Long-term Increase in Equatorial Rayleigh-Taylor Instability: Synergistic Effects of Greenhouse Gas Cooling and Geomagnetic Field Secular Variation

Description

1. Five JPEG image files These are the figures in the paper. 2. Five IDL programs that plot the figures. 3. IDL sav data: These data are in IDL sav format. RTI_1965_2014_combined_case1.sav: equatorial fieldline integrated Rayleigh–Taylor Instability (RTI); ratio of F-region Pedersen conductivity to the total; plasma-drift in the magnetic meridian plane and perpendicular to the magnetic field (positive upward/outward), field (positive upward/outward); corresponding neutral-wind component (positive upward/outward); the effective gravity–collision term (scalar magnitude); the normalized plasma density gradient; the effective recombination rate, simulated by WACCM-X, driven by greenhouse gas forcing alone; RTI_1965_2014_combined_case2.sav: equatorial fieldline integrated Rayleigh–Taylor Instability (RTI); ratio of F-region Pedersen conductivity to the total; plasma-drift in the magnetic meridian plane and perpendicular to the magnetic field (positive upward/outward), field (positive upward/outward); corresponding neutral-wind component (positive upward/outward); the effective gravity–collision term (scalar magnitude); the normalized plasma density gradient; the effective recombination rate, simulated by WACCM-X, driven by greenhouse gas forcing and secular change of the earth's magnetic field.

Steps to reproduce

1. Download the idl programs and the idl sav data 2. Each program will read the sav data and plot one of the figures
