About this app
This application is for a citizen science project being developed at the University of Colorado at Boulder. It is sponsored by NASA and NCAR. The project requires you to coordinate with the project team to attend our upcoming events where you will be assigned a location to be at a specific time. During the event, you will have oriented your phone and placed it upside down so that it can take pictures every 30 seconds until the event is over. The team will then take these images to learn more about cloud formation.
