climlab.solar.orbital.OrbitalTable is an
holding orbital data (eccentricity, obliquity, and longitude of perihelion)
for the past 5 Myears. The data are from [Berger_1991].
Data are read from the file
orbit91, which was originally obtained from
If the file isn’t found locally, the module will attempt to read it remotely
from the above URL.
works with La2004 orbital data for
-51 to +21 Myears as calculated by [Laskar_2004].
(Breaking change from climlab 0.7.0 and previous)
Load orbital data from the past 5 Myears:# Load the data from climlab.solar.orbital import OrbitalTable # Examine the xarray object print(OrbitalTable) # Get a timeseries of obliquity print(OrbitalTable.obliquity) # Get the orbital data for a specific year, 10 kyear before present: print(OrbitalTable.interp(kyear=-10)) # Get the long orbital table data from climlab.solar.orbital.long import OrbitalTable as LongTable print(LongTable)
