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.
