“黑河地区地一气相互作用野外观测实验研究（HEIFE）”，是在河西走廊黑河流域中段一个70km×90km范围实验区内进行的以水份和热量交换为中心的地气相互作用综合观测实验，也是目前国际上野外连续观测时间最长的一次陆面过程实验，取得了欧亚大陆腹地典型干旱地区黑河流域沙漠、戈壁、绿洲等不同下垫面上的太阳辐射、大气边界层气象资料和绿洲生物气象资料，并收集了该地区常规气象和水文资料，为干旱地区陆面过程的理论研究奠定了观测实验基础。
\n\n黑河实验数据库（HDB）（陶泽宏和左洪超，1994a）全面收集和系统整编了黑河实验野外观测资料。在该数据库中，所有观测资料按观测性质和目的分为三类：
\n\n第一类：正常观测期（FOP）资料。它包括：（1）5个微气象站和5个自动气象站观测资料；（2）4个井站观测地下水位资料；（3）吹沙、沙尘分布及臭氧观测资料；（4）3个高空气象站、3个地面气象站和4个水文站和一些雨量站及井下水位站常规观测资料。
\n\n第二类：加强观测期（IOP）资料。它包括：各个加强期（PlOP，IOP-1，lOP-2，IOP-3，IOP-4）中湍流、系留气球、声雷达（Sodar）、激光雷达（Lidar），土壤含水量及成份的观测资料。
\n\n第三类：特殊观测期资料，它包括：生物气象观测（BOP），干旱地区降水机制观测（IOP-R），湍流对比观测（IOP-C）和远离绿洲的沙漠补充观测资料（IOP-DA）以及沙样实验的观测资料。更详细的信息请参考HEIFE数据库使用手册（陶泽宏 等，1994b）。

", "ds_ref_way": "", "ds_abstract": "HEIFE is a comprehensive observation experiment of the interaction between the earth and the atmosphere in a 70km × 90km experimental area in the middle part of Heihe River Basin in the Hexi corridor. It is also the longest continuous observation experiment of land surface process outside the field in the world. It has obtained a typical Eurasia hinterland The solar radiation, atmospheric boundary layer meteorological data and oasis bio meteorological data on different underlying surfaces of desert, Gobi and oasis in Heihe River Basin of arid area are collected, and the conventional meteorological and hydrological data in this area are collected, which lays a foundation for the theoretical study of land surface process in arid area.
\nHDB (Tao Zehong and Zuo Hongchao, 1994a) collected and systematically compiled the field observation data of Heihe experiment. In the database, all observation data are divided into three categories according to the nature and purpose of observation:
\nThe first type: FOP data. It includes: (1) observation data of 5 micro meteorological stations and 5 automatic meteorological stations; (2) observation data of groundwater level of 4 well stations; (3) observation data of sand blowing, dust distribution and ozone; (4) routine observation data of 3 high altitude meteorological stations, 3 surface meteorological stations, 4 hydrological stations, some rainfall stations and underground water level stations.
\nThe second category: enhanced observation period (IOP) data. It includes: observation data of turbulence, tethered balloon, SODAR, lidar, soil water content and composition in each strengthening period (plop, iop-1, lop-2, iop-3, iop-4).
\nThe third category: special observation period data, which includes: biological meteorological observation (BOP), precipitation mechanism observation in arid areas (iop-r), turbulence contrast observation (iop-c), desert supplement observation data far away from Oasis (iop-da) and sand sample experiment observation data. For more details, please refer to the HEIFE database user manual (Tao Zehong et al., 1994b).
