s3-(OLCI) cr2cc processor retrieves one of the IOPs(gelbstoff absorption coeff. at 443 nm, units /m). My question is that, why not gelbstoff absorption coeff. at 400/412 nm have been chosen as standard product of s3-olci instead of 443nm (since gelbstoff absorption is stronger towards blue/uv). Is there any technical /scientific reason for that?
Another question is that when I processed (using CR2CC) and generated rhown in coastal waters of India I observed that rhown is varying at only third and fourth decimal places (first and second decimal place remain constant in rhown) while going from coast to open ocean for say more than 100/150 pixels? Is it possible that coastal and open ocean water rhown value remain same & do not vary upto first or second decimal place. Please correct/guide me if I am processing wrong somewhere.
