Northern CA PPSR Projects 1

Welcome to our ongoing effort to catalog citizen science and other public participation in scientific research (PPSR) projects for UC California Naturalists and other citizen scientists.  We invite you to browse the listed projects or enter key words (like birds, youth, invasive, coast, Alameda, etc.) in the search box above to find projects in your area. It's a great way to stay involved and keep developing your skills as a natural scientist!

A vast majority of the information in the database was gathered from project websites and may be out of date. We encourage you to contact projects directly to get involved and learn about most recent opportunities. If you work with a listed project and would like to add to, update, or correct the information we have, please email Also, please consider filling out the "PPSR perspectives" survey. Click here to access the survey, which will help guide this project in the coming year.

If you know of a project not on our list, please go to the "tell us about a project" link on the left so we can list the project here. Thanks for your help!

Special thanks goes to the National Science Foundation Informal Science Education program and the Stephen J. Bechtel, Jr. Foundation for supporting this database of projects.

If you are an amateur radio operator sending APRS weather data to findU, you can join APRSWXNET/CWOP with an e-mail to with your callsign, nearby town, zip code, and elevation in meters (not feet).

Project Purpose (taken from project materials)

1) to collect weather data contributed by citizens; 2) to make these data available for weather services and homeland security; and 3) to provide feedback to the data contributors so that they have the tools to check and improve their data quality.

Participant Activities

CWOP members send their weather data by internet alone or internet-wireless combination to the findU server and then every five minutes, the data are sent from the findU server to the NOAA MADIS server. The data undergo quality checking and then are distributed to users.

How will the findings be used?

Real time observations from your home weather station can be of great interest to the many people across the country who share your interest in the weather. These data are also of interest to NOAA and your weather data will be included on the NOAA Mesonet Dataset and distributed to user organizations.
