NWS Volcanic Ash Training

Carl Weiss

U.S. AMDAR Representative

  • As a result of the Eyjafjallajökulleruption and its disruption to the aviation industry across Europe, the need for NWS operational meteorologists to better understand the environmental features and impacts of a volcanic eruption became apparent.
  • Operational forecasters must:
    • understand volcanic ash sources and physical processes,
    • predict the trajectory of volcanic ash using forecast products,
    • be aware of the impacts of volcanic ash on aviation, public health, climate, water quality and agriculture,
    • communicate effectively with the public.
  • An NWS directive recently has been implemented that addresses appropriate forecaster response to eruptions.
background continued
Background (Continued)
  • Target audience for thistrainingis current operational NWS and private sector meteorologists.
  • Secondary audiences for this course might vary widely, including:
    • federal agencies,
    • state and local government agencies,
    • non-governmental organizations,
    • universities,
    • international agencies.
  • Although some online sources and existing modules refer to volcanic ash and its impacts, this course is the first comprehensive training to treat this subject.
course development
Course Development
  • A development team was assembled representing NWS, COMET

and the climate community.

  • Team core members were:
    • Warren Rodie and Dr. Elizabeth Page - COMET Project Leads
    • Dr. Alan Bol - COMET Geologist
    • Tsvetomir Ross-Lazarov - COMET Instructional Designer
    • Paul Witsaman - NWS Project Lead, Regional Aviation Meteorologist, NWS SRH
    • Ken Venske - Meteorologist in Charge, CWSU Oakland, CA
    • Leslie Wanek – Impact Decision Support Services Manager, NWS WRH
    • Rich Mamrosh - Aviation Focal Point, WFO Green Bay, WI
    • Jeff Osiensky- Regional Aviation Meteorologist, NWS ARH
    • Scott Birch - Regional Aviation Meteorologist, NWS WRH
    • Dr. Alan Robock - Professor (Climate Change), Rutgers University
course description
Course Description
  • Volcanic ash training focuses on providing forecasters:
    • an understanding of the source and characteristics of volcanic eruptions,
    • techniques for volcanic ash detection,
    • techniques for forecasting plume movement,
    • an understanding of impacts to aviation, climate, society, and water resources.
  • Course is comprised of 4 modules:
    • Introduction
    • Volcanism
    • Impacts
    • Observation Tools and Dispersion Models
course description continued
Course Description (Continued)
  • Module format:
    • fully interactive, online module with text, animations, images and exercises,
    • embedded links allow students to selectively view topics in the module,
    • a print version is available so students can print sections related to their immediate needs,
    • each module contains references and a bibliography.
    • questions embedded in the training will evaluate student’s immediate retention of knowledge and will prepare them for the quiz at the end of each module.
module 1 introduction
Module 1: Introduction
  • Introduction
    • EyjafjallajökullVolcano (2010)
