15. ULTRAVIOLET RADIATION AND CLOUD COVER AT MSL.

      Before looking at the REMS (Rover Environmental Monitoring Station)/NASA ultraviolet radiation data, it's important to understand that the criticism we offer here is unlike that found anywhere else because we have had an impact on the NASA data. NASA publishes their MSL data, we analyze it, and look for data off the (politically) expected curve. We then publish our color-coded spreadsheets complete with print screens of the odds NASA data, and wait for NASA to change the figures on their side. Almost always they do, although with respect to pressure, what they change is, we believe, still wrong by two orders of magnitude. When NASA alters its data we again capture it by print-screen and we publish that to prove that NASA takes its cues for what they can get away with from us.

     Where can you find our data with included printscreens? Here:

       Now, let's look at what NASA had published and revised for the first two Martian years of MSL operation and update it with what they currenly offer after three Martian years.  The next two tables show what we found after two Martian years there. A Martian has 669 sols (Martian days) with each about 37 minutes longer than an Earth day.

TABLE 23B

Table 23B shows µv for 1,256 MSL sols. This chart was prepared before we double checked medium and high µv values. The check was necessary because medium and high µv values were only distinguished with a slight color difference unless the µv icon was clicked (see Figure 24). Table 23C with the red background is what remains after the REMS Team eliminated all low µv values. We believe that its credibility is highly suspect.

Table 23 – Initial ultraviolet radiation reported through 2,007 sols at MSL. 

           Our initial exact count of medium and high µv values might have been slightly off because the REMS reports relied primarily on a color code to denote µv level, and the colors they chose for medium and high values were almost identical. We noted on 2/22/2016 that after a visit to our sites by the Finnish Meteorological Institute which, working for the REMS Team and NASA bears responsibility for all MSL weather instruments, all 19 low µv values were altered to N/A or medium. All low µv values after 2/22/2016 were also altered.  There were new low µv values posted by the REMS Team for Sols 1,610 and 1,611. We noted them on at http://marscorrect.com/photo4_19.html and have a print-screen of Sol 1,610 at http://marscorrect.com/images/sol_1610_error_fixed.png. Within three days of posting the low values JPL again altered them both (to Not Available). Evidently low pressure is not politically correct.

       The µv results shown on Tables 23B through 23D were a bit surprising. If we use a number of 5 to represent a µv index of extremely high, 4 for very high, 3 for high, 2 for medium, and 1 for low, then (ignoring 111 sols where there was no data on Table 23D, the average µv index was only about 2.8349 – between medium and high. This is surprisingly low because NASA often cites what sounds like extremely high radiation (due to its allegedly thin atmosphere, lack of an atmospheric ozone layer and lack of a magnetic field) as reason why it is so difficult for life to survive on the surface of Mars, however there are other types of radiation - not included on the REMS weather reports - that are supposedly measured by MSL Curiosity. In addition to identifying neutrons, gamma rays, protons, and alpha particles (subatomic fragments consisting of 2 protons and 2 neutrons, identical to helium nuclei, the Radiation Assessment Detector (RAD) RAD identifies heavy ions up to iron on the periodic table.

       While Viking 1, Viking 2 and MSL high pressure air measurements were close to perihelion (closest approach to the sun) as shown on Table 2 in Annex U (http://marscorrect.com/ANNEX%20U.pdf) of this report, the relationship of perihelion to UV was far less certain. Table 2 there details what the current JPL position is with respect to each sol’s Solar Longitude (Ls), pressure, and reported UV value. Before their major revision there were 4 categories given by JPL/the REMS team) for µv values found – low, moderate, high and very high. The revision only included moderate, high and very high. With respect to very high µv it was recorded on 175 sols in MSL Year 1, but only on 17 sols in MSL Year 2. In Year 3 there were 42 sols with very high µv for the summer.

      When I did a data check on 2/22/2016 I wasn’t surprised to find that I had made the wrong color judgment for about 10 sols, and the corrections were immediately made on my website spreadsheet for µv reports at http://marscorrect.com/photo2_17.html. However, I was shocked to find that after I went to a great deal of trouble to graphically illustrate exactly where Mars was in its orbit around the sun when low µv was reported, all 19 incidents had been removed by the REMS Team and NASA. We believe that this action is another response to critiques seen throughout our websites. Figure 75 in our Basic Report shows print-screen records of several low µv values before they were tossed out of what was presented to the public after all such data was massacred. But while we thought we had summed up in the µv situation with Figure 75, again REMS shocked us reading our Report and restored at least 12 low µv values by October, 2017. The restored data is captured on Figures 76A and 76B below. There were no low µv readings that survived NASA editing in Year 3.

       Why are low µv values problematic for NASA? One might think that with the ultra-thin atmosphere espoused by them, and no ozone layer, ultraviolet radiation on Mars would be extremely high on at least some days. But at least up to Sol 2066 on June 10, 2018 it never was, even though the REMS Team alleged that every single day at MSL so far has been “sunny.” However, this claim by the REMS Team is easily refuted with data provided by the Malin Space Science Systems.

       Why is the REMS Team indecisive about the idea of low µv values? Quite simply, 19 sols with low µv does not fit well with an atmosphere <1 % of Earth’s, no ozone layer, and clear sky. That NASA threw out all low µv values after they read our concerns makes their action all the more suspect, especially because they have thrown out all wind reports after our objections, changed their totally wrong sunrise and sunset times to match David Roffman’s calculations, and we document many changes made to their temperature and pressure data after we color- highlighted obvious concerns on our weather spreadsheets for MSL Years 1, 2, and 3 (see Table 23A above for links to all our data). Now again, after we recorded our observation of them removing low µv values, we record them read them reading our critique again and restoring most of these values. Eight years ago (now) Dr. David Roffman set out to understand Martian weather. At my suggestion, he wrote a simple 10-page paper (Case for Higher Than Advertised Martian Air Pressure – see http://davidaroffman.com/rich_text_6.html) for a technical writing course at Embry-Riddle Aeronautical University. That 10-page paper grew into this 1,030+/- page full Report (including our Annexes and Appendices). Indeed, with NASA and foreign space agencies constantly at our web sites reading the latest edition of this Report we can state that this Report is becoming a controlling factor in what NASA tells the world about Mars and in what the world believes about NASA’s credibility on this topic. As such, we never took down our graphics about the original low µv values posted by the REMS Team. We are right. NASA is wrong. They know it, and thus as Figures 1, 2 and 6 show, even on this they caved in to us and restored most of the low µv values.

Figure 2A shows the color for UV used on REMS reports. Figure 2B relates dose rate at MSL in micrograys per day to UV levels published on the REMS reports (see Table 2) for ~300 sols.

Perhaps because all REMS reports for at least 2,077 sols (3.1l Martian year) covered so far have opacity listed as “sunny,” we didn’t pay much attention to the UV readings until December, 2014.  We didn’t notice much variation in the UV intensity either. Perhaps this is because the UV Index scale in the United States, which conforms with international guidelines for UVI reporting established by the World Health Organization (WHO), has 11 numerical levels while only four levels are seen on the REMS reports. The WHO UVI index is color coded and divided as follows: 0 to 2: Low (low danger from the sun's UV rays for the average person), 3 to 5 : Moderate (moderate risk of harm from unprotected sun exposure), 6 to 7: High (high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed), 8 to 10: Very High (unprotected skin and eyes will be damaged and can burn quickly), and 11+: Extreme (unprotected skin and eyes can burn in minutes). There has not yet been an incident of extreme UV reported from MSL. Low UV is currently indicated for Sols 609, 619, 838, 839, 840, 841, 843,844, 800. 851, 853, 854, 855, 939, 1006, 1007, 1008, and 1021. Low UV was initially reported for Sols 829 (see Figure 1) and 833, but altered to moderate. Figure 2A below shows the REMS color scheme used for UV levels.

        Figure 2B, adapted from Hassler et al. (2014) shows ~300 sols of time series of radiation dose rate measured by Radiation Assessment Detector (RAD) on the surface of Mars and we have added to it the REMS Team reported UV index data for one incident of a hard Solar Energetic Particle (SEP) event on Sol 242, and four incidents of Forbush decreases due to soft SEP event related interplanetary coronal mass ejection (ICME) events. ICMEs are magnetic shields against galactic cosmic rays (GCRs), thus the observed flux is reduced. The REMS UV observations were added to Figure 2B to see if there was a correlation between what Hassler et al. showed and the UV reported. While the hard SEP was matched by very high UV, the Forbus decreases all occured when there was also very high UV.  A quick check of the Hassler et al. article showed no mention of UV. Although high frequencies of UV are considered to be ionizing radiation (radiation with enough energy to remove tightly bound electrons from atoms, thus creating ions); the article deals with galactic cosmic rays (GCRs) and solar energetic particles (SEPs). Both GCRs and SEPs interact with the atmosphere and, if energetic enough, penetrate into the Martian soil, or regolith, where they produce secondary particles (including neutrons and gamma rays) that contribute to the complex radiation environment on the Martian surface.
