TERENO (Northeast), Soil moisture station Jarmen BF2, Germany

The Jarmen BF2 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 Jarmen BF2 was installed in 2012. It is located on the edge of two field, with sensors A below the southern field and sensors B to the north. 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 and ScemeSpadeSoilMoisture_Spade_6The 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.2018.028 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.

Jarmen BF2土壤湿度站（Jarmen BF2 soil moisture station）属于农业气象试验场的组成部分，旨在为遥感与环境建模领域的算法开发提供环境数据，研究重点聚焦于土壤湿度与蒸散发（evapotranspiration）。该场地被广泛应用于农业土地管理实践中遥感数据集成的实地测试。德国宇航中心（DLR）于1999年搭建了首批测量基础设施，2011年及后续随着该场地加入TERENO-NE观测台站，监测设备得到了扩容升级。Jarmen BF2土壤湿度站于2012年正式投用，其选址位于两块农田的交界处，传感器A布设于南侧农田下方，传感器B设于北侧区域。该站点配备的传感器可采集以下变量：ScemeSpadeSoilMoisture_Spade_1、ScemeSpadeSoilMoisture_Spade_2、ScemeSpadeSoilMoisture_Spade_3、ScemeSpadeSoilMoisture_Spade_4、ScemeSpadeSoilMoisture_Spade_5及ScemeSpadeSoilMoisture_Spade_6。本数据集当前版本为1.1，相较于此前版本新增了两年的观测数据（from-year至year），并对数据标记（data flags）进行了修订。所有变更的详细说明可查阅站点说明文件。1.0版本可通过数据下载链接的"previous_versions"子文件夹获取。该数据集的首个版本以http://doi.org/10.5880/TERENO.GFZ.2018.028发布，仅包含实测数据；2.0版本则新增了各实测值的质量标记与扩展元数据。本数据集亦可通过TERENO数据发现门户（TERENO Data Discovery Portal）获取。数据集文件将每年更新一次，以纳入站点新采集的观测数据，元数据文件亦会同步更新。若有新增监测变量，将按需追加新的数据列。若因数据处理流程变更导致历史数据调整，将通过新的DOI发布该数据集的新版本。新观测数据将延迟数月后加入，以确保人工参与质量管控流程。本数据集的数据处理采用DMRP版本0.5.12，元数据处理采用DMETA版本0.3.17。
