satpy.composites.agri module

Composite classes for the AGRI instrument.

class satpy.composites.agri.SimulatedRed(name, fractions=(1.0, 0.13, 0.87), **kwargs)[source]

Bases: GenericCompositor

A single-band dataset resembling a Red (0.64 µm) band.

This compositor creates a single band product by combining two other bands by preset amounts. The general formula with dependencies (d) and fractions (f) is:

result = (f1 * d1 - f2 * d2) / f3

See the fractions keyword argument for more information. The default setup is to use:

  • f1 = 1.0

  • f2 = 0.13

  • f3 = 0.87

Initialize fractions for input channels.

  • name (str) – Name of this composite

  • fractions (iterable) – Fractions of each input band to include in the result.
