Abstract:

Soil
Moisture
and
Ocean
Salinity
(SMOS)
brightness
temperature
synthesized
images
are
obtained
after
a
comprehensive
calibration
and
error
correction
procedure.
However,
the
final
images
are
still
contaminated
by
small
but
non-negligible
spatial
errors:
the
so-called
pixel
bias.
These
errors
have
been
found
to
be
very
stable
in
the
SMOS
Alias-Free
Field
of
View
(AF-FoV)
and
can
be
mitigated,
to
a
large
extent,
by
applying
a
multiplicative
mask
to
the
measured
brightness
temperatures
at
the
antenna
plane.
This
paper
describes
the
procedure
to
upgrade
this
mask
to
cover
SMOS
Extended
AF
FoV. |
