This a square image of a portion of Eastern Texas. The image was taken by the TEMPO spacecraft and shows nitrogen dioxide gas levels across the region. A majority of the image is colored blue indicating lower levels of gas. The upper left corner of the image shows the city of Dallas colored in orange, red, and black indicating increasingly higher levels of gas. In the lower middle of the image is Houston, again colored in orange, red, and black indicating increasingly higher levels of gas.
