This archive contains simulation output from the Mars Climate Modeling Center's Legacy Mars Global Climate Model (MGCM). These simulations cover one full Mars Year at a resolution of 6° of longitude by 5° of latitude. Data is stored in 10-sol (10 martian day) increments at 1.5 hr time intervals. The files are referenced by their beginning and end solar longitude (Ls), which is Ls=0° at the beginning of Mars' northern spring. One simulation (ACTIVECLDS) includes radiatively active clouds, and one simulation (INERTCLDS) includes radiatively inert clouds. Details for the simulations are presented in a reference paper by Haberle et al. (2019).
