The JRA v1.5 runoff files have negative values for liquid runoff rofl around Greenland and Antarctica. It seems that in post-processing for v1.5, the friver quantity had the solid ice runoff, lcalvf, subtracted twice, resulting in some negative values around Greenland and Antarctica where lcalvf is present.

h/t to @proteanplanet and @cbegeman for finding the issue and it's apparent source.
