黑河流域3公里6小时模拟气象强迫数据（1980-2010）

以中国科学院大气物理研究所东亚区域气候-环境重点实验室发展具有独立版权的区域集成环境系统模式RIEMS 2.0为基础，其中RIEMS 2.0区域气候模式是以美国大气研究中心和美国滨州大学发展的中尺度模式（MM5）为非静力动力框架，耦合了一些研究气候所需的物理过程方案。这些过程包括生物圈-大气圈输送方案、采用FC80闭合方案的Grell积云参数化方案、MRF行星边界条件和修改的CCM3辐射方等，采用黑河流域流域观测和遥感数据对该模式中的重要参数进行重新率定，并植被资料采用黑河流域数据清单中2000年土地利用数据和黑河流域30sec DEM数据，建立的起来适合黑河流域生态-水文过程研究的区域气候模式。

This regional climate model is developed based on the Regional Integrated Environmental Model System 2.0 (RIEMS 2.0) with independent copyright, which was developed by the Key Laboratory of Regional Climate-Environment for East Asia, Institute of Atmospheric Physics, Chinese Academy of Sciences. The RIEMS 2.0 regional climate model adopts the non-hydrostatic dynamic framework from the Mesoscale Model 5 (MM5) developed by the National Center for Atmospheric Research (NCAR) and Pennsylvania State University, and couples multiple physical process schemes required for climate research, including the biosphere-atmosphere transfer scheme, the Grell cumulus parameterization scheme with FC80 closure, the MRF planetary boundary layer scheme, and the modified CCM3 radiation scheme, etc. Important parameters in the model were recalibrated using observational and remote sensing data from the Heihe River Basin, while the vegetation data used the 2000 land use data from the Heihe River Basin data inventory and the 30-sec DEM data of the Heihe River Basin. Thus, this model is suitable for research on ecological and hydrological processes in the Heihe River Basin.

Spatial Scope: The grid center of the simulation domain is located at (40.30°N, 99.50°E), with a horizontal resolution of 3 km. The model grid dimensions are 161 (meridional) × 201 (zonal).

Projection Method: Lambert Conformal Conic projection, with two standard latitudes at 30°N and 60°N.

Temporal Scope: From January 1, 1980 to December 31, 2010, with a time interval of 6 hours.

File Content Description: Stored in monthly unformatted files via GrADS. Except for maximum and minimum temperatures which are on a daily scale, all other variables are 6-hourly data. The data can be read using MATLAB, please refer to the documentation in the tmax_erain_xiong_heihe.m file for details.
