Ontario Climate Data Portal




Maps:

Thousands visually-appealing, informative and interactive web maps based on a big ensemble of climate projection dataset.

Figures

Annual variations of basic climate variables and climate extreme indices tell us how fast the climate is changing at various spatial levels.


Data

Large ensembles of high resolution historical observations and future projected climate data for climate change and impact researches.

Documents

Many PDF formate reports or web pages about special climate change topics including factsheets, present and future climate condition analyses.


FAQ

Answers of some questions about all aspects related to the OCDP including data sources, methodology, products and our future researches.

About

Brief introduction of the climate change group at LAMPS, York University and the works we did and will do in the future.
