CoCoRaHS is a community-based weather network of volunteers across the nation who report precipitation totals every morning. These precipitation measurements are extremely helpful for a variety of fields and are shared daily on the CoCoRaHS website for all to view. 

Want to become a CoCoRaHS volunteer observer? It's free! Just go to cocorahs.org to apply. All ages are welcome and training is provided online. You can use your rain gauge if you already have one that follows their requirements, but will need to purchase one if it doesn't.  The program will provide you with a free rain gauge if you commit to reporting daily.  They also provide a link to purchase an approved rain gauge on their website
