xrspatial.fire.dnbr(pre_nbr_agg: DataArray, post_nbr_agg: DataArray, name: str = 'dnbr') → DataArray

Differenced Normalized Burn Ratio (dNBR).

Computes pre_nbr - post_nbr. Higher values indicate greater burn severity.

Parameters:

• pre_nbr_agg (xr.DataArray) – Pre-fire NBR values.

• post_nbr_agg (xr.DataArray) – Post-fire NBR values.

• name (str, default='dnbr') – Name of output DataArray.

Returns:

dNBR values (float32).

Return type:

xr.DataArray
