NASA Explores Cloud Testing to Enhance Satellite Data Accuracy

Quick Summary

• In February, NASA’s ER-2 science aircraft conducted flights to improve satellite data products and Earth science observations.
• The flights were part of the Goddard Space Flight Center Lidar Observation and Validation Experiment (GLOVE),which validated satellite data on clouds and airborne particles.
• Instruments installed onboard the ER-2 measured cloud-related data to enhance accuracy in satellite-generated datasets.
• Data from GLOVE is set to test new artificial intelligence algorithms aimed at improving cloud and aerosol detection in space-based sensors.
• The validation process provides higher-resolution measurements to ensure satellite data accurately represents atmospheric conditions.
• Flights were conducted over regions like Oregon, Arizona, Utah, Nevada, and areas off California’s Pacific coast showcasing diverse atmospheres such as cirrus clouds and marine stratocumulus.
• Four specialized instruments aboard the ER-2 supported validation for NASA satellites ICESat-2 and ESA/JAXA’s EarthCARE mission: Cloud Physics Lidar, Roscoe Lidar, Moderate Resolution Imaging Spectroradiometer Airborne Simulator, and Cloud radar System.
• EarthCARE includes a unique Doppler radar that measures air motions within clouds-a first of its kind observation device in space missions.
