ETM
at Salar de Uyuni

Salar de Uyuni is a slat flat located in the Atacama desert in Bolivia, at an altitude of ~3700 m.
Because depths hardly exceed ~ one meter, the deep water radiances may not be estimated for the visible bands.
This is not too much of a problem though, as the Lw term is mostly important at depth over dark bottoms,
and cloud shadows allow for a rough estimate of atmospheric path radiance.

ALI and HYPERION
at Salar de Coipasa

Salar de Coipasa is a slat flat located in the Atacama desert in Bolivia, at an altitude of ~3700 m.
It provides the opportunity to investigate the linearity of the linearized simplified radiative transfer
at extremely shallow depths over a uniform and very bright bottom, just like Tarawa atoll.

Because depths hardly exceed ~ one meter, the deep water radiances may not be estimated for the visible bands.
This is not too much of a problem though, as the Lw term is mostly important at depth over dark bottoms;
non vegetated desert land and cloud shadows allow for a fairly good estimate of atmospheric path radiance.
