March 2, 20214 yr The MSL ChemCam Passive Surface Spectra Bundle is released at the PDS Geosciences Node. This bundle contains MSL ChemCam passive surface spectra calibrated to units of radiance and relative reflectance, along with a metadata table populated for each ChemCam passive spectrum. The data were generated by Jeff Johnson, Johns Hopkins University Applied Physics Laboratory, and funded by the NASA Planetary Data Archiving, Restoration, and Tools program (PDART).
