The seasonal cycles of tropical sea surface temperature from Earth's axial tilt and orbital eccentricity

We explore the relative roles of Earth’s axial tilt (‘tilt effect’) and orbital eccentricity (‘distance effect’) on the seasonal cycle of tropical sea surface temperature (SST), decomposing the two contributions using simulations of an Earth System model varying eccentricity and longitude of perihelion.  This dataset archives model output produced in this investigation using the Community Earth System Model version 2, and MATLAB code for analyzing the data.
