The ARCTAS mission is now over. The GEOS-5 forecasts will continue to be produced for a little while longer, but will end soon. The Harvard GEOS-Chem NRT simulation will continue to be produced.

GEOS-5 forecast browser:
Choose a date on the dropdown menu in the table above and then click on
"Start forecast browser". The dates are indicated in GMT time. There
are two forecasts each day: a 00 GMT forecast and a 12 GMT forecast.
The forecast browser will allow you to view the forecast you selected.
Simply press the "PLOT" button to see maps of the various tracers
calculated with the GEOS-5 chemical forecasts (CO, aerosols,
tagged tracers, meteorological fields). You can then adjust the day,
hour, tracer, latitude, longitude, altitude and plot the results again.
You also have the options of generating an animation or a postscript
file. The curtain display option together with the 'Curtain Plot'
plot type allows you to sample the forecast fields along a proposed flight track.
If you select a vertical level instead of 'Curtain Plot' and select the curtain plot
option, the program will display the flight track on a map. You also have the option of
displaying satellite ground tracks for the day/time selected.
GEOS-Chem Near-real-time simulation browser: Here you
can view output from the daily near-real-time simulations which are
generated with the GEOS-Chem model. You can choose to plot mixing
ratios (CO, NOx,O3, HNO3, PAN, acetone, sulfate, dust, sea-salt),
columns (CO, NO2, HCHO, O3), or concentrations (OH, NO2, NO). You have
the same plotting options as for the GEOS-5 forecast browser.
