The past half century has seen an unprecedented growth of the world’s urban population. While areas proffer highest quality life, they also inflict environmental degradation that pervades a multitude space-time scales. In atmospheric context, stressors human (anthropogenic) origin are mainly imparted on lower atmosphere and communicated to regional, global, smaller scales via transport turbulence processes. Conversely, changes in all transmitted regions through atmosphere. fluid dynamics...

This study investigates long-term (i.e., 2007–2014) fluctuations in ambient ozone formation regimes for cities adjacent to shale plays the Northeast United States (U.S.). Ozone air quality many of U.S. does not meet National Ambient Air Quality Standards (NAAQS), and understanding is essential develop effective pollution mitigation strategies violating standards. Since 2013, has become world’s largest producer tight oil natural gas from rock, previous studies show that emissions pollutant...

Abstract Past research has suggested that the evening transition in complex topography typically several main features, such as (a) continued weak upslope flows persisting 3–5 h after sunset (if sidewalls of valley prevent Coriolis-induced turning winds), thus signifying delayed transition; (b) unsteady local stagnation and vertical mixing within tens meters above surface; (c) fronts to downslope/downvalley gravity currents during hours, especially at higher-elevation (steeper) slopes, their...

Studies, public reports, news and Web sites cite a wide range of values associated with deaths resulting from excessive heat cold. For example, in the United States, National Climatic Data Center's Storm statistics temperature-related are skewed heavily toward heat-related deaths, while Center for Health Statistics Compressed Mortality Database indicates reverse—4 times more people die "excessive cold" conditions given year than heat." In this study, we address fundamental differences...

Fixed stations versus automobile transects were compared for a 27-day period between July and November 2001 to investigate urban, residential, rural temperatures dew points post-sundown sub-region in the metropolitan area of Phoenix, Arizona. Temperature point differences determined among urban (urb), residential (res), (rur) from fixed sites (fix) mobile transect route (tran). On average, revealed mean ΔT(urb-rur)tran 7.3°C (standard deviation, σ, 2.02°C) ΔT(res-rur)tran 3°C (σ = 1.09°C);...

Abstract. Statistically significant correlations between increase of asthma attacks in children and elevated concentrations particulate matter diameter 10 microns less (PM10) were determined for metropolitan Phoenix, Arizona. Interpolated from a five-site network provided spatial distribution PM10 that was mapped onto census tracts with population health records. The case-crossover statistical method applied to determine the relationship concentration attacks. For ages 5–17, discovered two,...

The application of unmanned aerial vehicles (UAVs) in the monitoring and management rangelands has exponentially increased recent years due to miniaturization sensors, ability capture imagery with high spatial resolution, lower altitude platforms, ease flying UAVs remote environments. aim this research was develop a method estimate forage mass using high-resolution derived from UAV South Texas pasture as pilot site. specific objectives were (1) evaluate feasibility quantifying semi-arid...

Much work has been done to understand and improve soil water conservation where agriculture driven land use intensification. Less is known about soil- water-related impacts from intensification by solar farming, especially at watershed-scales. Here we employed Hydrologic Engineering Center's Modeling System (HEC-HMS) model Pond Creek, a rural watershed in Texas, USA. Land primarily crop cultivation secondarily pasture for cattle grazing. Presently, several industrial-scale projects are...

The purpose of this study was to determine the spatial and temporal aspects urban heat island in small, arid city Casa Grande, Arizona. Temperature dewpoint were collected through a combination fixed stations two mobile transect routes on four separate clear calm nights during period 15–18 March 2004. A 18 revealed maximum difference 4.7°C along an east-to-west route across city, with spatially interpolated temperature map illustrating warmest areas far eastern commercial corridor cooler...
