  • Brief Bio

    Dr. Thomas Clune is a senior computational scientist at NASA GSFC and leads the Software Infrastructure Team within the Global Modeling and Assimilation Office. Dr. Clune has ongoing software collaborations for the development of numerous models across several disciplines. 


    Dr. Clune serves as the NASA representative on the Fortran language committee, where he currently leads the subgroup focused on introducing generic programming features into Fortran.


    Dr. Clune is a strong advocate for open source software and best practices for development of scientific software, and in particular for test driven development. He is the lead developer of pFUnit, an open source unit testing framework for parallel Fortran Software. This highly-extensible framework has successfully been used in testing and development of several software packages within NASA, and is also being used at several prestigious institutions including \ac{ECMWF} and \ac{NCAR}. Other open source packages developed by Dr. Clune include gFTL, a templating library for Fortran, pFlogger, a logging utility for Fortran, and yaFyaml a YAML parser with customized Fortran interfaces..


    Research Interests

    Development of Scientific Software

    Current Projects

    A Framework for Global Cloud Resolving OSSEs.

    Dr. Clune serves on this project which is funded by NASA's Advanced Information Systems Technology program. The project aims too reduce the cost and complexity of simulating instrument observations within the context of a high-resolution nature run. The project will achieve this by developing a pluggable framework that allows researchers to separately provide their own instrument simulator, observation geometry, and output collections.
