Dr. Ariel Stein gave an invited presentation on HYSPLIT activities related to transport and dispersion predictions related to air quality at the 2017 Meteorology And Climate – Modeling for Air Quality Conference organized by the University of California Davis and the California Air Resources Board. The conference took place from September 13 to 15, 2017 in Davis, California.


Kevin Birdwell and Erik Kabela from the Oak Ridge National Laboratory visited FRD on Thursday 14 September to discuss the HYRad dispersion modeling system that the division uses for radiological releases. They are looking for a new dispersion model for their own applications and are investigating HYRad as a potential candidate. Many of the modeling systems that have been used in DOE laboratories were largely supported by just one person and therefore are at risk of being orphaned when the developer retires or moves to another job. Systems based on HYSPLIT are attractive in the DOE laboratories both because HYSPLIT is open source and because the model is seen as having broader support.


The annual State of the Climate Report for 2016 has been published by the American Meteorological Society (AMS) as part of the August 2017 issue of the Bulletin of the American Meteorological Society (BAMS).  This 27th annual report is a check-up for the planet is based on contributions from more than 450 scientists representing over 60 countries around the world. It provides a detailed update on global climate indicators, notable weather events and other data collected from locations on land, water, ice, and in space. Some of the climate indicators include greenhouse gases; temperature; precipitation; sea level; sea ice extent; glacier mass; snow cover and tropical cyclones.  ATDD’s Howard Diamond served as the lead editor for the Tropics Chapter, and will repeat this role for the 2017 report that will be compiled during the first half of calendar year 2018. The Tropics Chapter covers global tropical cyclone activity in seven ocean basins across the globe, as well as documenting other tropical climate phenomena and their relationship to global climate effects such as the El Niño Southern Oscillation, Madden-Julian Oscillation, and Global Monsoon.  For more information on this, please contact Howard at 301-427-2475
