This dataset collection contains basic gridded atmospheric and surface variables for the planet Mars over three Martian years (a martian year is 1.88 terrestrial years), as produced by data assimilation of spacecraft observations. Each file in the dataset spans 30 martian mean solar days (sols) during the science mapping phase of the National Aeronautics and Space Administrations's (NASA) Mars Global Surveyor (MGS) spacecraft, between May 1999 and August 2004. The dataset collection was produced by the re-analysis of Thermal Emission Spectrometer (TES) retrievals of nadir thermal profiles and total dust opacities, using the Mars Analysis Correction Data Assimilation (MACDA) scheme in a Mars global circulation model (MGCM). The MGCM used the UK spectral version of the model developed by the Laboratoire de Météorologie Dynamique (LMD) in Paris, France. MACDA was a collaboration between the University of Oxford and The Open University in the UK.

This dataset contains basic gridded atmospheric and surface variables for the planet Mars over three martian years (a martian year is 1.88 terrestrial years), produced as a reference run in association with the Mars Analysis Correction Data Assimilation (MACDA) v1.0 re-analysis. Each file in the dataset spans 30 martian mean solar days (sols) during the science mapping phase of the National Aeronautics and Space Administration's (NASA) Mars Global Surveyor (MGS) spacecraft, between May 1999 and August 2004. This dataset is a reference run produced by re-analysis of Thermal Emission Spectrometer (TES) retrievals of only total dust opacities, using the MACDA scheme in a Mars global circulation model (MGCM). This reference dataset, therefore, should be used in association with the full re-analysis of TES retrievals of nadir thermal profiles and total dust opacities - see linked dataset. The MGCM used is the UK spectral version of the model developed by the Laboratoire de Météorologie Dynamique in Paris, France. MACDA is a collaboration between the University of Oxford and The Open University in the UK.

This dataset includes measurements of protodune and barchan height, length and migration on both Mars and Earth. Earth measurements were calculated from high resolution Terrestrial Laser Scans (TLS) of bedforms migrating through time in coastal and desert regions. Raw point cloud data can be found at Nield et al. (2023a; 2023b; 2025a; 2025b). Mars measurements were calculated from High-Resolution Imaging Science Experiment (HiRISE) imagery.
