Dataset of Heihe River Basin field experiment (1990-1992)

Interaction "heihe region in field observation experiment (HEIFE)", is in the heihe river basin in hexi corridor in the middle of a 70 km by 90 km range of experimental zone for the center with water and heat exchange of a very comprehensive experiment, the interaction is the current international field the longest continuous observation on the land surface process experiment, has obtained the Eurasia hinterland typical in heihe river basin, gobi desert and oasis in arid regions different underlaying surface, such as solar radiation, atmospheric boundary layer meteorological data and oasis of meteorological data, and collect the conventional meteorological and hydrological data in the region,It has laid the foundation of observation experiment for theoretical study of land surface processes in arid areas.The heihe experimental database (HDB) (tao zehong and zuo hongchao, 1994a) comprehensively collected and systematically integrated 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:Category 1: normal observation period (FOP) data.It includes :(1) observation data of 5 micrometeorological stations and 5 automatic meteorological stations;(2) groundwater level data observed at four well stations;(3) distribution of blowing sand and dust and ozone observation data;(4) conventional observation data of 3 upper-air weather stations, 3 surface weather stations, 4 hydrology stations, some rain measuring stations and downhole water stations. The second category: enhanced observation period (IOP) data.It includes: observations of turbulence, tethered balloons, Sodar, Lidar, soil moisture content and composition during each strengthening period (PlOP, IOP-1, lop-2, IOP-3, IOP-4).The third category is special observation period data, which includes: biological meteorological observation (BOP), precipitation mechanism observation (iop-r) in arid areas, turbulence contrast observation (iop-c), supplementary observation data of deserts far from the oasis (iop-da) and observation data of sand sample experiment.Please refer to HEIFE database user manual for more detailed information (tao zehong et al., 1994b).

本数据集描述了位于河西走廊黑河流域的‘黑河区域地表过程观测实验（HEIFE）’。该实验区域覆盖了一个70公里乘以90公里的实验带中心，其中包含一个关于水热交换的全面实验。该观测实验是当前国际上对地表过程进行的最长连续观测，它收集了欧亚大陆腹地黑河流域、戈壁沙漠以及干旱地区绿洲等地表下不同覆盖层（如太阳辐射、大气边界层气象数据、绿洲气象数据）的典型数据。此外，还收集了该区域的常规气象和水文数据，为干旱地区地表过程的理论研究奠定了观测实验基础。黑河实验数据库（HDB）（陶泽中、左红超，1994a）全面系统地收集和整合了黑河实验的观测数据。在数据库中，所有观测数据根据观测性质和目的分为三类：第一类为常规观测期（FOP）数据，包括：（1）5个微气象站和5个自动气象站的观测数据；（2）四个井站观测的地下水位数据；（3）风沙和臭氧观测数据；（4）3个高空气象站、3个地面气象站、4个水文站、一些雨量测量站和地下水位观测站的常规观测数据。第二类为增强观测期（IOP）数据，包括：在每个增强期（PlOP、IOP-1、IOP-2、IOP-3、IOP-4）进行的湍流、系留气球、Sodar、Lidar、土壤水分含量和组成观测。第三类为特殊观测期数据，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）、远离绿洲的沙漠补充观测数据（IOP-da）和沙样实验观测数据。更详细的信息请参阅HEIFE数据库用户手册（陶泽中等，1994b）。
