UPDATED APRIL 27, 2017. In addition to posting constantly wrong and never changing sunrise and sunset times for the Mars Science Laboratory Curiosity, Ashima Research and the REMS Team often mislabeled the dates and associated MSL Sols for the weather data supposedly coming back from Mars. This Table below details the history of these errors between August 22, 2012 (Sol 15) and January 2, 2013 (Sol 146). This information may be useful for data set references purposes when evaluating data from the MSL. It appears that Ashima went our of business, or at least out of the business of posting REMS weather data over a year ago. The REMS Team continues to post weather data, but often with ludicrous information. You can track our record of their reports (as well as changes in data that they make in response to our critiques) at the links provided for Table 2.

  

TABLE 1 – ASHIMA DATA ERRORS UP THROUGH JANUARY 2, 2013

NOTE: Most of these mistakes which were posted by us on January 2, 2013 were repaired by May, 2013, but as we indicate above in conjunction with Ls 90, such errors in reporting do continue into 2014.

Nov 21 (Sol  105), 22 (Sol 106), 23 (Sol 107) and 24 (Sol 108) Missing. Nov 25, shown as Sol 108 should be Sol 109.   Both Ashima and REMS report Sol 108 as November 25. Sol 109 and 110 missing.

Ashima reports this Sol at Ls 221. In reality November 24 is Sol 108 at Ls 212.4 and November 25 is Sol 109 at Ls 213.1. There is no pressure or other data reported out for the previous 4 days when a regional dust storm was southwest of MSL.
