Understanding Exoplanet Atmospheres with UV Observations II: The Far UV and Atmospheric Escape [PDF]

open access: yesarXiv, 2019
Much of the focus of exoplanet atmosphere analysis in the coming decade will be at infrared wavelengths, with the planned launches of the James Webb Space Telescope (JWST) and the Wide-Field Infrared Survey Telescope (WFIRST). However, without being placed in the context of broader wavelength coverage, especially in the optical and ultraviolet ...

Methods for working with problem residents in medical physics residency education

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Medical physics residency training programs may occasionally encounter residents requiring additional intervention beyond normal training efforts. In the literature, these residents are referred to as “problem” residents. While the physician literature on the subject is valuable, this paper specifically focuses on dealing with a problem ...

Performance Triggered Adaptive Model Reduction for Soil Moisture Estimation in Precision Irrigation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT Accurate soil moisture information is essential for precise irrigation to enhance water use efficiency. Estimating soil moisture based on limited soil moisture sensors is especially critical for obtaining comprehensive soil moisture information when dealing with large‐scale agricultural fields.

A Stochastic Diffusion Model of Climate Change [PDF]

open access: yesarXiv, 1995
We present a model for variations in atmospheric temperature from time scales of one day to one million years based on a stochastic diffusion (random walk) model of the turbulent transport of heat energy vertically in a coupled atmosphere-ocean model.

Remote sensing of clouds and aerosols with cosmic rays [PDF]

open access: yes, 2014
Remote sensing of atmosphere is conventionally done via a study of extinction / scattering of light from natural (Sun, Moon) or artificial (laser) sources. Cherenkov emission from extensive air showers generated by cosmic rays provides one more natural light source distributed throughout the atmosphere.

Stormy water on Mars: The distribution and saturation of atmospheric water during the dusty season

open access: yesScience, 2020
Water reaches Mars' upper atmosphere Mars once hosted abundant water on its surface but subsequently lost most of it to space. Small amounts of water vapor are still present in the atmosphere, which can escape if they reach sufficiently high altitudes ...
