satpy.composites.abi module

Composite classes for the ABI instrument.

class satpy.composites.abi.SimulatedGreen(name, fractions=(0.465, 0.465, 0.07), **kwargs)[source]

Bases: GenericCompositor

A single-band dataset resembling a Green (0.55 µm) band.

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

result = d1 * f1 + d2 * f2 + d3 * f3

See the fractions keyword argument for more information. Common used fractions for ABI data with C01, C02, and C03 inputs include:

  • SatPy default (historical): (0.465, 0.465, 0.07)

  • CIMSS (Kaba): (0.45, 0.45, 0.10)

  • EDC: (0.45706946, 0.48358168, 0.06038137)

Initialize fractions for input channels.

Parameters:

  • name (str) – Name of this composite

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