Our model temperatures compared to temperatures derived from Diviner data. (a–d) North pole and (e–h) South pole. (a),(e) DTM for which temperatures were modeled. (b),(f) Model temperatures at exact times of Diviner measurements. (c),(g) Diviner measurements taken on February 2, 2010, in (a) from orbit 2763 at 01:20 am and in (b) from orbit 2762 at 00:30 am. (d),(h) The difference between the model temperatures and the Diviner measurements. We note that no interpolation was used. Maps are displayed in polar gnomonic map projection and are color-coded by height (a),(e) and temperature (b–d),(f–h). For context the footprints of the Diviner measurements are indicated as black lines in (a),(b) and (e),(f).
