Bands 2,7,8,9,10, and 13

Question 1

Band 2

Answer 1

.64 um, .5 km resolution
Red Visible band
ideal for small scaled features (river fogs, overshooting tops, cumulus clouds)
Primarily used for detection of clouds and weather systems during the day.
Input into RGB imagery, the red is used to create true color

Limitations include, daytime only, and cannot analyze too big of a picture.

Question 2

Band 7

Answer 2

3.9 um 2km resolution
Shortwave IR Band
Primarily identifies fog and low clouds @ night, identify fire spots, volcanic ash, SST’s, and differ b/w ice crystal size during the day

Limitations are that 2km resolutions mean smaller fires can go overlooked, and solar reflectance adds to the detected 3.9 um radiation

Question 3

Band 8

Answer 3

6.2 um 2 km
Upper Level WV Band
1 of 3 WV bands, used for tracking upper tropospheric winds, jet streams, hurricane track, and mid latitude storm motion.

Primarily used for finding jet streams, troughs and ridges, and signatures of potential turbulence
Key component of airmass RGB product

Limitations include dense clouds can obstruct view, and skewed interpretations of WV.

Question 4

Band 9

Answer 4

6.9 um 2 km
Mid Level WV Band
identifies jet streams, vorticity centers, signatures of potential turbulence, and contrails
limitations include presence of dense clouds blocks the view

Question 5

Band 10

Answer 5

7.3 um 2 km
Lower Level WV Band
senses the furthest down in cloud free regions
identifies jet streaks, dry slots, potential turbulence, contrails, downslope winds, and Lake Effects. also helps identify plumes with high concentration of SO2
Limitations include presence of dense clouds obstruct the view

Question 6

Band 13

Answer 6

10.3 um 2 km

Clean Infrared Window
