Satellite Data Reveal Uptick in Cover Cropping on Farms

Katherine Kornei, Science Writer by Katherine Kornei 20 December 202220 December 2022

Over the course of a decade, farmers growing corn and soybeans in the U.S. Midwest increased their adoption of cover cropping—a tenet of so-called conservation agriculture—by fourfold.

Vegetation Carries the Signature of Recent Precipitation

by Valeriy Ivanov 3 October 202228 September 2022

Vegetation response to precipitation is important for near-term weather predictability, and researchers show that such a response can occur within a few days and last up to two months.

A Dilemma About Radiative Climate Feedback in Recent Decades

by Minghua Zhang 30 September 202228 September 2022

Given the unambiguous climate warming in recent decades, is it possible to infer radiative climate feedback from modern satellite measurements of the energy budget of the Earth?

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.

Monitoring the Health of Our Planet using Earth Observations

by Argyro Kavvada 8 September 202230 September 2022

A new book explores how Earth science knowledge addresses critical global challenges including sustainable development, disaster risk reduction, and climate change.

A small coastal shipping town in Japan is devastated by an earthquake. In this photo taken from a plane, the wreckage of hundreds of buildings can be seen, and only a handful remain standing. In the center of the image, a small yacht is perched on top of one of the only remaining buildings. The town is surrounded by mountains and forests. One of the plane’s wheels is visible in the lower left corner of the image.

Months of Gravity Changes Preceded the Tōhoku Earthquake

Sarah Derouin, Science Writer by Sarah Derouin 1 September 202225 October 2022

Using GRACE satellite data, researchers discovered anomalous gravimetric signals that occurred before a seismic event that started deep within Earth.
