Daily global maps, created with images from NASA’s Mars Global Surveyor spacecraft, provide a moving picture of Martian weather during 1999-2000 similar to the familiar satellite weather maps we see of Earth. The Martian weather maps will be presented today at the American Geophysical Union meeting in Boston by Dr. Andrew Ingersoll, professor of planetary science at the California Institute of Technology, Pasadena, and an interdisciplinary scientist with Mars Global Surveyor and member of the imaging team.
