Dr Webley joined the Geophysical Institute in February 2009 after arriving in Alaska in Fall 2005 and spending several years as a Post Doctoral Fellow at the Arctic Region Supercomputing Center. His research interests lie in volcanic ash cloud and plume detection through thermal and visible remote sensing as well as volcanic ash cloud modeling using Lagrangian transport and dispersion models. Given his background in thermal and radar based remote sensing, he also has an interest in real-time detection of ground based volcanic activity through remote sensing datasets and how to sue these for hazard assessment and risk mitigation. Through his research projects and collaborations, Dr Webley works closely on with both groups across UAF as well as further afield in the USGS, NASA, NSF, State University of New York - Buffalo, Michigan Technology University.
He is also the main teacher for the Remote Sensing of Volcanic Eruptions class, GOES-676 (http://www.puff.images.alaska.edu/classes/) in the UAF Department of Geology and Geophysics (http://www.uaf.edu/geology/). In addition to his research interests, Dr Webley is heavily involved in Education and Outreach, serving as a member of the GI Education group and being involved in several research projects, including how to provide learning tools and skills on the use of GIS and Google Earth in the classrooms of Alaska (http://mapteach.org)
He is part of the UAF-Alaska Volcano Observatory (AVO) Remote Sensing group involved in operational use of remote sensing data for the volcanoes in Alaska. As part of this group, Dr Webley is responsible for the Puff model predictions of the volcanic ash dispersion during operationally monitoring. In addition, He is one of two scientists who take the responsibilities for the AVO Duty Remote sensing scientist. This is an on-call duty, 24 hrs a day. He is also responsible for the development and maintenance of the automated Puff model ash dispersion predictions for elevated alert volcanoes for the NOPAC and beyond. This is displayed via website (http://puff.images.alaska.edu).
Within the University of Alaska Fairbanks, Dr Webley is the UAF Faculty Senate Research Advisory Committee co-chair as well yearly he provides an instructional two-week module for the Alaska Summer Research Academy (http://www.uaf.edu/asra/asra-2012/Denali%20Rocks/). Outside Alaska, Dr Webley is the America's and Caribbean chair for the World Organization of Volcano Observatories (http://wovo.org) and on the Steering Committee of the Global Volcano model project (http://www.globalvolcanomodel.org/).
