The overarching theme of my research is chemistry and physicochemical properties of aerosol particles and their impacts on air quality, health, climate, and biogeochemical cycles. This is achieved via laboratory studies and field measurements, as well as active collaborations with modelers. Since I am a graduate student I have been working in the following fields: 1) atmospheric multiphase chemistry; 2) hygroscopicity and ice nucleating properties of aerosol particles; 3) sources, processes and solubility of aerosol trace elements.

My research group strives to be a world leader in the measurement of volatile organic compounds and the interpretation and synthesis of these measurements in the full context of atmospheric chemistry. A main goal of my research activity is to participate in collaborative efforts to quantify the chemical composition of the atmosphere, characterize how it is changing in response to natural and anthropogenic forcings, and, ultimately, develop the capability to predict changes that may have important implications for the health of the Earth’s ecosystem. I have acquired expertise in the development and deployment of novel instrumentation to measure a suite of volatile organic compounds (non-methane hydrocarbons, oxygenated volatile organic compounds, and CFCs and HCFCs) that directly impact the chemistry of the troposphere and lower stratosphere. I place a special emphasis on the interpretation of these measurements with respect to their impact on cycles of NOx, HOx and halogens. I have led the development of the unique and highly successful Trace Organic Gas Analyzer (TOGA). TOGA quantifies a full suite of the VOCs listed above in near-real-time at unprecedented levels of accuracy, precision and speed on multiple platforms, including the NCAR GV, and C-130 aircraft, as well as the NASA DC-8. Recently I led the development of the Trace Organic Gas Analyzer - Time-of-Flight Mass Spectrometer (TOGA-TOF). This is the most advanced Fast GC-MS TOF instrument in the world. It was recently deployed on the NASA DC-8 for the FIREX-AQ mission. I recently led the development of the WASPP – the NCAR ACOM Whole Air Sampler Pilotless Platform, a unique and versatile atmospheric sampling drone system developed during Lizzy Asher’s ASP Postdoc.

I have been working on stratospheric chemistry and dynamics for about 20 years. My primary interest is exploiting satellite data sets to improve our understanding about the chemical and dynamical processes in the atmosphere. My primary tools are chemical models and statistical techniques to quantify influence of various climate forcers (e.g. Volcanos/solar variability). I also use machine learning to construct long-term gap free datasets.

Since 2006, Dr. Dubovik works in the Laboratoire d'Optique Atmosphérique, Université Lille, France as CNRS “Research Director”. Main scientific accomplishments of Dr. Dubovik include following developments: - aerosol retrieval algorithm for AERONET federated network of ground-based radiometers (https://aeronet.gsfc.nasa.gov)- one of pioneering climatologies of absorption and optical properties of ambient tropospheric aerosol; - popular efficient software for modeling scattering by non-spherical aerosol particles. Dr. Dubovik focuses on refinement of methodological aspects of numerical inversion for needs of remote sensing by applying elaborated statistical optimization approach. The developed principles were recently realized GRASP open source algorithm (https://www.grasp-open.com/) that can be applied to retrieval detailed aerosol properties fro diverse observations including both passive and active observations from satellite or ground. For example, GRASP is used in multiple algorithm development for deriving extended set of parameters from ground-based observations by lidar and radiometer (e.g., in operational processing frame of European ACTRIS infrastructure) satellite observations by POLDER-1,-2,-3, MERIS and AATSR/Envisat, Sentinel -3, -4, -5P, 3MI/EPS-SG, MAP/CO2M, etc.

My major research fields include Atmospheric Chemistry and Environmental Sciences. I developed novel techniques to accomplish accurate measurements of OH, total OH reactivity, HO2, RO2, O3, NO, NO2, NO3, N2O5 and HONO in chemically complex air environments as well as simulated conditions in the lab. I focused on the sources, transformations and chemical mechanisms of atmospheric free radicals in typical urban areas, and aims to quantify the formation mechanism of regional secondary pollution from the chemical perspective, providing scientific and technological support for the control of regional secondary pollution.

The overarching theme of my research is chemistry and physicochemical properties of aerosol particles and their impacts on air quality, health, climate, and biogeochemical cycles. This is achieved via laboratory studies and field measurements, as well as active collaborations with modelers. Since I am a graduate student I have been working in the following fields: 1) atmospheric multiphase chemistry; 2) hygroscopicity and ice nucleating properties of aerosol particles; 3) sources, processes and solubility of aerosol trace elements.

In general terms, my research interest could best be described as data quality assessment, uncertainty estimation and data homogenization with the purpose to study the variation in data series due to climate change processes. I am in particular interested in the variation of water vapour and ozone, both the total column values as the vertical profiles. I developed, applied and compared different correction strategies for vertical profiles of humidity and ozone and I undertook a multi-site intercomparison of total column water vapour measurements at almost 30 sites worldwide by 5 different techniques. Currently, I devote most of my time advertising the use of GPS total column water vapour measurement for climate applications and the controlling the quality assessment of the worldwide network of ozonesonde measurements.
