sen2nbar.nbar¶

Core module of sen2nbar. Computes NBAR:

`nbar_SAFE`(path[, cog, to_int, quiet])	Computes the Nadir BRDF Adjusted Reflectance (NBAR) using the SAFE path.
`nbar_stac`(da, stac, collection, epsg[, quiet])	Computes the Nadir BRDF Adjusted Reflectance (NBAR) for a `xarray.DataArray`.
`nbar_stackstac`(da, stac, collection[, quiet])	Computes the Nadir BRDF Adjusted Reflectance (NBAR) for a `xarray.DataArray` obtained via `stackstac`.
`nbar_cubo`(da[, quiet])	Computes the Nadir BRDF Adjusted Reflectance (NBAR) for a `xarray.DataArray` obtained via `cubo`.

Extracts information from Sentinel-2 metadata:

`angles_from_metadata`(metadata)	Gets the angle values per band (and Sun) in Sentinel-2 granule metadata.
`get_processing_baseline`(metadata)	Gets the processing baseline in Sentinel-2 user metadata.

Computes the required kernels for BRDF:

`kgeo`(sun_zenith, view_zenith, relative_azimuth)	Computes the Geometric Kernel (Kgeo).
`kvol`(sun_zenith, view_zenith, relative_azimuth)	Computes the Volumetric Kernel (Kvol).

Computes the BRDF:

brdf(sun_zenith, view_zenith, relative_azimuth)

Computes the Ross-Thick/Li-Sparse Reciprocal Bidirectional Reflectance Distribution Function (BRDF) Model.

Computes the c-factor:

`c_factor`(sun_zenith, view_zenith, ...)	Computes the c-factor.
`c_factor_from_metadata`(metadata)	Gets the c-factor per band from Sentinel-2 granule metadata.
`c_factor_from_item`(item, to_epsg)	Gets the c-factor per band from a Sentinel-2 `pystac.Item`.
