A NASA study has found a link between climate change effects on the productivity of grasslands and the growing number of bison in Yellowstone National Park. The data, which came from two NASA Earth science satellites, shows daily vegetation growth for the past 20 years and can be used to help forecast the movements of bison, aiding conservation eff
Dr. Kurt Thome, Terra
Project Scientist was featured in a Data Chat – short, informal discussions
with scientists, managers, and members of NASA’s diverse data-user community.
Thome provides personal insights into how Terra data are being used around
the world, along with a glimpse into how these data, products, and services may
be used in the future. Read more https://earthdata.nasa.gov/learn/data-chat/data-chat-dr-kurt-thome.
What do you get when you have an Earth observing satellite mission that collects science-quality data from five instruments for more than 20 years? You get groundbreaking science, more than 20,000 peer-reviewed publications, and a critical understanding of how our planet works. In other words, you get NASA’s Terra mission. Read about how the instruments aboard NASA’s flagship Earth observing mission are compiling a monumental climate data record and what this means for you in “Terra: Five Instruments—One Monumental Data Record,” now available on NASA’s Earthdata website.
Terra’s MODIS and MISR instruments were featured in an article in AGU’s eos.org, titled, A Global Perspective on Wildfires. The article, written by Ralph Kahn, highlights how twenty years of satellite data are used in wildfire management.
“Remote sensing instruments are relatively blunt objects for characterizing wildfires and their impacts, compared with traditional in situ monitoring. However, they offer the advantage of providing frequent, broad coverage at minimal incremental cost and at no risk to observers. Over the past 20 years, the research community has developed tools and techniques to capture key aspects of fire behavior and impacts, with data from spaceborne instruments such as the Moderate Resolution Imaging Spectroradiometers (MODIS) aboard NASA’s Terra and Aqua satellites and the Multiangle Imaging Spectroradiometer (MISR) aboard Terra. This article reviews selected contributions that satellite instruments are making to advance our understanding and monitoring of, as well as our responses to, wildfires globally.”
Terra’s contributions to how we view our entire planet, affectionately called the Blue Marble, were recognized as part of the Blue Marble story.
Additionally, NASA’s Earth Observatory, known for being a major source to the public of images, stories, and discoveries about the environment, Earth systems, and climate that emerge from NASA research, was featured for their twenty years of operation. NASA’s Earth Observatory website was born out of Terra’s education and outreach initiative during launch.
