Drought Severity Evaluation Tool: An Earth Observation collaboration with the Navajo Nation

Nikki Tulley, Research Scientist, Capacity Building Program, BAERI/NASA Ames Research Center

Nikki Tulley is a member of the Navajo Nation, an Indigenous Nation located in the United States southwest. She works with the NASA Capacity Building Program and is part of BAERI/NASA Ames Research Center. As an Indigenous Scientist, she recognizes that opportunity to braid Indigenous science and western science together to use Earth Observation satellite imagery to tell a story of the changes being monitored from space and those observed from the landscapes. Nikki's passion is empowering communities through data access and capacity building. She believes that community involvement in research can significantly aid in seeking solutions for resilient and sustainable communities.

An Introduction to The National Oceanic and Atmospheric Administration’s (NOAA's) National Integrated Drought Information System (NIDIS)

Amanda Sheffield, Senior Associate Scientist, University of Colorado Boulder Cooperative Institute for Research in Environmental Sciences (CIRES) affiliated with National Oceanic and Atmospheric Administration's (NOAA) National Integrated Drought Information System (NIDIS)

Amanda is a Senior Associate Scientist at the University of Colorado Boulder Cooperative Institute for Research in Environmental Sciences (CIRES)affiliated with National Oceanic and Atmospheric Administration's (NOAA's) National Integrated Drought Information System (NIDIS). She is a Regional Drought Information Coordinator for the California-Nevada Drought Early Warning System (DEWS), working with partners across all levels of government, academic institutions, and the private sector to improve capacity to monitor, forecast, plan for, and cope with the impacts of drought. She also supports NIDIS on efforts on subseasonal to seasonal forecasting and snow drought as well as drought in Hawaii and the U.S. Affiliated Pacific Islands. Amanda holds degrees in Atmospheric Science from Colorado State University (Ph.D., M.S.) and Purdue University (B.S.).

Translating Water Extent into Water Availability Scores - a Methodology to Diagnose Surface Water Availability Problems

Renato Frasson, NASA Western Water Applications Office / Jet Propulsion Laboratory

Renato is a scientist in the Water and Ecosystems group at NASA JPL with nearly a decade of experience in using remote-sensing images to track the evolution of rivers and lakes. At JPL, he supports the Surface Water and Ocean Topography (SWOT) mission and the Observational Products for End-Users from Remote Sensing Analysis (OPERA) project. Renato’s areas of research include measuring and estimating river properties and hydraulic characteristics where in situ measurements are unavailable, uncertainty analysis and quantification, and harmonizing data collected by different instruments. Within WWAO, Renato strives to connect stakeholders and potential data users with the right data products, and to remove hurdles that impede the use of remote-sensing information to support decision making. He holds a Ph.D. degree from the University of Iowa and spent eight years at Ohio State University.

Using NASA Satellite Data with an AI-Based River Hydrology Model to Improve Operational Water Supply Forecasts

Dr. Sean Fleming, U.S. Department of Agriculture Natural Resources Conservation Service, now Oregon State University

Sean is a geophysicist by training and an applied water, climate, and environmental scientist by profession. He has over two decades of experience in the private, public, and non-profit sectors in several countries, spanning field, technical, managerial, business, and communications roles. Career highlights so far include developing some of the first AI-driven river forecast systems in operational use at governmental service-delivery organizations, discoveries about how glaciers affect the way rivers respond to climate variation and change, writing a general-audience book for Princeton University Press and op-eds for Scientific American and Wired, being invited to talk at the Smithsonian, and volunteering in Mexico, Romania, Mauritania, and wartime Ukraine.

Addressing Critical Science and Data Gaps to Improve Water Management in New Mexico

Max Gersh, New Mexico Office of the State Engineer

Max Gersh is a Senior Hydrologist with the New Mexico Office of the State Engineer – Water Resource Allocation Program. Max obtained a Bachelor of Science in Hydrology and Water Resources from the University of Arizona and a Master of Science in Environmental Science and Management from Portland State University where he focused on forest fire effects on snow albedo and snowmelt timing in the Western US. His work experience includes the use of gravity surveys for aquifer monitoring, remote sensing and GIS-based hydrology work, satellite imagery analysis, water rights allocation, groundwater modeling, and surface water/groundwater interactions.
