Large Amounts of Water Vapor Were Injected into the Stratosphere by the Hunga Tonga–Hunga Ha’apai Volcano Eruption

Atmosphere, 2022
The Hunga Tonga–Hunga Ha’apai (Tonga) injected only small amount of SO2 into the stratosphere, while our analyses of the Microwave Limb Sounder (MLS) measurements show that a massive amount of water vapor was directly injected into the stratosphere by ...

Visual Observations of the Solar Atmosphere [PDF]

Proceedings of the National Academy of Sciences, 1926
The spectrohelioscope, an instrument for observing the sun in monochromatic light, has been briefly described in a previous article. (1) The same optical parts employed in the preliminary work are now rigidly mounted in a vertical position in my new Solar Laboratory in Pasadena (a branch of the Mount Wilson Observatory).

Direct Observations of Atmospheric Aerosol Nucleation

Science, 2013
Aerosol Formation Most atmospheric aerosol particles result from a growth process that begins with atmospheric molecules and clusters, progressing to larger and larger sizes as they acquire other molecules, clusters, and particles.

A New Hybrid Algorithm to Image Lightning Channels Combining the Time Difference of Arrival Technique and Electromagnetic Time Reversal Technique

Remote Sensing, 2021
Very-high-frequency (VHF) electromagnetic signals have been well used to image lightning channels with high temporal and spatial resolution due to their capability to penetrate clouds.

Observation of Atmospheric Neutrinos [PDF]

Universe, 2020
In 1998, the Super-Kamiokande discovered neutrino oscillation using atmospheric neutrino anomalies. It was the first direct evidence of neutrino mass and the first phenomenon to be discovered beyond the standard model of particle physics. Recently, more precise measurements of neutrino oscillation parameters using atmospheric neutrinos have been ...

Observations of Exoplanet Atmospheres [PDF]

Publications of the Astronomical Society of the Pacific, 2015
Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and disequilibrium processes.

Characterizing Transitions between Successional Stages in a Tropical Dry Forest Using LiDAR Techniques

Remote Sensing, 2023
Secondary succession is defined as natural regeneration following complete forest clearance from anthropogenic or natural disturbances. Traditional strategies aimed to map and characterize secondary succession using remote sensing are usually based on ...
