2 dimensional image data of 256 gray scale levels (1 byte) that exhibit reflected echo strength of a sounder observation along a satellite orbit. The horizontal axis represents satellite flight direction, while the vertical axis is the distance from the satellite, namely the depth in the lunar interior below the lunar surface. Large echo intensities indicate the lunar surface and discontinuities below the lunar surface. This data product corresponds to B-scan image, which can be produced by arranging A-scope images along a satellite orbit. An A-scope image can be generated by FFT processing of a received raw signal of Sounder operation. The spatial resolution along a satellite orbit is 75m. The spatial resolution in the range direction (depth direction) is about 75m. One file is for a region of about 1000 km (10 minutes observation) along a satellite orbit.

Request for using this data

When you publish your work on SELENE(KAGUYA) data, we would like to ask you to acknowledge the appropriate instrument team(s) and the SELENE Data Archive as follows. For instance, if you use the SELENE(KAGUYA) TC data, the following would be an appropriate acknowledgement:

“We thank the SELENE(KAGUYA) TC team and the SELENE Data Archive for providing the SELENE(KAGUYA) data. SELENE is a Japanese mission developed and operated by JAXA.”
