NOTE: THE 10Be/26Al EXPOSURE AGE AND EROSION RATE CALCULATORS WERE UPDATED TO VERSION 2.2 ON MARCH 19, 2009. UPDATE YOUR BOOKMARKS ACCORDINGLY.

Current stable versions: These are complete, in the process of being reviewed, and, once reviewed, will be stable with the exception of minor bug fixes. Use these unless you have a particular reason to use the developmental or archived versions.

10Be - 26Al measurements - Version 2.2:

Calculate exposure ages
Calculate surface erosion rates
Calculate topographic shielding
Instructions and documentation

Developmental versions: These versions are in active development, are very likely to contain errors, may not work at all, and may be offline for changes at any time. On the other hand, they have more features than the stable versions. They appear on a separate page.

Archived versions: These have been superseded by the current stable version, but they are archived here so that calculations done in the past can be reproduced. They appear on a separate page.
