Secondary information tested is a natural area indicator, which is a combination of topographic features and weather conditions. Cross validation shows that secondary information only marginally improves the final mapping, indicating that a one-day accumulation time is possibly too short. %U http://www.adv-sci-res.net/4/29/2010/asr-4-29-2010.html
