This dataset is a global map of the land surface dry deposition rate of atmospheric hydrogen calculated by the Japanese climate model MIROC. In this calculation, In MIROC, CHASER was used as the chemical model component, and MATSIRO was used as the land surface model component. Using the land surface conditions (soil moisture content, soil temperature, ground surface wind speed, etc.) calculated online, the hydrogen consumption intensity by enzymes in the soil and the vertical diffusion coefficient into the soil was calculated.
