Types of noise remaining after the radiometric correction (a): A set of stripe noise in a PRISM image observed near the Kasumigaura Bridge, 　　　Ibaraki, Japan, on December 28, 2006. (b): A line of missing data in an ASTER TIR image near Gunma and Nagano prefectures, 　　　Japan, on March, 9, 2005. (c): Smear and blooming in an ASTER VNIR image near Futtsu, Chiba, Japan, 　　　on December 8, 2005.

Crosstalk mechanism and its correction

Surface radiance rate as a function of wavelength, 　　　　　calculated for desert, vegetation, and ocean at the surface temperature of 300K under the mid-latitude summer atmospheric model using the radiative transfer code, MODTRAN 5.2.

Clear Confidence Level (CCL) Q values obtained by CAI imager aboard the GOSAT over western Pacific Ocean in middle latitude (Nov. 5, 2009). Red and blue pixels denote cloudy and clear, respectively.

CloudSat radar reflectivity (top), CALIPSO Lidar backscatter (middle), and Cloud screening result obtained by combining radar and Lidar signals (bottom). Vertical and horizontal axes are altitude (km) and longitude (degrees), respectively. Data were acquired over the North Pacific Ocean on Oct. 8, 2006.
