BOREAS HYD-01 VOLUMETRIC SOIL MOISTURE DATA

The BOREAS HYD-01 team made measurements of volumetric soil moisture at the SSA and NSA tower flux sites in 1994 and at selected tower flux sites in 1995-97. Different methods were used to collect these measurements, including neutron probe and manual and automated TDR. In 1994, the measurements were made every other day at the NSA-OJP, NSA-YJP, NSA-OBS, NSA-Fen, SSA-OJP, SSA-YJP, SSA-Fen, SSA-YA, and SSA-OBS sites. In 1995-97, when automated equipment was deployed at NSA-OJP, NSA-YJP, NSA-OBS, SSA-OBS, and SSA-OA, the measurements were made as often as every hour.BOREAS HYD-01研究团队于1994年在南部研究区（SSA）与北部研究区（NSA）的通量塔站点开展体积土壤含水量（volumetric soil moisture）测量，并于1995年至1997年在选定的通量塔站点开展同类测量。本次测量采用了多种数据采集手段，包括中子仪（neutron probe）、手动时域反射仪与自动时域反射仪（TDR）。1994年，研究人员在NSA-OJP、NSA-YJP、NSA-OBS、NSA-Fen、SSA-OJP、SSA-YJP、SSA-Fen、SSA-YA及SSA-OBS站点每隔一日进行一次测量。1995年至1997年，随着NSA-OJP、NSA-YJP、NSA-OBS、SSA-OBS及SSA-OA站点部署了自动化观测设备，测量频率提升至每小时一次。
