Nightside surface temperature of Venus with spatial resolution of 0.5° × 0.5°. Surface temperature retrievals are based on IR1 data from Akatsuki mission between July 21, 2016 and December 7, 2016. White areas indicate either data is absent or erroneous. High altitude regions are relatively colder than low altitude regions (Data source: https://darts.jaxa.jp/planet/project/akatsuki/ir1.html.en)^6,25.
