The impacts of atmospheric radiation on studies of planetary habitability
The conditions required for Earth-like life to emerge on a planet are thought to include the presence of liquid water, the availability of energy, the existence of organic material, and shielding from high energy charged particles. There are situations when determining whether these conditions …

Atmospheric temperature profile retrievals using 54 and 118-GHz spectral observations from the Proteus Aircraft
… phenomenon. Using radiosondes collected from the Atmospheric Radiation Measurement (ARM) Program, a gain and baseline calibration correction was implemented to improve the accuracy of temperature profile retrievals for a particular day. Sensitivity of the NAST-M data was approximately [plus-minus] …

A Numerical Study of the Sensitivity of Cloudy-Scene Bidirectional Reflectivity Distribution Functions to Variations in Cloud Parameters
… for the anisotropic nature of the shortwave radiation field. A shortwave atmospheric radiation Monte-Carlo ray-trace model has been developed as part of this research to predict the earth-reflected radiation field at the top of the atmosphere. This model was developed while paying special …

Energy controls on diurnal snowmelt events and stream recharge, Lost Horse Canyon, Bitterroot Mountains, MT
… this study we compare high frequency (15-minute) atmospheric radiation and its influence on the timing and magnitude of both water table and stream stage fluctuations. We analyze net radiation over the snowpack to approximate the energy state of the snowpack and relate it to hillslope hydrologic …

Non-LTE diagnostics of the infrared observations of the planetary atmosphere
… requires modeling of molecular infrared radiation with accounting for the nonlocal thermodynamic equilibrium (non--LTE). In this dissertation a general formulation is given of the multilevel vibrational-rotational non-LTE problem for a mixture of radiating molecular gases in a planetary …

Four problems in nonlinear Earth system dynamics
… the deep geologic past. Using a simple model of atmospheric radiation and the weathering feedback, I show that the most relevant “tipping point” leading to glaciation may be a critical rate of decrease in effective solar radiation, as could result from volcanic aerosols or the collapse of a …

Three-dimensional water vapor retrieval using a network of scanning compact microwave radiometers
… Recently, field measurements at the DOE Atmospheric Radiation Measurement (ARM) Southern Great Plains site in Oklahoma have demonstrated the potential for coordinated, scanning microwave radiometers to provide 0.5-1 km resolution both vertically and horizontally with sampling times of 15 …

Ionizing radiation effects spectroscopy
… Various stresses, such as exposure to ionizing radiation and extreme temperatures can result in performance degradation, transient anomalies, and hard failures. These issues have become evident in recent years with the increasing interest in the use of commercial-off-the-shelf (COTS) electronics …
