Allison, M., J.D. Ross, and N. Solomon, 1999: Mapping the Martian meteorology. In Fifth International Conference on Mars, LPI Contribution No. 972. Lunar and Planetary Institute.
The Mars-adapted version of the NASA/GISS general circulation model (GCM) has been applied to the hourly/daily simulation of the planet's meteorology over several seasonal orbits. The current running version of the model includes a diurnal solar cycle, CO2 sublimation, and a mature parameterization of upper level wave drag with a vertical domain extending from the surface up to the 6μb level. The benchmark simulations provide a four-dimensional archive for the comparative evaluation of various schemes for the retrieval of winds from anticipated polar orbiter measurements of temperatures by the Pressure Modulator Infrared Radiometer [1]of the surface wind vector, as in the Tantalus Fossae region to the north of the Tharsis ridge and the Thaumasia Fossae region to the south of the Solis Planum. Others exhibit instead a semi-steady flow structure, as in the sinuous core of the famously simulated surface westerly at 30°S latitude [7], apparently strongest in the GISS simulations between 100 and 200°West longitude, and in the region extending from Noachis west to the Nirgal Vallis. The meridional flow is variably northerly at almost every longitude just to the south of the equator, consistent with a rising branch of the Hadley circulation near the sub-solar latitude.
