Terra-Aqua’s Global Perspective

• MODIS– 1-2 day global coverage in 36

wavelengths from 250 m to 1 km resolution

• MISR– Stereo images at 9 look angles

• ASTER– Hi-resolution, multi-spectral images from

15 m to 90 m resolution, plus stereo

• MOPITT– Global measures of CH4 & CO

• CERES– Measures Earth’s shortwave, longwave,

and net radiant energy budget
