Radiative Kernel Technique for Calculating Physical Feedbacks in Climate Models

Download the CAM radiative kernels here. The GFDL kernels are available from Brian Soden's website. These kernels are described in the Soden et al. paper below. Please let me know if you use the kernels, so I can include usage information in my grant reports.

Note: The unit in the albedo file is wrong. It should be w/m^2/(0.01 increase in fractional albedo). That is, the kernel corresponds to an increase of 0.01 in the albedo (though it maxes out a 1).

For water vapor, the units are the change in ln(specific humidity) that corresponds to an increase of 1K at that grid point. You need to calculate, for your model, what this change is.
