OSPO Volcanic Ash Products:

ICAO -- Volcanic Ash Advisories		Satellite Imagery
	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.		Imagery from the GOES-16/GOES-18/Himiwari satellites.

SO2 Imagery		OMPS SO2
	Latest Ozone Monitoring Instrument (OMI) imagery measuring SO2 - Includes 24-Hour Composite images and volcano specific images.		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.

Volcanic Ash Advisory Centers (VAACs)		United States Geological Survey (USGS)
	In an effort to keep the aviation community informed of volcanic hazards, nine VAACs are tasked with monitoring the movement of volcanic ash within their assigned airspace. Washington \| Anchorage \| Buenos Aires Darwin \| London \| Montreal \| Tokyo Toulouse \| Wellington		The objectives of the USGS Volcano Hazards Program are to advance the scientific understanding of volcanic processes and to lessen the harmful impacts of volcanic activity. Yellowstone Observatory, California Observatory, Cascades Observatory

Air Resources Laboratory (ARL) HYSPLIT Model		NOAA Environmental Visualization Laboratory
	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.		High-resolution, detailed imagery of hazardous weather events as detected in remotely sensed data.

International Civil Aviation Organization (ICAO)		Smithsonian Global Volcanism Program
	The International Civil Aviation Organization was created in 1944 to promote the safe and orderly development of international civil aviation throughout the world.		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.
