We need your help classifying snowflakes from all over the world- Utah, Alaska, Colorado, New York, Antarctica, the Swiss Alps, and Korea. When it snows in these places, a special camera takes photos of the falling snowflakes from 3 angles. You can use those photos to tell us what type of snowflake was photographed. We'll take the classification you give us and use it to teach a computer how to classify snowflakes automatically. This is important work because snowflake categorization helps scientists learn more about climate change!

 

Snowflake characteristics such as size, shape, and density are important for accurate forecasting of severe weather and global climate change. For example, the Intergovernmental Panel on Climate Change (IPCC) has stated that accurate representation of the size, shape, and density of snow and ice particles is one of the most important factors for accurately predicting the amount of global warming for a given amount of increased greenhouse gases. Likewise, the exact type of snowflakes falling during a winter storm is directly related to how quickly the snow piles up and affects civilian life.
