Estimando la frecuencia e intensidad las olas de calor: Un caso de estudio en Chicago
Modelado numérico mostró los impactos extendidos de la ola de calor del 2012 en Chicago, clarificando los impactos de la ola de calor y la isla de calor urbana en la temperatura de la ciudad.
Trees Wearing Accelerometers Help Track Snowstorms
This device allows scientists to measure how much snow is trapped in canopies and predict changes to snowpack—a critical factor in annual water availability.
Hidden Upwelling Systems May Be Overlooked Branches of Ocean Circulation
New research suggests that overlooked upwelling systems in western boundary currents play a role in transporting nutrients, carbon, and heat in the global ocean.
Lightning Had Difficulty Forming in Early Earth’s Atmosphere
Lightning could have sparked the beginnings of life, but the primordial atmosphere might have made it more difficult for lightning to initiate.
Testing a Machine Learning Approach to Geophysical Inversion
Variational autoencoders can be leveraged to provide an effective method of inversion that is both accurate and computationally efficient.
Tree Rings Reveal a Puzzling Trend in Monsoon Intensity
Tree rings confirm that in northern Australia, the past 40 years have experienced more rain than any similar length of time in the past 600 years.
Fresh Approaches to Processing GRACE Data
Two studies showcase new methods for analyzing GRACE data that better match the land surface, producing clearer estimates of mass variations.
Satellites’ Lasers Reveal Changes in Earth’s Water Movement
The laser-based instruments aboard the GRACE-FO satellites may be extended to other geophysical applications to collect data on other submonthly mass changes in Earth’s system.
