Useful alternatives are CHLOE, an Excel spreadsheet for cosmogenic ).Cosmo Calc was developed independently from these other tools, except for its topographic shielding correction function, which was translated into VBA from the Matlab code of Balco and Stone (2007).Default parameters are set so that beginning users only have to make a minimal number of decisions.At the same time, all the default parameters can be changed so that Cosmo Calc is highly customizable and also experienced users should find it useful.The oldest and still most widely used scaling model is that of Lal (1991).This model is a simple set of polynomial equations giving the (spallogenic muogenic) production rate relative to SLHL as a function of geographic latitude and elevation.
To apply the TCN method to other field settings, the production rates must be scaled to a common reference at sea level and high latitude (SLHL).
Cosmo Calc is an add-in to MS-Excel developed with the intention to alleviate this problem.
The Cosmo Calc interface was designed to be as user friendly and easy-to-use as possible.
Surface exposure age dating requires intensive chemistry.
Our samples are now pre-treated at the University of Canterbury.

The first applications of Terrestrial Cosmogenic Nuclide (TCN) geochronology appeared about 20 years ago (Kurz, 1986; Nishiizumi et al., 1986; Phillips et al., 1986).
