hello, i’m new to the study of remote sensing sensors, i would like to know if there is a blue band in the SLSTR sensor, Sentinel-3. From what I could see, in the visible, there is only the green and red band. Grateful
Yes data is not acquired in the blue band , since SLSTR acquires data in the visible region between (555 and 868 nm), and this means only green, red and NIR bands.
SLSTR mainly provides land and sea surface temperature products.
Depending on your application, you can also use other sensors, such as Sentinel-3 OLCI that capture data in the blue band.
