Modelling the atmospheric oxidised and reduced nitrogen budgets for the UK with a Lagrangian multi-layer long-range transport modelSpringer Science and Business Media LLC - Tập 5 - Trang 83-104 - 2000
D.S. Lee, R.D. Kingdon, M.E. Jenkin, J.A. Garland
The United Kingdom budgets of oxidised and reduced nitrogen (N) species, major components of acidic deposition, are analysed with a long-range transport model. In order to describe adequately the surface sources of trace species, a simple description of vertical diffusion has been incorporated, along with a multiple resistance dry deposition velocity scheme. Also, a fully diurnal chemical scheme i...... hiện toàn bộ
Convergence in Sulphur Dioxide (SO2) Emissions Since 1850 in OECD Countries: Evidence from a New Panel Unit Root TestSpringer Science and Business Media LLC - Tập 25 - Trang 665-675 - 2019
Sakiru Adebola Solarin, Aviral Tiwari
The convergence of air pollution is a key assumption in several environmental impact assessment models and one of the major ingredients for multilateral climate agreements and allocation of emission rights. In this paper, the sulphur dioxide (SO2) emissions’ convergence among 32 OECD countries is examined using the panel stationarity test of Nazlioglu and Karul [1] that provides for smooth breaks,...... hiện toàn bộ
Phân Tích Đa Hồi Quy và Đa Cộng Tuyến cho Những Nhân Tố Chính Gây Ra Tảo Nở Phát Triển Độc Hại (CHAB) Tại Hồ Torment, Nova Scotia, Canada Dịch bởi AI Springer Science and Business Media LLC - Tập 28 - Trang 1011-1022 - 2023
Kateryna Hushchyna, Qurat Ul An Sabir, Kayla Mclellan, Tri Nguyen-Quang
Có nhiều tham số liên quan đến mô hình bùng phát của vi sinh vật lam trong hồ Torment. Điều này bao gồm các thành phần hóa học, cụ thể là TP, PO4-P, NO3-N, NH4-N và sắt, v.v. Tuy nhiên, nếu tồn tại hiện tượng đa cộng tuyến trong các yếu tố liên quan đến mô hình CHAB với một phụ thuộc gần tương tự tuyến tính mà trong đó hai hoặc nhiều biến dự báo có tương quan cao với nhau, chúng tôi thường không t...... hiện toàn bộ
A Time-Dependent System for Evaluating Groundwater Contamination Hazard Rating of Municipal Solid Waste DumpsSpringer Science and Business Media LLC - Tập 15 - Trang 549-567 - 2010
Raj Kumar Singh, Manoj Datta, Arvind Kumar Nema
In developing countries, several old municipal solid waste dumps (unlined landfills) exist adjacent to large cities, releasing contaminants to the underlying aquifer, thus posing the hazard of groundwater contamination. These uncontrolled waste dumps need to be prioritized in terms of the groundwater contamination hazard posed by them, so that necessary control and remedial measures can be underta...... hiện toàn bộ
Energy Price Jumps, Fat Tails and Climate PolicySpringer Science and Business Media LLC - Tập 27 - Trang 993-1005 - 2021
Charles F. Mason, Neil A. Wilmot
Many authors who have analyzed key energy prices, such as crude oil and natural gas, have found that these prices exhibit “fat tails”—the feature that large percentage changes occur far more often than would be predicted by a conventional model. These fat tails can arise either because of time-varying volatility or because of rapid, unexpected changes—also known as jumps. Addressing global climate...... hiện toàn bộ
Can we integrate climatic modelling and assessment?Springer Science and Business Media LLC - Tập 1 - Trang 59-70 - 1996
A. Henderson-Sellers
The climatic change “debate” seems to be expanding faster than the available information base. National and international response strategies (mitigation and adaptation) are being discussed in board rooms, governments and the media. Phrases like “the uncertainty in the scenarios” appear to carry meaning but the information seems to be, at best, incomplete and, at worst, totally debased by multiple...... hiện toàn bộ
