NASA has announced an extension for its ongoing citizen science initiative, which invites members of the public to submit photographs of clouds. The project is designed to gather ground-level observations that complement data collected by orbiting satellites. By comparing these user-submitted photos with satellite imagery, researchers aim to improve the accuracy of cloud monitoring and atmospheric analysis.

The agency is encouraging participants to capture images of various cloud formations and sky conditions. These submissions serve as a vital ground-truth verification for satellite sensors, which can sometimes struggle to distinguish between different types of cloud cover or surface features. NASA has not specified a new final deadline, but the extension suggests a continued need for a larger volume of data to ensure the project's scientific objectives are met. Participation is open to anyone with a camera and an interest in atmospheric science, with the agency providing guidelines on how to best document sky conditions for research purposes.
