Local Mapping Strategy for South Polar Region

• Rev 38 Regmap (range 16 Rs)

– Mid-IR temperature (upper tropospherre and stratosphere) mapping of circumpolar vortex and near south pole

• Rev 30 Regmap (range 12 Rs)

– Composition integration within vortex

• Rev 30 Feature Track (range 5.8 Rs)

– Target south pole & vortex region

– Sub-spacecraft latitude: 43° S

– Nadir-viewing mode only

– Driven by far-IR mapping of temperatures (=15.5 cm-1)

Rev. 38, 8-hour segment: Mid-IR driven, arrays sit, =3 cm-1, blinking mode

Rev. 38, 3-hour segment: Mid-IR driven, arrays sit, =3 cm-1, blinking mode

Rev. 30, 9-hour segment: arrays sit, =0.5 cm-1, paired mode

Rev 30 Feature Track, =15.5 cm-1, map out square size of WAC (3.5° x 3.5° in the sky). Current design @ 45° S; could shift to south polar region; viewing less favorable than later.
