Summary
Abstract: Data on changes in the earth's orbital parameters and the resulting
variations in insolation were calculated by A. Berger of the Catholic
University of Louvain in Belgium. Data includes both the 1978
calculations and the latest (1991) solution published in Quaternary
Science Reviews. The 1978 solution is preferred for time 0 (1950
A.D.). The two solutions are equivalent through 800,000 YBP, and the
1991 solution is preferred for times greater than 800,000 YBP. The
format of the 1978 files is described in the file
"ftp://ftp.ncdc.noaa.gov/pub/data/paleo/insolation/contents.78". The
format for the 1991 files is in file
"ftp://ftp.ncdc.noaa.gov/pub/data/paleo/insolation/contents.91".
Please cite Dr. Berger when using this data.

A version of this data set Earth Insolation for 1.1 Million Years is available
from NCAR at cost. See: "http://rda.ucar.edu/datasets/ds861.0/"
