Rainfall, throughfall and stemflow for beech and ash stands in temperate English deciduous woodlands

Water quality data produced from rainfall, throughfall and stemflow samples collected within a beech stand at Black Wood in Hampshire, and an ash stand at Old Pond Close in Northamptonshire. Two studies were carried out in the early 1990s to examine water quality in relation to hydrological and pollution changes. Chemical analysis involved a combination of electrometric (pH), inductively-coupled plasma emission spectroscopy (most major, minor and trace elements), atomic absorption spectroscopy (potassium), ion chromatography (major anions and fluorine) and colourimetry (ammonium and silicon).本数据集包含采集自英国汉普郡布莱克伍德山毛榉林分与北安普敦郡老塘围场白蜡林分的降雨、林冠穿透水（throughfall）及树干茎流（stemflow）样本所生成的水质数据。两项于20世纪90年代初开展的研究，旨在探究水质与水文及污染变化之间的关联。本次研究所采用的化学分析手段包括：电位法（pH值测定）、电感耦合等离子体发射光谱法（inductively-coupled plasma emission spectroscopy，用于多数常量、微量及痕量元素分析）、原子吸收光谱法（atomic absorption spectroscopy，钾元素测定）、离子色谱法（ion chromatography，常量阴离子与氟元素分析）以及比色法（colourimetry，铵离子与硅元素分析）。
