Does someone know where to find a (hopefully modern) version of the numerical code for solving the 1D atmospheric thermal equilibrium model, the one Syukuro Manabe & Richard T. Wetherald used in their seminal 1967 publication in J.Atmosph.Sciences ? (doi:10.1175/1520-0469(1967)024<0241:TEOTAW>2.0.CO;2). I guess with modern computers it's a matter of seconds to solve, and redo the calculations from their work, and I'ld be pleased to use this in my math for Earth sciences course, as an example (university, 2nd year).
