This page updated on 3/21/2016 after NASA dropped all low UV values and again on 5/5/2016.

This article reveals all Mars Science Laboratory (MSL) weather data for MSL’s Mars Year 2 summer. It shows what was published by the Rover Environmental Monitoring Station (REMS) Team and JPL. It also reveals what the Roffman Team sees as weather anomalies, and how the REMS Team and JPL altered their data after we color-highlighted what was off the expected temperature and pressure curves. In February, 2016 we noticed that after we made a big deal of all the low UV values and how hard they were to explain, NASA dropped them all - changing them either to medium or not available.

Figure 1 - MSL pressure data leading up to Ls 270, the start of MSL's second summer in the southern hemisphere of Mars. Also shown are the pressures published by NASA for Viking 1 and 2 plus Phoenix.

On Table 1 column subjects and color codings are as follows:

Column A (Sol). The Martian day is about 39 minutes longer than the terrestrial day.

Column B is solar longitude (Ls). MSL is in the Southern Hemisphere on Mars. The landing was at Ls 150 in winter. Ls 180 begins the spring there.  Ls 270 starts summer, Ls 0 starts the fall. Ls 90 starts the winter.

Column C shows the pressure reported by the REMS Team.

Column D shows the date on Earth.

Column E shows the maximum air temperature. With respect to the freezing point, from 0° C at 1 atm pressure it will increase up to 0.01° C at 0.006 atm (which is about the average pressure on Mars as given by NASA). This is the triple point of water. At pressures below this, water will never be liquid. It will change directly between solid and gas phase (sublimation). The temperature for this phase change, the sublimation point, will decrease as the pressure is further decreased

Column F shows minimum air temperature.

Column G shows the air temperature range for each sol. On Earth temperatures can vary by 40 °C in deserts. In column G where the range is 59 °C or less yellow background coloring points that out. The National Park Service claims the world record in a diurnal temperature variation is 102 °F (57 °C) (from 46 °F (8 °C) to −56 °F (−49 °C)) in Browning, Montana (elevation 4,377 feet/1,334 meters) on January 23 to 24, 1916. There were 2 days in Montana where the temperature changed by 57 °C.

Column H shows temperature range divided by 40. This allows us to compare terrestrial deserts with Gale Crater, Mars. How much cooling occurs at night is related to the density of the atmosphere. Here we see the ratio of cooling on a Mars sol to the typical 40 °C cooling figure for Earth's deserts shown with a green background when that ratio is under 1.5. For MSY Year 1 when we altered the devisor from 40 °C  to 57 °C then 88 of the ratios were altered to 1 or less than 1, meaning that Martian air pressure is indeed likely much higher than NASA claims.

Column I shows maximum ground temperature. As with terrestrial deserts, the ground on Mars heats more during the day than the air does, and it cools more at night than the air does. In Column K when the maximum ground temperature is given by REMS is above 0°C it is shown with a red background.

Column J shows the minimum ground temperature. When it is -90 °C or colder the background is in purple. The ground temperatures are not very precise. The requirement was to measure ground brightness temperature over the range from 150 to 300 K with a resolution of 2 K and an accuracy of 10 K

Column K. Drop in ground temperature from day to night.

Column L shows the increase in temperature from the mast 1.5 meters above the ground down to the ground during the daylight hours. In column N anytime there is an increase in temperature of 11 °C or more this in indicated with a dark blue background.

 

Column M shows the decrease in temperature from the ground to the air at nights. If the data were valid we would expect similar heating or cooling to occur over the set distance from ground to boom. A quick survey of the data immediately shows that this was not found. In column L we see a variation in heating between 0 °C and at least 15 °C with a 54 °C anomaly on Sol 1,070. For nighttime cooling any variation from 11°C to 19°C is shown with a medium blue background. More than that is shown with a dark blue background.

Column N shows the pressure for the same Ls in MSL Year 1.

Column O shows the absolute value of the change in pressure in Pascals from the same Ls in the previous year (Column [M] - [C]).

Column P shows the original pressure for the same Ls in MSL Year 1 before JPL revised their data.

Column Q shows the Ls during Year 1.

Column R shows the UV for the sol in Year 2.

Column S shows the UV for the sol in Year 1. All sols in MSL Year 1 and Year 2 have opacity listed as “sunny” which seems dubious.

Column T shows comments, if any.

 

 
 Note: After Sol 880 data in columns N. O, P and S is off by one Sol/row and is in the process of being repaired.

Figure 2 below: The low temperatures for Sol 880 were too warm by previous standards. However the previous days no data was posted for Sols 873 to 879, so it is possible that the instrumentation was down or the signals were blocked. If so, this data for Sol 880 might be only partial for that sol and not include the true low. Should that be the case, a change to N/A would be both necessary and fully justified. The REMSTeam and JPL should include such concerns with the reports they publish. Failure to do so casts further doubt on their credibility. The right below is what they presented to the public the next day, After we duplicated the questionable temperatures, JPL revised them down appreciably and raised the pressure a good bit too.

Figure 3 - REMS Team and JPL continue to revise data after we highlight anomalies.

Figure 4 - Mistakes and significant data alterations early on cast real doubt on the accuracy or honesty of MSL weather data.

FIGURE 5 - REMS TEMPORARILY REVISES (TRASHES) ALL ITS PRESSURE DATA AFTER 954 SOLS. They did this while we were was in the process of transferring their data to my data base. Soon (within 12 hours) after we posted the chart below, they reverted to their previous daily reports. REMS has often reacted quickly to the data that we post.
