About

My primary responsibilities include managing Arctic data sets for Tiksi, Alert, and Eureka Arctic stations where I have become the primary NOAA-based data manager for these stations. Since taking on these stations, I have initiated the overhaul of both of their data-storage structures on the NOAA ftp-site while simultaneously establishing official data transfer processes. I also create “MindJet Maps” for data archiving support and organization for Tiksi, Alert, Eureka, and Summit stations. From these data sets I have created and developed data ingest software via MATLAB for reformatting, processing and displaying diagnostic and Arctic measurement data. Since my Arctic field visit to the Tiksi, Russia station in 2012, I have obtained many technical skills for supporting operations of Arctic instrumentation including installation, modification, troubleshooting, repair, calibration, and basic understanding of electronic systems at our Arctic station in Tiksi, Russia. I also provide technical support and maintenance for all of the Tiksi, Alert, and Eureka instrument suites and measurements by managing incoming data streams and instrument operations.

In-line with providing remote support for current and future Arctic instruments, I develop and evolve instrument “Datagrams” for technical, mechanical, and processing support that diagrammatically outline the flow of data from instrument. I am currently in the process of developing an automated system for future Datagrams as well as maintaining Datagrams for international collaborator’s instrument suites (Tiksi, Summit, Alert, and Eureka). I also develop and manage several procedures for data downloading (maintaining data stream flow of Arctic instrument suites), data archival (develop, implement, and maintain data stream organization structure), data retrieval (obtaining data-sets from international collaborations for ingesting purposes), and data submission to global/national archives. I also heavily participate in metadata assistance and implementation to the IASOA project, by hand-authoring metadata into the IASOA “Data-at-a-Glance” portal, and participating in the Black Carbon, Radiation, Flux, and Ozone individual Working Groups.

I am in pursuit of a graduate level degree in Arctic Physical Geography at the University of Colorado while continuing my full-time position at CIRES/NOAA. My thesis and corresponding area of research within the POP group highlight the variability of ground heat flux in the Arctic. This type of thermal energy flux is a part of the larger surface energy budget equation, of which I also participate in the study and improvement of radiative and turbulent flux measurements and instrumentation. My goal is to minimize inconsistencies and improve measurements to help close the net surface energy budget.
