Table 1. Monthly averaged surface air temperatures and precipitation over land in January and July at 15° latitude intervals before and after the soot ejection from the impact accompanied by the estimated latitudinal areas and seasons of survival and extinction of the dinosaurs and crocodilians.

^*Latest Cretaceous monthly mean land surface air temperature after average values from the BESTGUESS and BARESOIL simulations⁴⁰.^#Late Cretaceous monthly mean land precipitation from the GENESIS (v2.0) data⁴¹.⁺Estimates by subtracting the maximum decreasing land surface air temperatures and land precipitation of the climate model calculations of this study (Fig. 3) from the latest Cretaceous land surface air temperature and the late Cretaceous land precipitation (average within the range), respectively. The areas of survival of most of the dinosaurs are shown in green (>15 °C, >1.0 mm/day). The areas of survival of the crocodilians are shown in green and blue (>15 °C). Pale green and blue areas indicate the areas of survival considering a 2 °C error (>13 °C). Low precipitation (<0.1 mm/day) during half year corresponds to areas of survival. Gray areas indicate those where the dinosaurs and crocodilians did not survive.
