I created some gradients to be compatible with latest Gimp.
Those who start with Atmospheric attempt to make Common Atmospheric Effects done in 3D programs in GIMP at ease of drawing a Gradient from bottom of image to top.
There are many Basic Gradient possibilities that done for a quick visual reference and easy of use. Their names start with Basic.
There are also a few modifications of original Gimp Gradients like neons in new colors, and a few unclassified new gradients that neither fit in atmospheric nor basic.
These can either be included with Inkscape distribution package or IS extras...
Ps. sorry for long link. Wiki does not support zip uploads.

Most gradients are now available in SVG format. This is a special Inkscape file It includes hundreds of gradients. They can be accessed and used under gradient dialog of Fill and Stroke menu. You will see the available gradients under Fill & Stroke.
