One column radiative-convective model

This interface allows you to run a one-column climate model. The model calculates the evolution of temperature, humidity, and radiative and convective fluxes through the column based on specified values of the incoming solar radiation and greenhouse-gas concentrations and a specified initial condition. The model will look for previously run simulations in its cache, but please be patient - simulations may take up to a minute to complete if they are not cached.
