The NASA-Ames Mars General Circulation Model (MGCM) CLimate Catalog was developed in support of the on-going Mars Global Surveyor (MGS) Mission.

MGS's mapping orbit is such that the spacecraft passes overhead at 2am and 2pm (LST) every day. Hence, many of our products are geared toward conditions at those times.

MGS is scheduled to be in orbit for one Mars year, and thus products are available for all times through Mars' year.
