Reconstruction of atmospheric H2 from Greenland and Antarctic firn air

<p>This data set contains:</p> <ol> <li>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 </li> <li>Matlab code for the UCI firn air model and data used in the reconstructions   </li> </ol> <p>Reference:  Patterson, J.
