Acid inputs from the atmosphere in the United Kingdom

Soil Use and Management, 1985
Abstract. Inputs of acidity to the ground arise through two distinct routes: wet deposition which includes all acidity deposited in rain and snow and dry deposition, the direct sorption of SO 2 , NO 2 or HNO 3

Variations of atmospheric temperature with altitude in the United States

Electrical Engineering, 1941
It has long been recognized that with increase in altitude the density of air decreases and influences the voltage rating and temperature rise of electrical apparatus. However, different standards for apparatus do not give the same weight to these factors.

Symbols, Units and Nomenclature for Atmospheric Transmission

Optical Engineering, 1966
This report discusses concepts, symbols, units and nomenclature for describing the transmission of radiant flux through earth's variable density atmosphere. The geometrical concepts used in the field of photometry and radiometry are the same. A common set of symbols is proposed for use in both fields together with some terms not previously used.

Polychlorinated Naphthalenes in the Atmosphere of the United Kingdom

Environmental Science & Technology, 2000
Archived extracts from two air sampling campaigns were used to investigate PCNs in the U.K. atmosphere. In the first study, daily air samples were collected at a semi-rural location (Hazelrigg) in northwest England in 1994. Air parcel back-trajectories were used to distinguish air masses that stemmed from distinct sectors, and 18 samples representing ...

ATMOSPHERIC WAVES IN THE NORTHWESTERN UNITED STATES

Journal of Meteorology, 1948
Abstract I. The flow of air in vertical planes across the Rocky Mountains is studied through the potential-temperature distribution. Sinusoidal configurations of the isentropes are observed which seem to correspond to theoretical patterns, i.e., wide separation of isentropic surfaces (low stability) and ascent overlying descent in the lee with a nodal ...

Atmospheric polybrominated diphenyl ethers (PBDEs) in the United Kingdom

Environmental Pollution, 2012
The occurrence of PBDEs has been studied in the atmosphere of four sites in the United Kingdom over a period of ten years. The concentrations have exhibited a sharp decrease after 2001-2003. This is evident in the urban sites of Manchester and London and at the semi-rural site of Hazelrigg. The average ΣPBDE half-lives for these three sites were 3.4, 2.

A Sub-Atmospheric Solar Distillation Unit

International Journal of Solar Energy, 1987
Abstract This paper describes the design, manufacture and performance of a new type of solar distillation unit. The unit operates at a pressure below the atmospheric and utilizes a flat-plate collector. The designed unit is intended for an experimental purpose and operates on draw and fill or non-flow basis.

Trends in atmospheric reactive nitrogen for the Eastern United States

Environmental Pollution, 2011
Reactive nitrogen can travel far from emission sources and impact sensitive ecosystems. From 2002 to 2006, policy actions have led to decreases in NO(x) emissions from power plants and motor vehicles. In this study, atmospheric chemical transport modeling demonstrates that these emissions reductions have led to a downward trend in ambient measurements ...

Unit 3.2 Why are there layers of the atmosphere?

This educational module page explores atmospheric layering through inquiry-based activities, covering air pressure, temperature gradients, and density, with guided lab exercises, data analysis using real radiosonde datasets, and demonstrations like cloud-in-a-bottle to explain stratification and weather phenomena for introductory college-level physical
