The goal is to estimate near-surface hydroclimate with higher plausibility to provide the background and preconditioning information for forest fire.

The approach is to focus on the snow scheme in a global climate model as a pivotal process, and improve it by use of the in situ and satellite snow observations. I will use the improved scheme for near-surface hydroclimate estimation.

Anticipated results are an improved snow scheme that can cover tundra and taiga zones, and better simulation/estimation of background hydroclimate states for assessment of the forest fire hazard.

This research will result in improvement and validation of the snow process and related physical property values (e.g., albedo, water content, density) in the physical terrestrial schemes.
