Methane Source Finder

The Methane Source Finder (MSF) project will implement a science data system (SDS) capable of streamlined processing and visualization of airborne methane remote sensing data products. NASA imaging spectrometers AVIRIS-NG and HyTES are effective at surveying large areas and generating high-resolution maps (1-3 meters per pixel) of atmospheric methane enhancements in the aircraft subcolumns. Surveys using both sensors in 2013-2015 have successfully detected hundreds of methane point sources during surveys in California, New Mexico, and Colorado. There is strong interest in methane point source detection and attribution by stakeholders in government agencies and private sector. These data offer great value to these stakeholders if these methane data products are generated with low-latency and accessible by non-expert users. The
current manual analysis workflow is very time-consuming, requires specialized expertise and could greatly benefit from increased automation and integration. The MSF SDS will be capable of rapid generation of level 3 (L3) products via the MSF data pipeline subsystem. These L3 products will then be ingested by a analysis and visualization subsystem. The MSF system will leverage and integrate several existing NASA data system tools. The system will create a L4 data output file that helps users characterize and confirm methane point sources.

We are collaborating on the MSF project with two key State of California stakeholders: (a) the California Air Resources Board, and (b) the California Energy Commission. Our second project objective is to work with these collaborators to demonstrate the use of the MSF Science Data System under operational conditions during a planned airborne methane survey over the state of California in 2016.
