TERENO (Northeast), Soil moisture station Heydenhof BF1, Germany

The Heydenhof BF1 soil moisture station is part of an agrometeorological test site and aims at supplying environmental data for algorithm development in remote sensing and environmental modelling, with a focus on soil moisture and evapotranspiration.The site is intensively used for practical tests of remote sensing data integration in agricultural land management practices. First measurement infrastructure was installed by DLR in 1999 and instrumentation was intensified in 2011 and later as the site became part of the TERENO-NE observatory.The soil moisture station station Heydenhof BF1 was installed in 2012. It is located on the southern edge of a hedge row with sensors south of the station and below the field. The station is equipped with sensor for measuring the following variables: ScemeSpadeSoilMoisture_Spade_1, ScemeSpadeSoilMoisture_Spade_2, ScemeSpadeSoilMoisture_Spade_3, ScemeSpadeSoilMoisture_Spade_4, ScemeSpadeSoilMoisture_Spade_5, ScemeSpadeSoilMoisture_Spade_6 and ScemeSpadeSoilMoisture_Spade_2_TemperatureThe current version of this dataset is 1.1. This version includes two additional years of data (from-year to-year)and a revised version of the data flags. A detailed overview on all changes is provided in the station description file. The version 1.0 is available in the 'previous_versions' subfolder via the Data Download link. A first version of this data was provided under http://doi.org/10.5880/TERENO.GFZ.2018.025 containing the measured data and Version 2.0 contains additionally the quality flags for each measured value and extended metadata.The dataset is also available through the TERENO Data Discovery Portal. The datafile will be extended once per year as more data is acquired at the stations and the metadatafile will be updated. New columns for new variables will be added as necessary. In case of changes in dta processing, which will result in changes of historical data, an new Version of this dataset will be published using a new doi. New data will be added after a delay of several months to allow manual interference with the quality control process.Data processing was done using DMRP version: 0.5.12. Metadataprocessing was done using DMETA version: 0.3.17.

Heydenhof BF1土壤湿度站属于农业气象试验场，旨在为遥感与环境建模领域的算法研发提供环境数据，核心聚焦于土壤湿度与蒸散发(evapotranspiration)。
该试验场被广泛用于农业土地管理实践中的遥感数据融合实地测试。
其首批测量基础设施于1999年由德国宇航中心(DLR)搭建；2011年及后续，随着该场地加入TERENO-NE观测台，站内观测设备得到了扩容升级。
Heydenhof BF1土壤湿度站于2012年正式搭建，坐落于树篱带的南侧，传感器布设于站点南侧的农田下方。
该站点配备了用于测量以下变量的传感器：ScemeSpadeSoilMoisture_Spade_1、ScemeSpadeSoilMoisture_Spade_2、ScemeSpadeSoilMoisture_Spade_3、ScemeSpadeSoilMoisture_Spade_4、ScemeSpadeSoilMoisture_Spade_5、ScemeSpadeSoilMoisture_Spade_6以及ScemeSpadeSoilMoisture_Spade_2_Temperature。
本数据集当前版本为1.1，新增了两年的观测数据（原文未明确标注具体年份范围），并对数据标记(data flags)进行了修订。
所有修订细节的完整说明已收录于站点说明文件中。
1.0版本可通过数据下载链接在「previous_versions」子文件夹中获取。
该数据集的首个版本以DOI：10.5880/TERENO.GFZ.2018.025公开，仅包含实测数据；而2.0版本则额外新增了各实测值的质量标记与扩展元数据(metadata)。
该数据集也可通过TERENO数据发现门户获取。
随着站点获取更多观测数据，数据文件将每年更新一次，元数据文件也会同步更新。
若有新增变量需求，将同步新增对应的数据列。
若因数据处理流程变更导致历史数据发生调整，本数据集将发布新版本并分配新的DOI标识。
新增数据将延迟数月后发布，以便开展人工质量管控与质控流程。
本数据集的数据处理采用DMRP版本0.5.12完成，元数据处理则采用DMETA版本0.3.17完成。
