Upcoming Machine learning/RHESSys output presentation

This Master of Environmental Data Science (MEDS) Capstone Project Presentation features a machine learning algorithm designed to interpret RHESSys output and extract meaningful insights into the possible impacts of climate change on forest health, and visualize findings in an interactive manner that is accessible to forest managers, students, and the general public.

New publication explores when fire regimes shift from flammability- to fuel-limited

In this new publication, RHESSys-WMFire is used to address the overarching question: How does vegetation modulate the effects of climate change on fire regimes in a semiarid watershed? More specifically – what are the relative and opposing roles of key exogenous drivers (climate change/CO2) and key endogenous drivers (fuel load/fuel aridity) in driving fire regimes.

(2022) Projecting future fire regimes in a semiarid watershed of the inland northwestern United States: Interactions among climate change, vegetation productivity, and fuel dynamics, Earth’s Future 10(3), e2021EF002518. doi: 10.1029/2021EF002518

Lab collaborator Khorchani PhD defense

Congratulations to lab friend and collaborator Makki Khorchani (Instituto Pirenaico de Ecología (IPE-CSIC)) on his PhD defense last Friday of his dissertation “Effects of post-land abandonment management strategies on water resources, vegetation dynamics, and soil properties and redistribution in the central Spanish Pyrenees”. He used the RHESSys model to simulate the different vegetation and climate scenarios explored in his research.

Naomi interviewed on ‘Who’s your Data?’ podcast

Naomi Tague was recently interviewed by Gilad Barash on his ‘Who’s your Data?‘ podcast about her research predicting and forecasting forest fire frequency and severity, data used in models, machine learning, and her work in developing ways to visualize the results to help officials and the public understand the processes and impacts of fire on our landscapes.

Tague presentation at AI4ESP workshop

Last week Naomi Tague presented “How Big Data and Machine Learning Can Complement Process-based Ecohydrology Models” at the Artificial Intelligence for Earth System Predictability (AI4ESP) workshop.

The AI4ESP initiative is a collaboration between DOE management and laboratories to understand the paradigm shift required to enable AI across the MODEX enterprise, in part by determining the most impactful applications along the observation-modeling continuum.

156 White Papers were solicited for the development and application of AI methods in areas relevant to EESSD research, with an emphasis on quantifying and improving Earth system predictability, particularly related to the integrative water cycle and extreme events. Submitted white papers were used to inform the design of three sequential workshops (conducted in 2021-2022) focused on answering the question:

How can DOE directly leverage artificial intelligence (AI) to engineer a substantial (paradigm-changing) improvement in Earth System Predictability?
