Evaluation of regional jet operating patterns in the Continental United States
Airlines are increasingly using regional jets to better match aircraft size to high value, but limited demand markets. The increase in regional jet usage represents a significant change from traditional air traffic patterns. To investigate the possible impacts of this change on the air traffic …

Establishing Monetary Valuation Methods for Forested Riparian Wetlands in the Continental United States
Forested floodplains were seen by early European settlers as areas to be exploited for timber, then drained for agricultural use of their fertile soils. Government programs were designed for federally subsidizing this land use conversion, and more than half of these ecosystems were indeed destroyed …

Evaluations of historical and projected high-resolution dynamically downscaled ensemble over the continental United States
… project changes in the climate system at a continental scale, but lack the spatial resolution needed to represent mesoscale processes that affect regional climate extremes. To rectify this limitation, a technique known as dynamically downscaling was introduced to better resolve these …

Using statistical learning approaches to understand trends and variability of tornadoes across the continental United States
… 1950-2018 across the major tornado-impacted states were examined and modeled using anthropogenic and large-scale climate covariates in a hierarchical Bayesian inference framework. Anthropogenic factors include increases in population density and better detection systems since the mid-1990s. …

A Computer Model to Estimate Commercial Aviation Fuel Consumption and Emissions in the Continental United States
… emissions by domestic commercial aviation in the Continental United States. Most of the existing fuel consumption and emission models are limited in their ability to predict the annual fuel burn for air transportation at the national level. For example, those models either require real track data …
