Environment Canada employs staffed and automated weather stations across Canada to collect temperature, rain and snowfall amounts, wind direction and speed, and barometric pressure. Data may be updated as necessary. It also includes long term weather records used in urban planning and green building design, as well as estimates of hourly solar radiation amounts.
