This data is for MSL Year 2 Solar Longitude 151 to 270 (late winter to the end of spring). Updated 2/25/2016 after we caught the REMS Team/JPL dropping all low UV values for from the landing up through MSL Sol 1261. Their action was taken after they had reviewed our spreadsheets like that below, and our articles questioning low UV values on Mars.

     The pressure data for MSL's Year One plus Viking 1, Viking 2 and Phoenix is summarized on Figure 1. The full weather data for MSL Year One is HERE. Table 1 under Figure 1 sums up weather data so far for MSL Year 2.

       Note that MSL Year 1 and Year 2 both share a maximum pressure of 925 Pa. So far they also share a minimum pressure of 732 Pa. This MSL pressure chart, based on a lander close to the Martian equator (MSL is at 4.59° South), is especially of interest because Year 1 shows two pressure spikes that occur almost a half Martian year apart. The first spike is at MSL Sol 170 to 171 at Solar Longitude (Ls) 252. As just noted, the (revised) pressure published was 925 Pa. The second spike was at MSL Sol 469 when Mars was at Ls 56. That's 164° later in its orbit. The pressure then was 908 Pa which is 98.16% of what it was when the first spike was seen. The first spike occurred almost exactly when Mars was at perihelion at Ls 251 (closest approach to the sun) and in the late spring where MSL sits in the southern hemisphere. Summer in the Martian south begins at Ls 270. The second (908 Pa) spike at Ls 56 was in the southern hemisphere's fall season. Pressure at aphelion (Ls 71 when Mars was at it further point from the sun) was still 898 Pa, which is 97.29 % of its perihelion value of 923 Pa. If, as was once thought, both Martian poles were frozen carbon dioxide, we would not be surprised to see that a lander close to the equator showed two similar pressure spikes 180°apart, with each one reflecting frozen carbon dioxide at the summer pole sublimating and returning the gaseous state. However, we now know that there is very little frozen carbon dioxide at the North Pole. The ice there is mostly water ice. The frozen carbon dioxide is mostly in the Martian Antarctic (offset from the South Pole). We show throughout this site that all Martian air pressure data is suspect due, probably due to faulty pressure transducer design that did not allow for very tiny dust filters to clog with dust immediately upon touchdown. It is also possible that the data published by NASA is deliberate disinformation. We document several cases where JPL altered its MSL weather data AFTER seeing our criticism of it. The most recent such alteration is shown on Figure 2 below after Table 1. 

Figure 1 above summarizes MSL pressure data up through its Sol 866, Ls 270 - start of the second summer at MSL.

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.

Figure 2 Statement by Barry S. Roffman - Sol 829 shows how NASA/JPL altered data after Table 1 color-highlighted data that was off the expected curve. This pattern suggests that NASA is not always publishing real data. Rather it is publishing data in response to this web site. While this web site is maintained out of the City of Cape Canaveral, Florida, we have no formal relationship with NASA, although we would do HONEST work for them, Mars One, or any space program not hostile to the United States if asked to do so.

Figure 3 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.
