How much snow is on the ground where you are? Cryosphere researchers at the University of Waterloo want to know! The Snowtweets Project provides a way for people interested in snow measurements to quickly broadcast their own snow depth measurements to the web. These data are then picked up by our database and mapped in near real time. We are especially interested in using web-based digital technologies to map snow data; currently, the project uses the micro-blogging site Twitter as its data broadcasting scheme. To view the snow depth measurements (or Tweets), we have developed a data visualization tool called Snowbird that lets you explore the reported snow depths around the globe. The viewer shows where the reports are located and how much snow there is at each reported site. The Snowtweets Project is in early stages of development and we plan to update and improve it as we go along. We rely on user participation to measure snow depth (including zero snow depth) and then send the measurements in.
