SSiB generations:
SSiB-1: Biophysical processes
SSiB-2: Photosynthetic processes
SSiB-3: multilayer snow processes
SSiB-4/TRIFFID: Dynamic vegetation processes with heterogeneity consideration.

Sahel and East Asia suffered significant climate anomalies and land degradation during the 1980s. GCM with land degradation scenarios simulated the regional climate anomaly patterns.

Vegetation biophysical processes and East Asian and South American monsoon evolutions

Only the GCM with explicit vegetation biophysical processes simulate the proper monsoon evolution, including the northward jump of the East Asian monsoon, and large scale turning of low level circulation during the early monsoon stage, while the GCM with only soil processes fail to simulate these features.

The river runoff data is interpolated to the regular grid. The first summer runoff SVD mode, SVD1r, shows a homogeneous drying trend but with strong emphasis in northern China to the warming in the Indian Ocean and eastern Pacific, different from the heterogeneous response of precipitation in SVD1p, a dry-wet-dry pattern. 

The Eta/SSiB model produces more realistic monthly mean precipitation over the U.S. and the flood areas. Even with a short-term simulation (24-hour), a more realistic representation of land-surface processes improves the monthly means of the simulated regional precipitation for the summer of 1993.

Use TVX concept, AVHRR data, and SSiB, soil moisture in HAPEX-Mobilhy site is derived.

In a North American study, the Eta/SSiB regional climate model while forced by the reanalysis shows limited summer-season downscaling ability under certain conditions, which include model domain size, the position of model boundaries, model horizontal resolution, and model initial conditions.
