1. mPing is a free app for mobile devices that, when it was first launched, was intended to record wintertime precipitation. It has since evolved to include observations of hail and other weather patterns.

2. Pieris Project asks citizen scientists to record information about Pieris rapae, or the white cabbage butterfly. The goal is a comprehensive database about this one insect that may also shed light on wider relationships between organisms and their changing environments.

3. NASA Observer Cloud App allows citizen scientists to work with NASA scientists as they document cloud observations and their changes.

4. CoCoRaHS, or the Community Collaborative Rain, Hall & Snow Network, is an opportunity for communities to measure and map precipitation patterns, including rain, hail, and snow, using low-cost equipment.

5. SmartFin connects surfers and their communities with issues affecting ocean health. The data collected is used to better understand ocean trends and mobilize communities to take action against problems caused by climate change.

6. Cynaobacteria Monitoring Collaborative relies on reports from local communities to identify the timing and occurrence of harmful algae blooms and their impact on water health.

7. Cyclone Center is a project that collects information about tropical cyclones by having participants answer questions online about tropical cyclone imagery.

8. RinkWatch is a digital project that asks everyday citizens to track climate change through backyard skating rinks. Volunteers provide the location of their backyard rink and document the number of days they can skate.

9. Nature’s Notebook engages with the public by asking volunteers to make ongoing observations about the flora and fauna they find in their yards.

10. StreamSelfie is a simple way to get involved with water quality monitoring. Citizen scientists are asked to take a selfie in front of their local streams and share it.
