The above image is visualized output data from
MOZART, showing the
mixing ratio in parts per trillion of HOX. It is a snapshot in time
looking down over the North Pole at the ~10 millibar level. What is
most interesting about this output is that it shows that MOZART is a
true diurnal model. In the image, the area of the globe where it is
midnight Greenwich Mean Time (along the longitude line running from the
center of the circle to the 0 degree point at the bottom of the circumference)
evidences low levels of HOX. Moving up and counterclockwise, the 90
degree point represents sunrise, when HOX levels begin to increase.
At noon (180 degrees) HOX levels are highest, and decrease
again toward sunset (270 degrees).
