Weather Stations

The CWFIS currently uses weather data from about 2500 stations in Canada and the United States. About 900 of these stations are operated by Environment and Climate Change Canada (ECCC) or other federal departments under contract to ECCC. About 600 stations are operated by the National Weather Service (NWS) of the United States, and the remainder of the stations are operated by the provincial and territorial governments.

The online data mart managed by ECCC provides a source for many observations from stations operated by federal agencies. Observations from stations belonging to Alberta Agriculture and Forestry’s drought monitoring program also can be downloaded here, and observations from United States locations are usually obtained from Unidata (a university data-sharing program) nodes. Data from provincial and territorial wildland fire management programs are obtained through various methods.
