British Columbia Ministry of Environment WRF Dataset

Exponent has produced a three-dimensional gridded data base for the British Columbia (B.C.) Ministry of Environment (MoE) using the Weather Research and Forecasting (WRF) model at 4-km grid size.

Data is available for purchase for 2011, 2012, 2013, 2014, and 2015.

The 4-km B.C. MoE WRF dataset covers all of British Columbia (with a 100 km buffer zone along the B.C. border), nearly all of Alberta, a southern portion of the Yukon and Northwest Territories, and a large portion of the northwestern Pacific Ocean. Additionally, the domain covers portions of Alaska, Washington, Idaho, and Montana in the United States.

A map of the B.C. MoE WRF domain is shown below:
