Yes. I can do that.
The interaction between climate change and ozone is a complex story. Many of the players, in addition to reacting chemically with ozone, are also greenhouse gases themselves. There are two parallel stories going on. An active area of research is just to try to tease that out: the role of ozone on climate change and the impact of climate change on stratospheric ozone. This involves observations, models, and many process studies that isolate a particular process of interest. That's a major challenge that lies ahead in the ozone-climate change story.
Another scientific advance is the use of satellites. Satellites can give us good spatial coverage. There is usually a trade-off between spatial coverage and time coverage when we talk about satellites. Also, satellites need calibration to make sure that what they are measuring is indeed ground truth. That's where the Brewers and ozone-sondes come in as well. The potential added coverage of satellites offers a new and exciting possibility in monitoring ozone.
The third and final aspect I will mention is the incorporation of ozone data into our weather prediction and air quality models. In technical language, we refer to this as “assimilation of data”. These observations have to be brought into, or assimilated into, the models to make sure the models don't run off, and to make sure the models behave properly and are properly constrained. This is a whole area of research. Right now, the Canadian weather and air quality models do not assimilate ozone data directly. One of the major moves we plan to make—one of the major scientific advances—is to actually assimilate or incorporate the ozone data into the model and to make them a happy duo.
