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.

 

 
Correction Note: On 3/20/2016. Due to an error in row, data was one row off before corrections to columns M,N, O and S before this date. Data on the table below has been corrected. These corrections must still be made to the same columns on the earlier data sets from Sol 880 to Sol 121.

Note: Prediction made on Sol 1323 about Ls of minimum pressures was accessed by NASA San Diego               IP addess 192.194.122.7 on  5/4/2016 at http://marscorrect.com/custom3_6.html.

Sol 1329 was the first sol in the Year 2 winter with an identical pressure to Year 1 (735 Pa).

In the MSL Autumn YEAR 2 data there was only 1 sol (1145) with an initial report of idetical pressure to the previous year. Based on highly unusual temperatures we predicted that JPL would alter the data and they did. Pressure on Sol 1145 was altered from 907 Pa to 903 Pa. The temperatures were also altered (see http://davidaroffman.com/photo2_30.html).

The last agreement between pressures on identical sols was for the summer season, but NASA has altered some pressures on a continuing basis.

PREDICTION MADE ON APRIL 29, 2016: At this rate JPL should claim a Year 2 minimum pressure of about 728 to 730 Pa around Ls 147 to 150 between MSL Sols 1332 and 1338. Note: MSL had its minimum pressure in its Year 1 at 732 Pa at Ls 147.

REALITY CHECK ON MAY 14, 2016: MSL had its Year 2 minimum pressure at Ls 148 to 149 on its Sols  1334, 1335 and 1336.  So the timing of the prediction for minimum pressure was exactly correct. The pressure recorded for these dates was 732 Pa (rather than the 728 to 730 Pa predicted above).  Pressure had been running about 2 to 4 Pa lower for Year 2 than Year 1, however the 732 Pa minimum pressure for Year 2 EXACTLY matched the 732 Pa minimum pressure for Year 1.  Likewise the  maximum pressure for MSL Years 1 and 2 was identical at 925 Pa (but only after several revisions of REMS data) although the Ls of maximum pressure varied from 252 on Year 1 to 257 on Year 2.  Not yet factored in: we would expect pressures recorded to drop as MSL climbs Mount Sharp.  That there is no difference at all between maximum pressures for MSL Year 1 and Year 2 and again no difference at all between minimum pressures for MSL Years 1 and 2 is highly suspicious which is why we view the prediction as more psychological/political than meteorological. A Martian Year is 668.5891 sols/686.98 Earth days.

Figure 1 - On Sol 1,222 the ground temperature reported reached the freezing point of water/melting point of ice even though this was just a few days after the winter solstice. There was no such warming at night, with a low of -94 degrees Celsius -137.2 degrees Fahrenheit. The data suggests a broken temperature sensor. The daytime ground temperature went above freezing for sols 1224, 1226, 1227, 1228 and 1229 but the night ground temperatures got even colder.

 

Figure 2 - REMS weather reports published for MSL Sols 1234 to 1241. Note all the ground temperature highs above 0 degrees Celsius and the incredibly low ground temperature at night - down to -100 degrees Celsius on Sol 1241. We think this is evidence for broken ground temperature sensors, or failure to factor in the very poor accuracy of the ground temperature sensor (10K/10 degrees Celsius/18 degrees Fahrenheit). Don't be surprised if this report again forces REMS and JPL to revise its published data. They would be smarter to simply hire us to fix their many problems. Until this happens or until they directly publish our audit of their wacky data they have zero credibility.

Figure 4 and above freezing temperatures in the early winter of MSL Year 2: Here is data that we gathered and placed in our article about high temperatures: As of February 9, 2016 it appears that the high air or ground temperature is above 0° C at Gale Crater on at least 406 days of the 669 sols in a Martian year. This number surprisingly increased in early winter of MSL Year 2 on 16 sols between Ls 95 and 104 with above freezing ground temperatures  of +1, +1, +2, +1, +1, +1, +1, +1, +1, +2, +2, +2, +3, +1, +2 and +1 °C found where in Year 1 the ground temperatures on those days were -7, -6, -3, -6, -5, -9, -11, -8, -8, -13, -7, -7, -8, -8, -10 and -9° C. There were also five sols (1222, 1223, 1230, 1237 an 1244) at Ls 94, 98, 101 and 104 where the ground temperature in Year 2 was 0° C while in Year 1 it was in °C only -10, -7 -5, -9 and -10° C . A quick summary for this 24-sol period each year is as  follows:

Figure 3 - Pressure on Sols 1300 and 1301 spiked up to records amounts. This will likely be removed by JPL. Location of MSL on Sols 1300 an 1301 is shown on Figure 4.

 

Figure 4 - Location of MSL when the REMS Team published large pressure spikes for Sols 1300 and 1301. Altitude change did NOT account for the changes.

 

Figure 5 - Once again the REMS Team shows us a pressure spike on Sol 1301 that is above the 1150 capacity of the Vaisala pressure sensor on MSL. They have a record of going back and revising these pressures down. Will they do it again? They do show pressure for Sol 1302 back to normal.

 

Figure 6 - The answer to the question in Figure 5 is yes, once again JPL and REMS threw out data off the curve, and put it right back on. Data like this should be considered behavioral or politicial. It is not meteorological. It demonstrates why none of the NASA Mars weather data is trustworthy. It will likely remain untustwothy unless the Roffman Mars Correct Team is hired to fix fatal flaws in NASA's weather data collection program.
