Volcanic Ash: Detection & Height

 caption follows:
Ash Detection product (left), as indicated by white contour (i.e., all pixels within contour deemed to contain volcanic ash) overlaid on false color Meteosat-9/SEVIRI image as generated by the GOES-R Volcanic Ash algorithm. The associated ash loading retrievals are also shown (right).

The Volcanic Ash product algorithm utilizes five GOES-R ABI infrared channels to automatically determine the height and mass loading properties of any pixel found to contain volcanic ash. Forecasters will be able to use the Volcanic Ash product to identify areas where volcanic ash is present and potentially hazardous, and ultimately, issue more accurate aviation, air quality, and public health warnings. It is also expected that the Volcanic Ash product will be useful for initializing dispersion models and volcanic ash trajectory prediction models. The more accurate mass loading detection may also aid in forecasting short-term climate changes due to volcanic eruptions.
