Welcome to the GEOS-Chem High Performance (GCHP) Working Group wiki page! GCHP represents the next generation of GEOS-Chem with a distributed memory capability enabling efficient scaling across many cores and finer resolution simulations. GCHP also has the advantage of using a cubed-sphere geometry enabling more accurate transport and eliminating the polar singularity inherent to lat-lon grids.

If you are interested in working with or contributing to GCHP development, please subscribe to the GCHP Working Group email list following the instructions below and send an email introducing yourself. We also encourage you to your platform and operation system as well as a description of your project in the tables on this page.
