Evolution of Radar and Lightning Variables in Convective Events in Barcelona and Surroundings for the Period 2006–2020

Received: 28 October 2020;  Published: 14 April 2021;  doi: 10.21926/aeer.2102004

Abstract

The Metropolitan Area of Barcelona is a very densely populated region in the NE of the Iberian Peninsula. Besides, infrastructures in the area have a concrete height in the economy of this part of Europe. The combination of the Mediterranean Sea and the complex topography plays a role in the occurrence of severe weather events in this area and its surrounding. The use of remote sensing data in an hourly resolution allows the identification and characterization of those severe episodes, helping to determine the futu [...]

Linking Population and Forest Dynamics over the Conterminous US for the 1990s and 2000s

Received: 24 September 2020;  Published: 09 March 2021;  doi: 10.21926/aeer.2101003

Abstract

Few studies have investigated deforestation and population connections in the U.S. at large spatial extents or small scales. We examined forest cover changes over two decades, 1990-2000 and 2000-2010, in the continental U.S. at the county scale. Forest dynamics were estimated using the National Land Cover Database, a satellite-derived classification product and then linked to population data from the US. Census. At the aggregate level, high population growth seems to increase net forest loss in a non-linear manner, [...]

Impact of Covid-19 Pandemic on Air Transport: Overview and Implications

Received: 16 December 2020;  Published: 22 February 2021;  doi: 10.21926/aeer.2101002

Abstract

The current situation of the COVID-19 pandemic has led to multiple changes in the international market as well as in the lifestyle of people worldwide. The transport sector has undoubtedly been one of the most affected sectors due to restrictions imposed by the governments across the world to protect the health of their citizens, particularly the restrictions imposed on the operation of airlines. On the other hand, the reduction in travel by means of transport has contributed in part to the improvement in the envir [...]

Interactions of Per- and Polyfluoralkyl Substances (PFAS) with Landfill Liners

Received: 16 September 2020;  Published: 31 December 2020;  doi: 10.21926/aeer.2004007

Abstract

This review synthesises the available published research on interactions of per- and polyfluoroalkyl substances (PFAS) with landfill liners, with the view to inform on the expected behaviour of these persistent environmental pollutants in landfills. The review addresses the nature and significant types of PFAS compounds that are destined for landfills, as well as their by-product. It discusses the known and anticipated interactions with separate landfill liner components, namely geomembranes, geosynthetic clay line [...]

Electrochemical Oxidation of Perfluorooctanesulfonate by Magnéli Phase Ti4O7 Electrode in the Presence of Trichloroethylene

Received: 02 November 2020;  Published: 29 December 2020;  doi: 10.21926/aeer.2004006

Abstract

This study examined the degradation of perfluorooctanesulfonate (PFOS) in electrochemical oxidation (EO) processes in the presence of trichloroethylene (TCE). The EO experiment was performed in a gas-tight reactor using Magnéli phase titanium suboxide (Ti4O 7) as the anode. The experimental data demonstrated that 75% of PFOS (2 μM) was degraded at 10 mA/cm2 current density in 30 min without TCE present in the solution, while the presence of 76 μM TCE apparently inhibited the degradati [...]

How to Prioritize Voluntary Dietary Modification

Received: 03 August 2020;  Published: 25 December 2020;  doi: 10.21926/aeer.2004005

Abstract

Environmentally motivated voluntary diet modifications are the focus of much research and public discourse. Yet the nuanced multi-faceted, multi-dimensional nature of agriculture-earth interactions, and limited public environmental knowledge likely combine to undermine the efficacy of environmentally motivated dietary shifts, squandering limited good will. To counter this, here I devise two related indices for crudely estimating importance of various environmental impacts of alternative dietary choices. Based on th [...]

Climate Cloud Model Forecast Verification-an Engineering Perspective

Received: 13 September 2020;  Published: 24 November 2020;  doi: 10.21926/aeer.2004004

Abstract

The processes relevant to the verification of cloud forecasts generated by climate models are discussed from an engineering perspective. These processes include an assessment of cloud product requirements to be evaluated, the creation of a verification test plan including procedures and data to be analyzed, the development of independent sources of validation or truth datasets, and the quantitative comparisons between the cloud forecast products and the truth data needed to establish model performance. The engineer [...]

Impact of COVID-19 Lockdowns and Australian Bushfires on Aerosol Loading over the Downwind Oceanic Regions

Received: 21 August 2020;  Published: 23 November 2020;  doi: 10.21926/aeer.2004003

Abstract

Nearly 40 years of aerosol optical thickness (AOT) climate data record (CDR) from AVHRR satellite observations over the global ocean is used to study the impact of COVID-19 lockdowns and Australian bushfires on aerosol loading over downwind oceanic regions. Recent similar impact studies, by contrast, were mainly focused on the urban and suburban areas near the emission sources. AOT is used as a proxy for aerosol loading in our study. We found that AOT variations due to anthropogenic emission reduction during the lo [...]

Estimating the Intensity of Hurricanes from Historical Radar Data Using the Hyperbolic-logarithmic Approximation of Spiral Rainbands

Received: 28 July 2020;  Published: 10 November 2020;  doi: 10.21926/aeer.2004002

Abstract

To increase the amount of information on the intensities of tropical cyclones (TC) used in climate research, the possibility of additional estimates of the intensity of a TC by exploring historical data of conventional (non-Doppler) airborne and coastal radars is considered. Based on the hyperbolic-logarithmic spiral (HLS) model of the streamline in the TC, an assessment of the maximum wind speed in hurricanes Cleo (1958), Carolina (1975) and Alicia (1983) was made. Literature sources containing radar signatures of [...]
