OSPO Volcanic Ash Products:

ICAO -- Volcanic Ash Advisories Satellite Imagery
Sample VAA Image International Civil Aviation Organization (ICAO) Products include Volcanic Ash Advisories (VAA) and associated Volcanic Ash Graphic (VAG) - VAA are issued every 6 hours or sooner for ash active volcanoes with VAG when ash is detected. Volcano Satellite Graphic Imagery from the GOES-16/GOES-18/Himiwari satellites.

SO2 Imagery OMPS SO2
Sample ADT Graphic Latest Ozone Monitoring Instrument (OMI) imagery measuring SO2 - Includes 24-Hour Composite images and volcano specific images. Volcano Satellite Graphic The Ozone Mapping and Profiler Suite (OMPS) is a hyperspectral instrument which consists of three spectrometers designed to measure the concentration of ozone in the Earth's atmosphere.

Air Resources Laboratory (ARL) HYSPLIT Model NOAA Environmental Visualization Laboratory
Sample MTCSWA Graphic The ARL Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model is a complete system for computing simple air parcel trajectories to complex dispersion and deposition simulations. Sample OSEI Graphic High-resolution, detailed imagery of hazardous weather events as detected in remotely sensed data.

International Civil Aviation Organization (ICAO) Smithsonian Global Volcanism Program
ICAO Image The International Civil Aviation Organization was created in 1944 to promote the safe and orderly development of international civil aviation throughout the world. Smithsonian Graphic The Smithsonian's Global Volcanism Program seeks better understanding of all volcanoes through documenting their eruptions - small as well as large - during the past 10,000 years.
