We are currently experiencing some techincal difficulties with our web page scripts, and have therefore resorted to a temporary fix of the situation. This fix is not elegant, but it will allow users to regain access to our images and data from our tropical tropospheric ozone data sets. Below is instructions about how to obtain data and images for the satellite you have chosen. Please understand that our archived image and data sets have some gaps, so you may not be able to access images for particular time periods. However please feel free to contact the webmaster/ data manager with any questions regarding the location of data and images (email: jstone@atmos.umd.edu).

Please type the following pathname directly into your browser's location bar:

for half month images:

http://atmos.umd.edu/~tropo/14y.d/best_tto_yymm.gif

for half month data (given as 1 file per year)

http://atmos.umd.edu/~tropo/14y.d/best_tropoz_yy.dat

Where 'yy' stands for a two digit year (from '79' through '92') and 'mm' stands for a two digit month (from '01' through '12').

Again, we apologize for the less-user friendly method of data and image selection, but we hope the problems with our current web pages will be soon fixed and we'll have a more user friendly page for accessing the data archives once again. Thanks for your patience.
