File names are in the form cAmmddhh.gif, where
A is an altitude code: "1", "8", or "x", for 1, 8, or 10 km.
"mmddhh" gives month, day, and hour.

DC8 flight path has been added to PEMT-B total CO simulation.
This includes industrial/urban emissions, biomass burning,
isoprene and methane contributions. Boundary conditions are
based on MAPS and PEMT-B observations.

The simulations used MM5 and Graces run at 100 km resolution
and were spun up from 20 February.

The flight path is shown for time from 3 hours before the time
of the plot to 3 hour after.

The color of the flight path plot is
green, if the aircraft was within 1 km of the plot altitude.
red, if the aircraft was below the plot altitude - 1 km.
blue, if the aircraft was above the plot altitude + 1 km.

For example, for the 1 km data, green lines indicate all
locations for where the aircraft altitude was between 0 and 2 km,
blue lines indicate that the aircraft was above 2 km.
A red line in not possible for the 1 km data.

Our analysis suggests that transport patterns within a 2 km region
are similar.
