“GLOBE Observer: Clouds is an app-based tool that will help you document what you see in the sky. Once you have downloaded the app and created an account, the Clouds tool (including the Clouds Wizard if you wish to use it) will guide you through the observation process. Required data includes providing your location, reporting on overall cloud cover and surface conditions that can impact satellite observations. Optional (but very useful) data include cloud types, cloud opacity, sky conditions and visibility, then taking photos of what you see in the sky. Even a basic observation without optional elements is valuable!”
