New satellite images of "significant environmental events" are posted frequently at the National Oceanic and Atmospheric Administration (NOAA)'s Operational Significant Event Imagery (OSEI) Website. Remotely-sensed data include "high-resolution, detailed imagery" of dust storms, fires, floods, icebergs, oceanic events, severe weather, snow cover, storm systems, tropical cyclones, volcanoes, and other current events. Users may search the site for the most recent images by date or by topic. A Daily Report section provides brief descriptions of the latest images.
