This two-layer graphic shows a yellow and white smiley face atop a land aerosol optical depth image collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra and Aqua satellites. The smiley face is placed on a white background gridded by 144 squares with thin blue lines. The grid is grouped into 16 larger tiles bordered by thicker blue lines. The MODIS image is placed below the smiley face and primarily consists of colors fading from dark blue to aquamarine.

This image shows a temperature map of South Florida and Miami-Dade County using MODIS data. Areas on the right side of the image are in the county and along Florida’s Atlantic coast. These areas are colored in variations of yellow, orange, and red to indicate higher land surface temperatures. The surrounding area is largely colored in shades of green to show lower temperatures. A temperature scale in Celsius is also included showing the range of temperatures from green to red to be from 28.7 to 47.6 deg.
