Data and code associated with: Two annual cycles of the Pacific cold tongue under orbital precession

The Pacific cold tongue annual cycle in sea surface temperature is
presumed to be driven by Earth’s axial tilt and thus its
phasing should be fixed relative to the calendar. However, its
phase and amplitude change dramatically and consistently under various
configurations of orbital precession in several Earth System models. Here
we undertake Earth System model simulations and simulations of an
intermediate coupled model to investigate causes of this behavior. In
particular, simulations of the Community Earth System Model version 1.2
are carried out spanning the space of orbital eccentricity and longitude
of perihelion.  This dataset archives model output and analytical
codes used in this investigation. The results are reported in Chiang et
al. (2022), Two annual cycles of the Pacific cold tongue under orbital
precession.
