Landsat-8 Processing Parameters

Valid-pixel expression
The arithmetic expression defines the pixels which are valid for processing. Pixels which are not valid will be marked as no-data in the target product. For Landsat 8 no default expression is provided. There are multiple way of doing defining an expression. Usually one would want to discriminate between land and water. The expression depends on how the landsat reader is configured.
By default the values are radiances.
near_infrared > 0 && near_infrared < 25
If you have switched to reflectances, the following should work.
near_infrared > 0 && near_infrared < 0.1
The exact values might need to be adjusted.
Alternatively, Idepix can be used for preprocessing and adding a land/water mask, or an elevation band can be added and based on the elevation value land and water can be discriminated. Or the land-sea mask operator can be used.
Salinity
The value used as water salinity for the scene.
Temperature
The value used as water temperature for the scene.
Ozone
The value used as ozone if not provided by auxiliary data.
Air Pressure
The surface air pressure at sea level if not provided by auxiliary data.
Elevation
The value used as elevation for scene.
TSM factor bpart
Conversion factor bpart. (TSM = bpart * TSMfakBpart + bwit * TSMfakBwit)
TSM factor bwit
Conversion factor bwit. (TSM = bpart * TSMfakBpart + bwit * TSMfakBwit)
CHL exponent
Chlorophyll exponent (CHL = iop-apig^CHLexp * CHLfak)
CHL factor
Chlorophyll factor (CHL = iop-apig^CHLexp * CHLfak)
Threshold rtosa OOS
Threshold for out of scope of nn training dataset flag for gas corrected top-of-atmosphere reflectances.
Threshold AC reflectances OOS
Threshold for out of scope of nn training dataset flag for atmospherically corrected reflectances.
Threshold for cloud flag on down transmittance @865
Threshold for cloud test based on downwelling transmittance @865.
Atmospheric aux data path
Path to the atmospheric auxiliary data directory. Use either this or the specified products on the I/O Parameters (ozone, air pressure) tab. If the auxiliary data is not available at this path, the data will automatically be downloaded. More information about the auxiliary data and its handling is provided on the Auxiliary Data Directory page.
Alternative NN Path
Path to an alternative set of neuronal nets. Use this to replace the standard set of neuronal nets. This is a parameter which should only used during the development of new neural nets.
Set of neuronal nets
Set of neuronal nets for the algorithm. Selectable is either C2RCC_Nets or C2X_Nets.
Output AC reflectances as rrs instead of rhow
Write remote sensing reflectances instead of water leaving reflectances.
Derive water reflectance from path radiance and transmittance
Alternative way of calculating water reflectance. Still experimental.
