Hi Peppe,
GeoServer 2.8.0 is probably just too old to have a meaningful discuss about
it, I'd first recommend to
upgrade to 2.12.x
Since you have data with NODATA embedded, I would suggest to then enable
JAI_EXT and let it
handle it without fiddling with background colors, input transparent color
and output transparent color
(btw, the last two are colors, they do not make sense if the mosaic is made
of scientific data, at least
as far as I know).
JAI_EXT is not enabled by default, you'll have to set up a system variable
to kick it on:
http://docs.geoserver.org/stable/en/user/configuration/image_processing/index.html#jai-ext
Cheers
Andrea
