Introduction

Start at version x.y.z of MAPL ExtData will support vertical regridding of inputs in very specific cases. The details of this will be described in detail in this wiki page. Note that I will make several references to the CF conventions. Here are the relevant links:

Supported Use Cases

The first implementation supports regridding from one set of GEOS hybrid sigma levels (as defined in the input files) to another set of hybrid sigma levels (as defined by the model).

In addition this is only supported for quantities in the following units mol mol-1, kg kg-1, and kg m-2. In addition all these can be be per second, I.E. kg m-2 s-1 or mol mol-1 s-1. Note that the input files and the units in the GEOS fields being delivered to ExtData must agree.
