A numerical framework for operational coupled fire-atmosphere-fuel moisture-smoke forecasting
October 25, 2018 11:00 am
CIRA Directors Conference Room
Presented by: CIRA
Hosted by: Jan Mandel, University of Colorado Denver (presenting) Adam Kochanski, University of Utah Sher Schranz, CIRA Martin Vejmelka, AVAST
We present an integrated wildland fire model WRF-SFIRE, based on combining a high resolution, multi-scale weather forecasting model WRF, with a semi-empirical fire spread model, a prognostic dead fuel moisture model, and smoke dispersion. Fire-released heat and moisture impact local meteorology. The fuel moisture model is driven by the atmospheric component of the system in… Read more »
How much will Earth warm? Looking for clues in Earth’s historical energy budget.

CIRA Directors Conference Room
Presented by: Mark Richardson
Hosted by:
JPL/Caltech/UCLA JIFRESSE
Abstract: The amount of global warming we expect is controversial in the media. A common metric for this is Equilibrium Climate Sensitivity (ECS), which is the eventual warming following doubled atmospheric CO2. Recently published estimates include “maybe things won’t be that bad” (1.7 °C) and “we could probably destroy most of civilisation” (5.3 °C), but… Read more »
Viewing the Earth’s Global Environment from Space: from Scientific Knowledge to Societal Benefits
October 11, 2018 3:00 pm
ATS room 101
Presented by: Jack A. Kaye
Hosted by: A. R. Ravishankara
Associate Director for Research, Earth Science Division NASA HQ – Science Mission Directorate
The vantage point of space provides a unique opportunity to see all the elements of the global Earth system – atmosphere, ocean, land surface, ice, biosphere – and how they interact with each other. The ability to characterize both natural processes and those caused by humans, as well as the ability to study processes on… Read more »
Wildfire-Driven Thunderstorms Cause a Volcano-Like Stratospheric Injection of Smoke
October 23, 2018 11:00 am
CIRA Directors Conference Room
Presented by: David A. Peterson
Hosted by: James R. Campbell, Edward J. Hyer, Michael D. Fromm, George P. Kablick, Joshua H. Cossuth, Matthew T. DeLand
Naval Research Laboratory
Intense heating by wildfires can generate a deep, smoke-infused thunderstorm, known as pyrocumulonimbus (pyroCb). This extreme weather phenomenon can release a large quantity of smoke particles into the upper troposphere and lower stratosphere. The meteorology driving pyroCb occurrence, combined with increasingly active fire seasons, indicates that pyroCb are a significant and endemic summertime feature in… Read more »
