Field Campaign Explorer (FCX) Beta

A key component of NASA’s Earth Observing System is its field experiments, for intensive observation of particular phenomena such as hurricanes, or for ground validation of satellite observations.  These field experiments collect many datasets from a wide variety of satellite, airborne, and ground-based instruments, on different spatial and temporal scales, often in unique formats.  Such diverse environmental observations are important for physical process studies, disaster assessment and response, as well as for the validation of environmental satellite observations and atmospheric models which can improve forecasts.  However, the challenges inherent in working with such diverse datasets mean they are underused despite their value.

The Field Campaign eXplorer (FCX) addresses challenges inherent with utilizing these datasets to improve data management and discoverability to enable scientists to rapidly collect, visualize, and analyze these data. FCX was originally developed for the Hurricane and Severe Storm Sentinel (HS3) field campaign that investigated hurricane intensification. More recently, the Global Hydrology Resource Center DAAC has leveraged work from Visualization for Integrated Satellite, Airborne and Ground-based data Exploration (VISAGE) project. FCX has incorporated the lessons learned from VISAGE to transition FCX into a robust, cloud-native tool for exploring, visualizing, and analyzing diverse data in a common framework.
This recent architecture update to a cloud-native system has included two demonstration field campaigns that have been selected for the variety of datasets involved. These include data from the GOES-R Post Launch Test (PLT) and Olympic Mountains Experiment (OLYMPEx)  field campaigns. FCX incorporates science data collected from instruments onboard aircraft, ground sensors, and satellites. The instrument data are displayed within an interactive map viewer along flight tracks. This advanced tool reduces the effort involved in discovering data, is designed for event-based research, allows for seamless movement between data visualization, discovery and acquisition, and enhances the user experience by improving the usability of heterogeneous data. New proposed work aims to incorporate along-track subsetting, time and space matching between instruments, as well as cloud-native analysis tools.
FCX is currently in beta status and is under development including recently submitted proposals for follow-on work. The functionality to subset and download data granules, view flight reports, and view data from additional field campaigns. This will occur concurrently with the development of new analysis tools.
