Converting CAM Fields to CCPP Standard Names - ESCOMP/atmospheric_physics GitHub Wiki

The tables below attempt to document existing CAM fields and give the equivalent CCPP Standard Name. Type names (e.g., state, ptend) are included to make identification easier. pbuf fields only include the pbuf name.
