[PPS23-P03] Three-dimensional lunar mare subsurface structures based on the SELENE radar soundering
The Lunar Radar Sounder (LRS) onboard the SELENE spacecraft carried out the global exploration of lunar mare subsurface structures by radiating the electromagnetic wave (4-6 MHz) and detecting the reflectors from the surface and subsurface boundary [Ono et al., 2009]. Compared to the LRS data with the preexisting geological maps, previous studies have been discussed the eruption flux of the lava flow [Oshigami et al., 2014] and geological condition (i.e., porosity and density) of the mare region [Ishiyama et al., 2013]. In order to merge the subsurface information into the geological map, we investigated the depth of the subsurface reflectors at the interval of 1 deg. in latitude and < ~2 deg. in longitude and produced the three-dimensional database of the subsurface structures. In the presentation, we will show three-dimensional mare subsurface structures found in this study.
