Eye of the storm: Observing hurricanes with a small unmanned aircraft system
Unique data from seven flights of the Coyote small unmanned aircraft system (sUAS) were collected in Hurricanes Maria (2017) and Michael (2018). Using NOAA's P-3 reconnaissance...- publication PDF

Tropical decadal variability and the rate of Arctic Sea ice decrease
The trend for cold-season (November-December-January-February, NDJF) decreases in Arctic sea ice extent from 2000 to 2014 was about a factor of two larger than the 1979-2000...- publication PDF

Condensational growth of drops formed on giant sea-salt aerosol particles
The most basic aspect of cloud formation is condensational growth onto cloud condensation nuclei (CCN). As such, condensational growth of cloud drops is often assumed to be a...- publication PDF

Measurement of atmospheric sesquiterpenes by proton transfer reaction-mass...
The ability to measure sesquiterpenes (SQT; C₁₅H₂₄) by a Proton-Transfer-Reaction Mass Spectrometer (PTR-MS) was investigated. SQT calibration standards were prepared by a...- publication PDF

Simulations of the ionospheric annual asymmetry: Sun-Earth distance effect
It has been suggested that the difference of the Sun-Earth distance between the December and June solstices has a great impact on the ionospheric annual asymmetry. In this...- publication PDF

High-cadence visible and infrared spectra of the Sun during eclipse
We study novel spectra from 310 nm to 5.5 mu m obtained during the 2017 August 21 eclipse. Four spectrometers were deployed at Camp Wyoba (altitude 2402 m) on Casper Mountain,...- publication PDF

Hydrodynamic planetary thermosphere model: 1. Response of the Earth's...
It has been suggested that the exobase temperature of early terrestrial planetary atmosphere could have reached over 10,000 K. Although such high exobase temperatures should...- publication PDF
