Véronique Meunier

Véronique Meunier (Ph.D (2013), McGill).

I have been a research assistant at the J. S. Marshall Radar Observatory, located near the MacDonald Campus in Ste-Anne-de-Bellevue, since 2014 under the direction of Prof. Frédéric Fabry. My main current research project is the development of a fully scanning microwave radiometer. I am also responsible verifying the calibration and assisting in the maintenance of the S-band radar and other instruments belonging to the Radar Research Group, as well as developing processing software for these data.

Since September 2019, I’m also involved in the new infrastructure deployment Project, an Adaptable Earth-Observation System in the St-Lawrence Valley, under Prof. John Gyakum. I am responsible of the maintenance of the various instruments in several different locations in the St-Lawrence Valley and doing research with the data of these instruments.

Aleksandra Tatarevic

I received an M.Sc. in Atmospheric Science at the Université du Quebec a Montreal (UQAM) in 2008. Since then I have been working as a research assistant at the Department of Atmospheric and Oceanic Sciences of McGill University in the group of Professor Pavlos Kollias.  I have been involved in multiple projects linked to atmospheric sciences funded by the European Space Agency (CASPER, DAME, VARSY, DORSY). I specialized in radar forward models and gained extensive experience in electromagnetic wave propagation and scattering and have a high-level computer and programming qualifications. I have a vast experience in modelling and processor development including retrieval model of the ice cloud microphysics, detailed radar forward simulators and gridding of the radar observables. I have an interest in cloud and precipitation microphysics, numerical modeling, remote sensing and statistical methods.

Since 2015, I am involved in the ESA’s founded DOppler Radar and SYnergy products for EarthCARE (DORSY) project in which I have the role of the EarthCARE Cloud Doppler Profiling Radar (CPR) working-packages manager and lead scientist and work in the team with Dr Wanda Szyrmer and Dr Pavlos Kollias. I am responsible for development of software creating the EarthCARE CPR L2a Feature Mask and Reflectivity (C-FMR) Product, Quality-controlled Doppler Measurements (C-CD) Product, Target Precipitation (C-TC) Product and Cloud and Precipitation Retrieval (C-CLD) Data Product.

I am one of the authors and the main programmer of the following processors written in Fortran that have been released under GNU LESSER GENERAL PUBLIC LICENSE and are available online to scientific community:

 (1) Cloud Resolving Model Radar Simulator (CR-SIM) (  generates the “idealized” forward modelled scanning (or vertical-pointing) Doppler radar observations at different frequencies from the output of Weather Research and Forecasting (WRF) Model (WRF) and for different microphysical packages.

(2) Scanning ARM Cloud Radars (SACR) Processing Package ( for the data quality control and post-processing of ingest data coming from scanning radars operating under Atmospheric Radiation Measurement (ARM) program.

Tizane Peng

Tianze Peng joined the department of AOS at McGill in March 2020 as a two-year postdoctoral researcher to study upper ocean dynamics after obtaining his Ph.D. at the University of Notre Dame in January 2020. He is working with Prof. David Straub on the contributions of a variety of flow regimes to sea surface height (SSH). In this project, Tianze focuses on computational techniques for high-resolution simulations using MITgcm and data analysis for flow diagnostics and decompositions. Before studying the eddying ocean at McGill, Tianze had been working on sea spray in high winds, where he used Eulerian-Lagrangian direct numerical simulations (DNS) to investigate feedback mechanisms of evaporating spray at the air-sea interface.

Quentin Alain Coopman


I am a Postdoctoral researcher in the cloud physics group lead by Ivy Tan in the Department of Atmospheric & Oceanic Sciences at McGill University. My work focuses on the characterization and description of mixed-phase clouds, that are composed of both liquid droplets and ice crystals, in the Arctic. Ground-based and space-based observations in synergy with numerical simulations help to understand mixed-phased clouds, how clouds thermodynamic phase transition from liquid to ice, and the potential impact for the Climate.

Before coming to McGill, I was at the Karlsruhe Institute of Technology as a Postdoctoral researcher in cloud Physics, developing a cloud tracking algorithm from space-based observations to analyse the cloud thermodynamic phase transition. Prior to that, I did my PhD in Atmospheric Science at the University of Utah (USA) and the University of Lille (France) on the aerosol-cloud interaction in the Arctic.
