Soufrière St. Vincent April 13 2021 Eruption

The NOAA/CIMSS VOLCAT system is experimentally run at Space Science and Engineering Center (SSEC) at the University of Wisconsin using near real-time NOAA satellite data in support of volcano monitoring and forecasting. One data source available to VOLCAT is the GOES-16 Advanced Baseline Imager (ABI) data. GOES-16 ABI is providing frequent observations of the on-going […]

New VOLCAT Event Dashboard Configuration Options

The VOLCAT Event Dashboard (https://volcano.ssec.wisc.edu/event-dashboard/) was developed to facilitate more timely uptake of VOLCAT alerts. Feedback from end-users was very favorable and one common theme for future improvement was for more granular volcano filters that gives users more control over which volcanoes will appear on the user’s instance of the Event Dashboard, should an event […]

JPSS Volcanic Hazards Initiative: VOLCAT SO2 Properties

This post is a companion to the previous post on VOLCAT SO2 Alerts. Please see that post for background on the CrIS instrument and definitions of the acronyms used here. In particular, it deals with the SO2 cloud properties derived in VOLCAT by the CrIS SO2 algorithm. The CrIS algorithm estimates the height and column […]

JPSS Volcanic Hazards Initiative: VOLCAT SO2 Alerts

As described in a previous blog post, the Joint Polar Satellite System (JPSS) Volcanic Hazards Initiative seeks to develop volcanic cloud products from the JPSS series satellites (Suomi-NPP, NOAA-20) addressing current and future needs of the International Civil Aviation Organization (ICAO) International Airways Volcano Watch (IAVW). A major component of this work has been the […]

JPSS Volcanic Hazards Initiative: Introduction to the VOLCAT SO2 Product Suite

The NOAA Joint Polar Satellite System (JPSS) Volcanic Hazards Initiative is aimed at developing products that address current and future needs of the International Civil Aviation Organization (ICAO) International Airways Volcano Watch (IAVW), including products that support volcano observatory operations. The ICAO/IAVW sets the standards for volcanic ash advisories issued in support of aviation (NOAA […]

2018 WMO Volcanic Ash Intercomparison — validation for Etna (04 Dec. 2015)

For the 2018 WMO Volcanic Ash Intercomparison, two experts at the University of Wisconsin independently identified volcanic clouds in multispectral infrared satellite imagery. Seventeen times were selected for validation during this eruptive event. The images below show multispectral imagery with yellow and green polygons overlaid, representing the experts’ analysis of where ash is present. Please […]
