In recent products zero values can be observed also sometimes negative values.
CHRIS_G5_200430, but it seems this one has more issue when looking at radiance_2
In the CHRIS format specification, it is said:
“PPU reset errors have been set to zero (originally resulted in negative values in previous releases of the data.)”
Do these values need special consideration?
Red masked values on the left mark negative values and on the right zero values (CHRIS_G5_200430_6ADB_41).
Here zeros are masked in the radiance_1 band on the left. as comparison radiance_2 is shown on the right (CHRIS_U7_201016_731E_41).
