Adomas Valantinas

Planetary scientist. Senior Fellow at the Leverhulme Centre for Life in the Universe, University of Cambridge. I work on the iron chemistry and mineralogy of the Martian surface with orbital spectroscopy and imaging (CRISM, CaSSIS, HiRISE, THEMIS), laboratory experiments and machine learning, and on lunar infrared data (M3, Kaguya, Chandrayaan-2 IIRS).

Paper code and data

Tools (Python, MIT, tested)

  • pycrism: CRISM summary parameters, cube readers and browse products in pure NumPy
  • m3-spectral-toolkit: Moon Mineralogy Mapper reader, band parameters, thermal correction, Hapke single-scattering albedo and mixing
  • lunar-ir-data-tools: Kaguya Spectral Profiler and Multiband Imager, Chandrayaan-2 IIRS readers and corrections
  • cassis-colour-toolkit: CaSSIS colour cubes, 30 colour and spectral-shape parameters, RGB composites
  • tes-destripe: orbit-track destriping of MGS TES global maps
  • themis-ti-mosaic-tools: download, verify and repair the THEMIS global thermal inertia mosaic
  • mars-hrsc-catalogue: catalogue and resumable downloader for the DLR HRSC mosaics
