Global SWIR Albedo Mapo Fraction of incident solar
radiation reflected by the surface.
o Wavelength band 1.64-1.66 µm
o Spatial resolution ~50 km
o Low value – Dark surface (having volcanic rock basalt)
o High Value – Covered with Dust.

Polar Ice Capo Ls=0º is the start of
northern springo Ls=180º is the start of
southern spring.
o Northern winters (Ls=270-360º) - cap grows much larger.
o Summer returns (Ls=90-180º) - - Polar cap shrinks in size.
o Ice and Dust - “Polar Layered Terrain"

It’s time to come back to Earth.Hope you have enjoyed the journey with MOM.
Thanks.
