So a satellite
like PACE doesn't take photos.
It takes images.
So with satellite imagery,
you can have what we call
true color images
that are similar to what you can see
in reality with your own eyes.
They are using three
colors: red, green and blue to
show an image that looks natural.
Then
we have what we call
false color images
that are more like maps
that use data, and we put colors on them
to make it easier to
see the differences
between the different things
that we want to show in the image.
When I get a PACE file,
at the beginning, it's just data.
So I have to process it
to remove the effects of the atmosphere
and get the color that we see
at the surface.
I have to enhance the colors
to bring out the parts
that are very bright,
like clouds
and the parts that are very dark,
like the ocean,
especially in the dark parts,
there are things
that are really colorful
that don't come out if you
have just a raw image.
the different types
of plankton
actually have different colors
in the wild.
Well, if you grow them in cultures,
you will see, for example,
in the cook, orcas will be pink.
when we make a map of this
and cook orcas
in the ocean,
we were presented
as a pink similar to the real color
as even though the color actually in
the image is not that bright.
