Hi,
My personal opinions (not those of NSIDC):

there is some merit to adding "water" in describing the melt ponds you
detect radiometrically from above, as there are also refrozen melt
ponds, and you can even have liquid water below a snow-covered ice layer
covering melt ponds.
But melt pond (you will also see meltpond as one word in the literature)
is widely used to refer to puddled, unfrozen water on sea ice surfaces.
> "melt pond area fraction": area(melt ponds)/(area(melt ponds)+area(ocean water)+area(sea ice)).
The above would agree with the statistics from one of the most
widely-cited inventories of melt ponds
(
http://nsidc.org/data/docs/noaa/g02159_ponds/) IF area(sea ice)
EXCLUDES (area(meltponds)
> "melt_pond_at_top_of_sea_ice_area_fraction"?
I find this term confusing
> "melt pond free sea ice area fraction": area(sea ice)/(area(melt ponds)+area(ocean water)+area(sea ice)). "melt_pond_free_sea_ice_area_fraction"?
area(sea ice) excludes sea ice with melt ponds?
> I would need these names for better defining upcoming satellite products of ice concentration and melt pond area fraction.
