  1. Summary by month of daily mean temperature, total precipitation, and maximum wind gust speed, during 1970 - 2007, from the National Climate Data and Information Archive of Environment Canada http://www.climate.weatheroffice.ec.gc.ca/, recorded at the Vancouver International Airport, located adjacent to the Fraser estuary. The table records for each winter month the overall mean, the slope of the regression on year (1970 to 2007), and the proportion of the variance explained (r2).
