Introducing the Advanced Baseline Imager on the GOES-R Series

Paul Menzel, Senior Scientist University of Wisconsin - Madison

Weekly Colloquium on Thursday, February 8, 2018 at 4 pm in Harvill 318

The Advanced Baseline Imager (ABI) launched November 2016 on the Geostationary Operational Environmental Satellite is introducing a wide range of qualitative and quantitative weather, oceanographic, climate, and environmental applications. ABI offers more spectral bands, higher spatial resolution, and faster imaging than the previous GOES imager. ABI spatial resolution is four times improved with 2 km for the infrared bands and 0.5 km for the 0.64-μm visible band. Flexible scanning scenarios offer a five fold increase in coverage rates.  Three times as many spectral bands (16 in all) offer more applications in land, sea, and atmospheric remote sensing. There are also improvements in radiometric performance, image navigation, and registration.  Overall ABI is 4x5x3=60 times more capable.  This talk will introduce the spectral bands and show some of their multispectral applications in a variety of weather phenomena.  In addition a data analysis toolkit (called HYDRA)will be demonstrated that provides interactive exploration and visualization of satellite sensor spectral measurements (displayed as brightness temperatures for infrared and reflectances for visible and near infrared) using spectra diagrams, transects, scatter plots, multi-band combinations, and RGB color enhancements.
