Visibility Forecast in Wildfire Smoke: An August 2018 Case Study

– By Yimei Li, Canadian Meteorological Aviation Centre, Environment and Climate Change Canada –

In recent years, wildfire smoke has become an increasingly alarming natural disaster in Western Canada. In 2017 and 2018, the British Columbia provincial government declared a state of emergency for two consecutive summers in response to the wildfire situation (1). These were the third and fourth declarations in history and the previous ones were in 1996 and 2003.

Blue Sky Blues or the Three Degrees of Aircraft Pollution

– By Phil Chadwick –

The title of this 2012 painting below, numbered 1260 in my artistic journey, is “Three Degrees”. That title might sound cryptic. Let me explain.

All air traffic was grounded over North America for three or four days after the terror attacks of 9/11 on September 11th, 2001. A couple of curious meteorologists investigated the impact of grounding those aircraft. They discovered that the skies were much clearer and that temperatures responded correspondingly.

Modular Ocean Research Infrastructure (MORI): A Flexible, Scalable and Affordable Approach to Ocean-going Research in Canada and Worldwide

– By Dr. Doug Wallace (Scientific Director, MEOPAR) and Doug Bancroft (President and CEO, Canadian Scientific Submersible Facility)–

Research vessels (RVs) remain critical infrastructure for many classes of ocean-related research. Robots and autonomous vehicles are used increasingly for monitoring and some process-oriented research when appropriate sensors are available. However, there are also a growing number of questions related to ocean and seafloor resources, as well as complex physical, chemical, biological and atmospheric processes critical to climate change and biodiversity, which require that multidisciplinary teams of researchers can access the ocean with highly sophisticated instrumentation, from vessels.
