Autor: N. T. O'Neill, K. Ranjbar, L. Ivănescu, T. F. Eck, J. S. Reid, D. M. Giles, D. Pérez-Ramírez, J. P. Chaubey

Publikováno v: Atmospheric Measurement Techniques, Vol 16, Pp 1103-1120 (2023)

The sub-micron (SM) aerosol optical depth (AOD) is an optical separation based on the fraction of particles below a specified cutoff radius of the particle size distribution (PSD) at a given particle radius. It is fundamentally different from spectra

Characterizing the hygroscopicity of growing particles in the Canadian Arctic summer

Autor: R. Y.-W. Chang, J. P. D. Abbatt, M. C. Boyer, J. P. Chaubey, D. B. Collins

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 8059-8071 (2022)

The impact of aerosols on clouds is a well-studied, although still poorly constrained, part of the atmospheric system. New particle formation (NPF) is thought to contribute 40 %–80 % of the global cloud droplet number concentration, although it is

Measurement report: The chemical composition of and temporal variability in aerosol particles at Tuktoyaktuk, Canada, during the Year of Polar Prediction Second Special Observing Period

Autor: J. MacInnis, J. P. Chaubey, C. Weagle, D. Atkinson, R. Y.-W. Chang

Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 14199-14213 (2021)

The chemical composition, sources, and concentrations of aerosol particles vary on a seasonal basis in the Arctic. While existing research has focused on understanding the occurrence of aerosol particles during the Arctic winter and spring, less is k

Temporal and spectral cloud screening of polar winter aerosol optical depth (AOD): impact of homogeneous and inhomogeneous clouds and crystal layers on climatological-scale AODs

Autor: N. T. O'Neill, K. Baibakov, S. Hesaraki, L. Ivanescu, R. V. Martin, C. Perro, J. P. Chaubey, A. Herber, T. J. Duck

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 12753-12765 (2016)

We compared star-photometry-derived, polar winter aerosol optical depths (AODs), acquired at Eureka, Nunavut, Canada, and Ny-Ålesund, Svalbard, with GEOS-Chem (GC) simulations as well as ground-based lidar and CALIOP (Cloud-Aerosol Lidar with Ort

The optical and physical properties of atmospheric aerosols over the Indian Antarctic stations during southern hemispheric summer of the International Polar Year 2007–2008

Autor: J. P. Chaubey, K. Krishna Moorthy, S. Suresh Babu, V. S. Nair

Publikováno v: Annales Geophysicae, Vol 29, Pp 109-121 (2011)

The properties of background aerosols and their dependence on meteorological, geographical and human influence are examined using measured spectral aerosol optical depth (AOD), total mass concentration (MT) and derived number size distribution (NS
