Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Meteorology
  • Aerosol

James Allan mainly focuses on Aerosol, Mass spectrometry, Meteorology, Environmental chemistry and Particulates. James Allan specializes in Aerosol, namely Aerosol mass spectrometry. As a part of the same scientific study, James Allan usually deals with the Mass spectrometry, concentrating on Chemical transport model and frequently concerns with Monoterpene and Parts-per notation.

In Meteorology, he works on issues like Soot, which are connected to Dispersion. His Environmental chemistry research integrates issues from NOx, Volatile organic compound and Ultrafine particle. James Allan combines subjects such as Organic matter and Cloud condensation nuclei with his study of Particulates.

His most cited work include:

  • Evolution of Organic Aerosols in the Atmosphere (2184 citations)
  • Ubiquity and dominance of oxygenated species in organic aerosols in anthropogenically-influenced Northern Hemisphere midlatitudes (1380 citations)
  • Chemical and microphysical characterization of ambient aerosols with the aerodyne aerosol mass spectrometer (1161 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of study are Aerosol, Atmospheric sciences, Environmental chemistry, Particulates and Meteorology. Specifically, his work in Aerosol is concerned with the study of Aerosol mass spectrometry. His Atmospheric sciences study integrates concerns from other disciplines, such as Atmosphere, Air pollution, Climatology and Air quality index.

His research integrates issues of Ammonium, Sea salt, Nitrate and Volatile organic compound in his study of Environmental chemistry. James Allan interconnects Combustion, NOx, Organic matter and Sulfate in the investigation of issues within Particulates. James Allan studies Meteorology, namely Radiative forcing.

He most often published in these fields:

  • Aerosol (62.84%)
  • Atmospheric sciences (38.67%)
  • Environmental chemistry (23.87%)

What were the highlights of his more recent work (between 2016-2021)?

  • Aerosol (62.84%)
  • Atmospheric sciences (38.67%)
  • Particulates (18.43%)

In recent papers he was focusing on the following fields of study:

His main research concerns Aerosol, Atmospheric sciences, Particulates, Environmental chemistry and Soot. James Allan is interested in Radiative forcing, which is a branch of Aerosol. His work in the fields of Troposphere overlaps with other areas such as Mass concentration.

His research in Particulates is mostly focused on Aerosol mass spectrometry. His Environmental chemistry research is multidisciplinary, incorporating perspectives in Chlorine, Volatile organic compound, Mass spectrometry, Haze and Nitrate. His work on Mass spectrum as part of his general Mass spectrometry study is frequently connected to Apportionment, thereby bridging the divide between different branches of science.

Between 2016 and 2021, his most popular works were:

  • Black-carbon absorption enhancement in the atmosphere determined by particle mixing state (149 citations)
  • Introduction to the special issue "in-depth study of air pollution sources and processes within Beijing and its surrounding region (APHH-Beijing)" (56 citations)
  • Vertical characterization of aerosol optical properties and brown carbon in winter in urban Beijing, China (38 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Meteorology
  • Aerosol

James Allan mostly deals with Aerosol, Atmospheric sciences, Environmental chemistry, Absorption and Soot. His research in Aerosol intersects with topics in Atmosphere, Climate model, Particulates, Sulfate and Haze. Particularly relevant to Troposphere is his body of work in Atmospheric sciences.

The study incorporates disciplines such as Reagent, Chlorine and Mass spectrometry in addition to Environmental chemistry. His Mass spectrometry research incorporates elements of Photodissociation, Ionization, Nitrous acid and Spectrometer. His studies deal with areas such as Photometer and Analytical chemistry as well as Absorption.
