New Lidar Comparisons of Temperatures Near the Mesopause
For the first time, simultaneous measurements of upper atmosphere temperatures over altitudes 80 to 110 kilometers have been made by two complementary lidar techniques.
How Do We Accomplish System Science in Space?
Exploring Systems-Science Techniques for the Earth’s Magnetosphere-Ionosphere-Thermosphere; Los Alamos, New Mexico, 24–26 July 2018
Observing Winter Mixing and Spring Bloom in the Mediterranean
A new special issue of JGR: Oceans and JGR: Atmospheres presents new insights into the dynamics of dense water formation in the western Mediterranean Sea and its biogeochemical consequences.
Seeing Waves: GNSS Tracking of Waves in the Upper Atmosphere
Dense GNSS networks enable scientists to track large-scale waves traveling through the upper atmosphere, away from sources in the auroral zone and the day/night terminator.
New Characterization of the Mesospheric Polar Vortices
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.
UCAR to Keep Managing National Center for Atmospheric Research
The head of the University Corporation for Atmospheric Research says he is excited about “taking our science to the next level.”
Wind Speed Governs Turbulence in Atmospheric Inversions
Measurements made during a field campaign in Idaho indicate that the speed of winds 2 meters above Earth’s surface determines the type of turbulence present in nighttime inversions.
How Did Life Learn to Breathe?
Scientists unravel the conditions under which life evolved to breathe oxygen—and the findings have some stellar implications.
Dramatic Stratospheric Warmings Carved a Hole in the Ionosphere
A new study of sudden temperature spikes in Earth’s stratosphere could improve space weather forecasting.
