Summary: Satellite video showcasing ship tracks in clouds on July 12, 2025, first in true color and then via a cloud droplet effective radius map, revealing the impact of ship emissions on cloud properties.
The video begins with true-color satellite imagery of clouds over the ocean, near the coast of California, on July 12, 2025. Clear linear formations, identified as 'Ship Tracks,' are visible within the cloud deck. The imagery then transitions to a specialized map depicting 'Cloud Droplet Effective Radius,' measured in microns. In this view, the ship tracks stand out with significantly smaller cloud droplet effective radii (indicated by purplish/blue hues) compared to the surrounding natural clouds, illustrating how ship exhaust acts as cloud condensation nuclei, leading to more numerous but smaller cloud droplets.
Playback guide
1. start: 00:00 end: 00:01 label: True Color Imagery of clouds over the ocean with visible linear ship tracks and date 'July 12, 2025'. 2. start: 00:01 end: 00:04 label: Text 'Ship Tracks' and an arrow appear, pointing to the linear features in the true color cloud imagery. 3. start: 00:04 end: 00:05 label: The 'True Color Imagery' text fades, and the visual transitions from true color to a color-coded map while 'Ship Tracks' text remains. 4. start: 00:05 end: 00:09 label: Display of 'Cloud Droplet Effective Radius' map with a scale from 5 to 25 microns, showing ship tracks as areas of smaller droplet radii (cooler colors). The date 'July 12, 2025' remains visible.
