Description
ClimKern Kernel and Data Repository
New in v1.2.1
-
The ECHAM5 kernel, which has known issues, was included here for legacy purposes. However, we have decided to remove it from the repository moving forward to discourage its use by the community.
New in v1.2:
- An error was discovered in the HadGEM2 clear-sky surface albedo kernel. Please use v1.2 or later for that specific kernel.
What's stored here?
This Zenodo repository contains two types of data to be used by the ClimKern
Python package. The subdirectory
/kernels/ contains 11 radiative kernels generously contributed by various research groups. The other directory
/tutorial_data/ contains sample Community Earth System Model v1 output for testing purposes.
