The GEOS-Chem NRT simulations are available from Jan 2008 until present.

Please send bugs/comments to jaegle@atmos.washington.edu. Note that this site does not work with IE, please use another browser (Firefox, Netscape, Safari, etc...).

GEOS-Chem Near-real-time simulation browser: You can view output from the daily near-real-time simulations which are generated with the GEOS-Chem model. Click on "Start NRT browser". A separate control window will appear. You can choose the date, hour, tracer, level that you want to plot. Then click on "PLOT" to see maps of mixing ratios (CO, NOx,O3, HNO3, PAN, acetone, sulfate, dust, sea-salt), columns (CO, NO2, HCHO, O3), or concentrations (OH, NO2, NO). 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 flight track.
