Description:
2.02-micrometer mapped data taken by the IR2 camera onboard Akatsuki in Level-3 netCDF format. The data have been corrected for the point-spread function, the flat-field pattern, and the detector temperature dependence by Sato et al. (2020, Icarus, 345, 113682, https://doi.org/10.1016/j.icarus.2020.113682).

Format (binary file):
netCDF
The file names indicate the year, date and time of each observation.
