David is a Scientific Associate working as an applications programmer for the DOE’s Atmospheric Radiation Measurement (ARM) program. He has developed programs that create atmospheric state and thermodynamic profiles using data from multiple ARM instruments. These Value-Added Products (VAPs) are among the most used products from the ARM Data Archive. The VAPs developed by David include high resolution profiles combining radiosonde and model data (Mergesonde), high resolution radiosonde profiles (Interpolatedsonde), humidity corrected radiosonde profiles (Sondeadjust), and cloud boundaries and hydrometeor detection (WACR-ARSCL). Understanding the structure of Atmospheric Science using the tools of domain analysis – bibliometrics, ontologies, and metadata characteristics – is part of his doctoral research agenda.
