WHAT'S NEW Robert L. Park Friday, 6 Jan 06 Washington, DC DEEP SPACE CLIMATE OBSERVATORY KILLED. http://bobpark.physics.umd.edu/index.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

I've recently made some fixes to the handling of Rayleigh scattering in making simulated Earth images. This makes the simulated blue sky (over ocean areas) somewhat darker than previously. As a result less color adjustment to the DSCOVR web images is need to make a match. Hopefully this is now a more realistic color and contrast.
The left is simulated (ray-traced) from global 3-D weather and land surface data, right is a DSCOVR/EPIC image at the same time. In general my simulations come up a little short on the brightest cloud reflectance values. This can be partially addressed by adjusting the anisotropic reflectance factor for the bright cloud tops. -------------------- Steve [ my home page and planetary maps page ]
