The Atmospheric Correction Parameter Calculator has been moved to a new server and web host. I have tested as much as I can, but please let me know if you run into problems.
If you are using a script, the path has changed. Click here for more details.
Please do not submit queries more often than every 2 minutes. Repeated rapid querying of the site causes problems for all users. Thanks for your cooperation.
Please email me if you have issues with this.
