• Update information of the data:
  • [2025-04-11] The data from 2024 Apr 1 to 2024 Aug 30 are released. An additional NOTICE: A few small artificial jumps were not cleaned in the previously released data of 2023 Jul - 2024 Mar. The affected data are now updated with v03r01.
  • [2024-12-07] The data from 2023 Dec 1 to 2024 Mar 31 are released.
  • [2024-09-22] The calibrated data both in 32Hz and 1Hz from 2023 Apr 6 to 2023 Nov 1 are released. Since 2023, MOMAG is running in 32Hz mode all the time, and the position of spacecraft in the data files is given in units of km instead of R_M.
  • [2024-06-06] The calibrated 32Hz data from 2021 Nov 16 to 2022 Nov 3 are released. During this period, the 32Hz data were only collected for two hours near the periareion, which was 215-273 km above the Martian surface, and for one hour near the apoareion, 10743-10801 km away from the Martian surface.
  • [2024-05-26] Updated to version 03 due to the bug in processing the time tags. The times in the v03 data increase 7s or 1s compared to the v02 data.
  • [2024-03-13] The data of 2022 Nov 4 and 5 are removed due to wrong orbital information. MOMAG was out of operation after then until 2023 Apr 6.
  • [2024-03-11] The data from 2022 Jul 1 to 2022 Nov 5 are released.
  • [2024-01-29] Those unreal jumps in previous version of the data have been removed. The version is updated to v02r01.
  • [2024-01-19] The MOMAG data are found to contain some unreal jumps occasionally due to the bugs in the procedures processing MOMAG data. Please interpret the data in caution. These bugs will be fixed soon.
  • [2024-01-04] The second version of the calibrated MOMAG data from 2021 Nov 16 to 2022 Jun 30 are released. The difference between this v02 and previous v01 data is small. The v02 data are calibrated based on the method in Wang et al. 2024 while the v01 data based on Zou et al. 2023.
