Pangeo Showcase Presentation on Sep 20, 2023 by Erik Bolch: The Earth Mineral dust source InvesTigation (EMIT) imaging spectrometer aboard the international space station measures the spectrum of light ranging from the visible to infrared for each location in an image. This data can then be used to identify the distinct spectral signatures or fingerprints of materials present and applied across many scientific domains to map things like mineral types, vegetation species and health, snow grain size, water quality, dust, and greenhouse gases. NASA’s Land Processes Distributed Active Archive Center (LP DAAC) created and maintains the EMIT-Data-Resources repository 3, which contains Python workflows and Jupyter Notebooks developed and utilized within the Pangeo Framework. These resources leverage xarray and the HoloViz ecosystem to explore the data and create interactive visualizations. This showcase talk demonstrates creating an interactive map linked to a per-pixel spectral plot that can be used to explore the surface reflectance at different locations.
