- Observation images of the tropical regions acquired with SGLI
Image of global vegetation index (NDVI)
The image is a map of global normalized difference vegetation index (NDVI) derived from SGLI observation data acquired during January 1st to 9th 2018. NDVI becomes high at active vegetation with high density, indicating the spatial distribution of vegetation on the global scale.
Color Composite Image of Tropical regions
The images are false color composite images* of 250 m spatial resolution captured over South America with SGLI onboard the SHIKISAI around 13:51 on January 5th 2018 (UTC). Vegetations are seen in bright green colors.
- *: Reflectances of SGLI VN8, VN11, VN3 channels are assigned to red, green, and blue colors
Changes in the tropical rain forest in Amazon
Left is a false color composite image* of 250m resolution acquired over Amazon River with SGLI on Jan. 5, 2018. Right is a false color composite image of 250m resolution acquired over the same location with GLI on May 22, 2003. Forested areas are seen in light green whereas non-forested bare lands are seen in reddish brown in the images. During the fifteen years from 2003 to 2018 forests in large areas have been lost.
- *: Reflectances of SGLI SW3, VN11, VN8 channels are assigned to red, green, and blue colors
Color Composite Image of Tropical regions (Central and South America)
The images are false color composite images* of 250 m spatial resolution captured over Central and South America with SGLI onboard the SHIKISAI around 15:44 on January 8th 2018 (UTC). Vegetations are seen in bright green colors.
- *: Reflectances of SGLI VN8, VN11, VN3 channels are assigned to red, green, and blue colors
Color Composite Image of Tropical regions (Africa)
The images are false color composite images* of 250 m spatial resolution captured over Africa with SGLI onboard the SHIKISAI around 9:28 on January 7th 2018 (UTC). Vegetations are seen in bright green colors.
- *: Reflectances of SGLI VN8, VN11, VN3 channels are assigned to red, green, and blue colors
Color Composite Image of Tropical regions (Indonesia)
The images are false color composite images* of 250 m spatial resolution captured over Indonesia with SGLI onboard the SHIKISAI around 1:37 on January 6th 2018 (UTC). Vegetations are seen in bright green colors.
- *: Reflectances of SGLI VN8, VN11, VN3 channels are assigned to red, green, and blue colors
We will continue the initial functional verification (for about three months after launch,) then confirm data accuracy by comparing it with observation data acquired on land, and perform initial calibration and inspection operations including data correction.
