Data

The following links contain data for GISS model simulations run for CO2 concentrations of 0.5, 1, 2 and 4 times preindustrial levels.  Data includes mean state and regression maps for MJO-related anomalies for surface and pressure level variables. For info on the data and results, read Adames et al. (2017, a,b), JAMES.
