This is work in progress, and new links to the exercises will be inserted below.
 
 

Ozone and UV radiation	Impact of the ozone layer on UV radiation at various levels in the atmosphere. You can change the total amount of ozone and see the resulting effect on the penetration of UV radiation in the atmosphere.
Stratospheric Ozone and the Chapman Mechanism	Calculation of the ozone profile in the stratosphere based on the 4 reactions from the Chapman mechanism. You can change the latitude and season of the calculation, and plot the reaction rates.
Global distribution of tropospheric OH concentrations	Display global concentrations of hydroxyl radical (OH) concentrations. The concentrations are calculated with a global three-dimensional model of tropospheric chemistry, GEOS-CHEM. These concentrations are averaged over one month.
Global distribution of tropospheric O3 and its precursors	Display global concentrations of tropospheric O3 concentrations and of its precursors (CO, NOx, and related species). The monthly averaged concentrations are calculated with a global three-dimensional model of tropospheric chemistry, GEOS-CHEM.

About this page:
These exercises were developed with funding from a NASA New Investigator Program in Earth Science grant. The web pages were written using ION Script (IDL On the Net), which allows to publish interactive IDL applications over a networked environment.  ION can call a set of IDL subroutines to generate the graphics based on user inputs, and it can also call fortran programs.  The exercises are run on a dedicated web server running Linux (733 MHz Pentium III and 256 MB of memory).
