inso 1.2.0

A module to compute insolation based on eccentricity, obliquity, and climatic precession parameters from various astronomical solutions (Berger 1978, Laskar 2004, ...).

Insolation

This software consists of three Python libraries:

• astro.py: an interface (or computational module) providing various astronomical solutions (Berger 1978, Laskar 2004, ...) to deliver parameters needed for insolation: eccentricity, obliquity, and climatic precession. The reference solution is Laskar 2004.
• inso.py (depends on astro.py): computes different types of insolation—instantaneous, daily averaged, or other averaged insolation—as well as "caloric seasons", useful for paleoclimatic and long-term climate studies.
• minmax.py (depends on astro.py and inso.py): computes extremal values of daily insolation.

Some usage examples are also provided. In particular, figures.py generates several figures from the paper by Paillard (2026), On the computation of several “insolation” quantities relevant to climatology or planetology, published in Climate of the Past, 22, 647–673. https://doi.org/10.5194/cp-22-647-2026
