Measuring Explosive Events on Earth from the Ionosphere
Natural and manmade explosive events occurring on or below the Earth’s surface can be measured remotely in different ways and different places from the ionosphere.
Unraveling the Origins of a Record-Setting Marine Heat Wave
The extreme heat wave in the southwestern Atlantic in 2017 was likely caused by upper atmosphere circulation patterns triggered by the Madden-Julian Oscillation tropical weather cycle.
The Thermosphere Responds to a Weaker Than Normal Solar Cycle
Infrared emissions from nitric oxide and carbon dioxide in Earth’s upper atmosphere, which are closely tied to incoming solar radiation, are drastically lower than in the previous solar cycle.
Aerosol Particle Size May Contribute to Varying Health Responses
Particulate matter in the atmosphere derives from industrial and environmental sources. The size of the particle determines how it deposits in the body and leads to different health challenges.
Rover and Lasers Unlock Clues to Early Martian Atmosphere
Sediments from the Curiosity rover and experiments using tanks of gas and laser beams helped reveal how water continued to flow on Mars after the planet lost its atmospheric carbon dioxide.
Looking at “Night-Shining” Clouds from the Stratosphere
One research group studied noctilucent clouds at large distances from a different point of view, using cameras aboard a meteorological balloon that sailed into the stratosphere.
What Drives Temperature Inversions in the Mesosphere?
A study of nightglow over India reveals that gravity waves are less important than previously thought.
A Simplified Model of Water Vapor Exchange in the Amazon
Evapotranspiration is the exchange of water vapor between land and the atmosphere, and it is hard to measure and model. A new study shows promise for its estimation over large, vegetated landscapes.
