“The Geography and Map Division is excited to support the newly launched “Library of Congress Geospatial Applications” Hub site! Hosted in ArcGIS Online, a web-based platform created by Esri, “the Hub” provides online users with a new way to explore the Library’s wide range of StoryMaps and web map applications in one site. Conveniently located at geo.loc.gov, the Hub is designed to provide an entry point to the Library’s geospatial products within ArcGIS Online, enabling thousands of digital map enthusiasts to discover our resources from where they are online. The Hub also provides map-based and faceted search capabilities to help you find specific applications or browse serendipitously. The Library of Congress Geospatial Applications Hub was spearheaded by the Geospatial Hosting Environment (GHE), a team within the Library’s Office of the Chief Information Officer that works to expand the use of Geographic Information Systems (GIS) technologies across the Library. The GHE worked in close partnership with the Geography and Map Division and other groups within the Library on this effort. The Hub complements the Geospatial Applications online collection, which showcases Library of Congress StoryMaps and web maps directly through loc.gov.”

The HRRR is a NOAA real-time 3-km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh.
