The goal of the Airborne Data Visualizer (ADV) is to allow users to explore in-situ atmospheric gas measurements from multiple airborne missions through a single tool. The ADV consists of a web application, based in R Shiny, with menus for selecting individual flight dates and variables to view on a map or on a series of plots. Users can compare the geographic scope of measurements from multiple missions and determine which dataset meets their needs. Users can then follow the links on the page to download individual data files from the data pool, or they can view the dataset landing page to download larger amounts of data.
