In the News: Global warming felt to deepest reaches of ocean

Our very own Jaime Palter and Casimir de Lavergne are making waves with a new article titled Cessation of deep convection in the open Southern Ocean under anthropogenic climate change.

Read more about it in the McGill NewsRoom.

New Software: HDFView

HDFView is now available ! To use HDFView, please issue ‘hdfview’ on all 64-bit computers in our department.

HDFView Screenshot

HDFView is a visual tool for browsing and editing HDF4 and HDF5 files. Using HDFView, you can:

  • >view a file hierarchy in a tree structure
  • create new file, add or delete groups and datasets
  • view and modify the content of a dataset
  • add, delete and modify attributes
  • replace I/O and GUI components such as table view, image view and metadata view

Happy Holidays from AOS

With every new year it is often rewarding to look back at the past one and note all of the achievements and changes that were made.  The department of Atmospheric and Oceanic Sciences did just that and producred a holiday newsletter looking back at the past year. Please have a look!

We wish you and your family happy holidays!

Seminar: Dr. King-Fai Li

Dr. King-Fai Li of the Division of Geological and Planetary Sciences from the California Institute of Technology and Department of Applied Mathematics, University of Washington will be presenting a seminar today at 1pm in Burnside Hall 934.

Abstract

A persistent discrepancy between the model and observed stratospheric O3 solar response is revisited using the Whole-Atmosphere Community Chemistry Model (WACCM). The model O3 simulated using UV irradiances measured from the latest spaceborne solar UV measurements by the Solar Radiation and Climate Experiment (SORCE) and that from the solar UV parametrization developed by the Naval Research Laboratory (NRL) are studied and compared with observations. None of the simulations using SORCE and NRL UV simultaneously agree with the observed O3 solar response in both upper and lower stratospheres, thus presenting a dilemma to our current understanding of stratospheric O3 response to UV perturbations. However, the simulation using the SORCE UV irradiance leads to a solar response in upper stratospheric/lower mesospheric OH column that agrees better that those derived from ground-based and satellite observations. Continuous long-term observations of solar UV, OH, O3 and other related chemical species through upcoming solar cycles are crucial for further investigations to solve these above puzzles.

Welcome to our Blog

Welcome to McGill’s Department of Atmospheric and Oceanic Science blog. We are the largest university atmospheric-oceanic sciences group in Canada. We have academic programs at both the undergraduate and graduate levels, covering a broad range of topics, ranging in scale from the microphysics of raindrops to the global circulation patterns observed in the atmosphere and oceans. We currently has over 40 undergraduate and over 50 graduate students, many of whom come from abroad.

We have a rich history, and have leaders in various fields of atmospheric science and physical oceanography. Many of the researchers in our department are members of the The Global Environmental and Climate Change Centre and work on climate change problems. Graduates of our various programs move forward to have careers in industry, government and academia.

It is our hope that this blog will allow you to follow the many new and exciting discoveries that are taking place in the realm of atmospheric and oceanic science as well as let you remain up to date about the comings and goings of our dynamic department.
