"EPIC makes images of the sunlit face of the Earth in 10 narrowband spectral channels. As part of EPIC data processing, a full disk true color Earth image will be produced about every two hours. This information will be publicly available through NASA Langley Research Center in Hampton, Virginia, approximately 24 hours after the images are acquired."

Nooooo sad.gif That's what makes images look realistic and not like yet more CGI...

Yes there is good information on aerosols and the like by seeing the true color of the Earth. I wonder if they could make both original and processed imagery available?

Adam Szabo confirmed to me today that they plan to release both original and processed images. Although, to be clear, they're all processed at some level. Not sure about PDS (or PDS-like) release schedule.

Thanks Emily for the update and blog post. It's possible the raw data could be archived in NOAA's CLASS system if it is handled like some of the polar orbiter weather satellite data (e.g. NPP SUOMI).

Nice that we (and the rest of Earth's inhabitants) will then be able to see the realistic color views of Earth, complete with the air we breathe. I suppose we can also experiment with tweaks to the methods of making RGB images. The simulated imagery I linked to in post #44 has some similarities in that the 3 narrowband radiances can be convolved with the solar spectrum, then processed by determining tri-color stimulus values and using an RGB transformation matrix to produce the RGB image.

I like seeing the real (well... closer to "real") colors.

The Caribbean is incredible... the shallows there are almost emerald-colored.

I now understand raw data will be available this fall via the Science Team web server.

We do live on a beautiful world. I expect Aliens will come to visit just for the aesthetics.

This is so very cool! I have been waiting to see this; didn't realize they would capture it so soon.

We live in a very beautiful system!

I wonder what the source of the fringe around the Moon is? Color channel misregistration?

Time lag between different color images--doesn't matter as earth rotates little--bigger problem for moon flying past.

My attempt to correct for the motion of the Moon, in addition to whatever processing caused blue filter signal to leak into the red and green channels:

Wow! I was actually wondering if being at L1 would allow transits to happened regularly. Apparently this is twice a year (plus the Moon being occulted two weeks before/after).

Fascinating... This image does give a layperson such as myself an idea of the brightness/albedo of the moon compared to earth. It is darker than I expected!

Good find on the transit. Neat that we are seeing the far side of the moon. I wonder how the lunar occultation will look in late September, when we are also having a total lunar eclipse? Will we see any of the penumbra (or even umbra) on the moon? This might depend on the fact that DSCOVR varies a bit from being exactly along the Sun - Earth line.
