Hurricane images are from the Defense Meteorological Satellite Program (DMSP) Operational Lines can System (OLS). DMSP operates day/night and dusk/dawn satellites. Daytime images are taken with sunlight striking perpendicular to the storm while dusk/dawn images have sunlight glancing across the top of the storm. Images from F12 and F14 are daytime images; those from the F13 satellite are dawn/dusk. Each hurricane is shown in two separate images showing views in the OLS visible near-infrared band and the OLS thermal-infrared band. The spatial resolution of the imagery used is 2.7 km. The thermal infrared images show the temperatures of the cloud tops, and ocean and land surfaces, while the visible-near infrared images show reflected sunlight during the day and reflected moonlight or man-made lights during the night. |
