TLDR
In this paper, a trigonometrical formula for the Earth's orbital elements is presented, which allows direct spectral analysis and the computation of those long-term variations of the orbital elements which are of primary interest for the calculation of the insolation.Abstract:
Provides all trigonometrical formulas which allow the direct spectral analysis and the computation of those long-term variations of the Earth's orbital elements which are of primary interest for the computation of the insolation. The elements are the eccentricity, the longitude of the perihelion, the precessional parameter and the obliquity. This new formulary is much more simple to use than the ones previously designed and still provides excellent accuracy, mainly because it takes into account the influence of the most important higher order terms in the series expansions. The daily insolation both for calendar and solar dates is computed.read more

Insolation values for the climate of the last 10 million years
André Berger,Marie-France Loutre +1 more
TL;DR: In this article, new values for the astronomical parameters of the Earth's orbit and rotation (eccentricity, obliquity and precession) are proposed for paleoclimatic research related to the Late Miocene, the Pliocene and the Quaternary.

A long-term numerical solution for the insolation quantities of the Earth
Jacques Laskar,Philippe Robutel,F. Joutel,Mickael Gastineau,Alexandre C. M. Correia,Alexandre C. M. Correia,Benjamin Levrard +6 more
TL;DR: In this article, a new solution for the astronomical computation of the insolation quantities on Earth spanning from −250 m to 250 m was presented, where the most regular components of the orbital solution could still be used over a much longer time span, which is why they provided here the solution over 250 m.

A High-Resolution Absolute-Dated Late Pleistocene Monsoon Record from Hulu Cave, China
Yongjin Wang,Yongjin Wang,Hai Cheng,Richard Lawrence Edwards,Zhisheng An,Jiangying Wu,Chuan-Chou Shen,Jeffrey A. Dorale +7 more
TL;DR: The record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates and generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2).
