesian inference, and machine learning to turn complex environmental data into actionable policy insights. He has coauthored 72 peer-reviewed papers, earned multiple EPA national honors including a 2024 Scientific and Technological Achievement Award, and is an active open-source contributor to high-profile projects like THREDDS and CMAQ. His work spans hands-on code contributions that improve model I/O, metadata, and projections to leadership and public-facing communication as a sought-after speaker. Notably, he bridges academia and government practice—shaping models used in regulation while maintaining dozens of primary developer repositories that modernize atmospheric science tooling.

USEPA/CMAQ
Nov 2017 - Aug 2022
Code for U.S. EPA’s Community Multiscale Air Quality Model (CMAQ) which helps in conducting air quality model simulations
Role in this project:
Back-end Developer
Back-end DeveloperContributions:26 commits, 2 comments, 1 issue in 4 years 8 months
Contributions summary:Barron's commits primarily focus on extending and modifying the `pwrvec.f` module for vertical column extraction within the CMAQ model. These changes involve adding new environmental variables for specifying extraction coordinates and integrating this functionality into the model's I/O operations. Further commits refine this implementation through bug fixes, clarity improvements, and modularization, ensuring data is correctly written and processed within the CMAQ framework. This work is critical to the model's data handling and analysis capabilities.

Jun 2013 - Jan 2018
THREDDS Data Server v4.6
Role in this project:Back-end Developer
Back-end DeveloperContributions:10 commits, 4 PRs, 3 comments in 4 years 7 months
Contributions summary:Barron primarily focused on enhancing the UAMIV Service Provider within the THREDDS Data Server. Their contributions involved updating the codebase to incorporate new metadata from CAMx version 6, improving data type correctness, and adding unit awareness to the data variables. Additionally, the user addressed and corrected the handling of empty lines in the code. Further work involved improving WRF Projections and fixing coordinate variable definitions.
