First up the REM that is the metrological unit had a download anomaly on sol 1. It was deemed healthy on sol 0. The anomaly was found to be a software issue between the various data flow rates and protocol between separate orbiters. New software programs have been uploaded to Curiosity to correct this Comm. Issue.
Sol 1 data from the REM was shown to be above the anticipated model outputs. No thermal data has been released but during the 1:00 EDT briefing it will not hurt operations. In contrast the energy planned for seems to be below what will be needed.
No pressures have been release but the landing site is -4500 ft. below Mars sea level. The first NAVCAM image shows possible inversions and associated haze along the mountains to the North. Because of the above temperature anomalies this is most likely dust. Humidity data not yet released would rule out fog.
