Reconstruction of atmospheric H2 from Greenland and Antarctic firn air

This data set contains:

firn air depth profiles of H2 from 4 polar sites (South Pole and Megadunes in Antarctica) and NEEM and Summit in Greenland used to by Patterson et al., in press to reconstruct the history of atmospheric H2

Matlab code for the UCI firn air model and data used in the reconstructions
