Introduction

The dataset of land surface forcing field for China Mainland, in the period of 1958 to 2010*, is provided.

The dataset consists of 7 components: near-surface air temperature, near surface air pressure, near surface relative humility, wind speed, rainfall rate, downward longwave radiation and downward shortwave radiation.

The temporal-spatial resolution of this dataset is 3hr and 5km.

The documentation for this dataset can be downloaded here, including readme, geographic_information for the products, technical_details for the method we use and the analysis of the results, and format-conversion program by Visual FORTRAN 6.5.

*Because of the limitation of the storage of our current system, we only provide the data for 2000 to 2010, and we will upload the rest as soon as possible.
