The public is invited to a free talk called ‘Mapping the Blue Marble: Using Space-Based Observations for Improved Global Water Security and Sustainability,’ with Dr. John Bolten in the Pickford Theater, third floor, Madison Building, Library of Congress, Washington, D.C., on May 15 from 11:30 a.m. to 12:30 p.m. EDT.

This visualization shows the correlation and lag time of surface soil moisture following precipitation events over Australia, India, and the United States. It uses the new NASA-USDA-FAS Soil Moisture product, a joint effort of NASA and the USDA Foreign Agricultural Service, and the global Integrated Multi-satellite Retrievals for GPM (IMERG) precipitation dataset, which provides rainfall rates for the entire world every thirty minutes. This animation shows the 30-minute rainfall product, while the soil moisture data is a three-day moving average. Credits: NASA’s Scientific Visualization Studio

Bolten is a speaker in the 2018 NASA Goddard Lectures Series at the Library of Congress. Bolten is the associate program manager of water resources for the NASA Applied Sciences Program at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.  

The combined stresses of overpopulation, water pollution and poor water-management practices require new approaches to better assess and manage global water security and sustainability. Bolten will review the technological advances in satellite-based remote sensing and numerical modeling of reservoir volume, vegetation health, groundwater movement, soil moisture and other factors that drive these new approaches and discuss how the data are being applied to address these global issues.
