In this page some studies on Montreal hourly solar direct beam radiation models between 1953 and 2005 are presented. The data is normalized by SOLARCHVISION internal algorithm using the solar components available in CWEEDS files provided by National Climate Data and Information Archive of Environment Canada available at: http://climate.weather.gc.ca/prods_servs/engineering_e.html
