Campaign Data Surface reflectance (in-situ)

  • Surface nadir reflectance data measured with an ASD FieldSpec and a Spectralon panel, collected by the JPL and JAXA teams.
  • Data analyzed by Carol Bruegge (JPL, V0: 2009 - 2022) and JAXA (V1: 2009 - present, data through Fall 2025)
  • Descriptions of the V0 and V1 products:
    ・The reflectance calculation method is described in Bruegge et al. (2019, 2021).
    ・The outlier filtering for the V0 product was based on the fractional difference of each sample from the overall mean computed over the entire observation period. The V1 product filter is based on the deviation from a moving average calculated over a specific time interval.
    ・The V0 and V1 products are comparable, with a mean difference of less than 0.1% across all wavelengths on clear days.
