Coverage
AIRS coverage is pole-to-pole, and covers the globe two times a day. Because the swaths (scanning sweeps) do not overlap at low latitudes, some points near the equator are missed. However, these points are eventually scanned within 2-3 days.

438 miles (705.3km) polar, sun synchronous, 98.2+/- .1 degrees inclination, ascending node 1:30pm +/- 15 minutes, period 98.8 minutes
Ground Footprint
90 per scan, 22.4 ms footprint
Swath Width
1650 km
Ground Coverage
+/- 49.5 degrees around nadir
Temporal Coverage
global, twice daily swath (daytime and nighttime)
