Abstract： The objective of this project is to develop the climate modelling techniques， in which the new 3D canopy radiative transfer model will be used to replace the two-stream approximations for radiative transfer of CoLM； the dynamic global vegetation model （DGVM） was implemented in CoLM. The hourly atmospheric forcing data between 2005 and 2010 were produced for relative humidity， air pressure， air temperature， wind speed （U，V）， precipitation， incident shortwave radiation， incident longwave radiation. The soil properties and plant functional type properties were also prepared. A high resolution land data assimilation system （HDAS） for multi-sources remote sensing data was developed. HDAS includes several kinds of data assimilation algorithms， and was designed for high performance computing. The multi-sources remote sensing data can be merged into land surface model （CoLM） within HDAS to produce the land surface data sets with 5 km spatial resolution and 1 hour temporal resolution between 2005 and 2010.

Key Words： Common land model； CoLM； DGVM； Land data assimilation system； Multi-sources remote sensing
