Oct 24, 2020Abstract. Soil moisture is a key variable of land surface hydrology, and its correct representation in land surface models is crucial for local to global climate predictions. The errors may come from the model itself (structure and parameterization) but also from the meteorological forcing used.

Indoor particle losses are particularly effective in reducing ultrafine PNC, and maximum particle losses are around 10–20 nm with a median loss rate of around 1.1 h –1. In the 10–20 nm size range, particle losses are mainly caused by diffusion to any surface in the room.
