"The online erosion rate calculator formerly known as the CRONUS-Earth online erosion rate calculator:"

The same look, feel and performance you've come to rely on...with exciting new features and terrible documentation!

For calculating the surface erosion rate, given that the erosion rate has been constant long enough for the surface nuclide concentration to reach production-decay-erosion equilibrium.

Version 3 input form.

This is the version 3 data entry form. Should also accept version 2 input.

Information about the version 3 input format: Link

Note that the version 3 input format is the same for exposure age and erosion rate. That is, you have to enter a dummy value for the erosion rate, which is ignored. Version 2 has different input formats for age and erosion.

This code is expected to be stable for exposure-age calculations for He-3 in pyroxene and olivine and Be-10, C-14, Ne-21, and Al-26 in quartz. Although it is also functional for He-3 in quartz, this pair is still under development and may change without warning.

If you encounter an error or a failure, please email me the data that you entered and a description of the problem. Thanks.
