Hydrometeorological observations of small watersheds of the northeast Pacific coastal temperate rainforest (NPCTR) of North America are important to understand land to ocean ecological connections and to provide the scientific basis for regional environmental management decisions. The Hakai Institute operates a densely networked and long-term hydrometeorological monitoring observatory that fills a spatial data gap in the remote and sparsely gauged outer coast of the NPCTR. Here we present the first 5 water years (October 2013–October 2019) of high-resolution streamflow and weather data from seven small (< 13 km²) coastal watersheds. Measuring rainfall and streamflow in remote and topographically complex rainforest environments is challenging; hence, advanced and novel automated measurement methods were used. These methods, specifically for streamflow measurement, allowed us to quantify uncertainty and identify key sources of error, which varied by gauging location. Average yearly rainfall was 3267 mm, resulting in 2317 mm of runoff and 0.1087 km³ of freshwater exports from all seven watersheds per year. However, rainfall and runoff were highly variable, depending on the location and elevation. The seven watersheds have rainfall-dominated (pluvial) streamflow regimes, streamflow responses are rapid, and most water exports are driven by high-intensity fall and winter storm events. The complete hourly and 5 min interval datasets can be accessed at https://doi.org/10.21966/J99C-9C14 (Korver et al., 2021), and accompanying watershed delineations with metrics can be found at https://doi.org/10.21966/1.15311 (Gonzalez Arriola et al., 2015).

加拿大东北太平洋沿海温带雨林七个小沿海流域的高分辨率水流和天气数据（2013-2019 年）

北美东北太平洋沿岸温带雨林（NPCTR）小流域的水文气象观测对于了解陆海生态联系和为区域环境管理决策提供科学依据具有重要意义。Hakai 研究所运营着一个密集网络和长期水文气象监测观测站，填补了 NPCTR 偏远和稀疏测量的外海岸的空间数据空白。在这里，我们展示了来自七个小型（<  13 km ²) 沿海流域。在偏远和地形复杂的热带雨林环境中测量降雨和水流具有挑战性；因此，使用了先进和新颖的自动测量方法。这些方法，特别是用于流量测量的方法，使我们能够量化不确定性并确定主要误差源，这些误差源因测量位置而异。年平均降雨量为 3267 毫米，导致径流 2317 毫米和 0.1087 公里³每年所有七个流域的淡水出口量。然而，降雨和径流变化很大，具体取决于位置和海拔。七个流域具有以降雨为主的（雨洪）河流流态，河流流量响应迅速，并且大多数水出口是由高强度的秋季和冬季风暴事件驱动的。完整的每小时和 5 分钟间隔数据集可在 https://doi.org/10.21966/J99C-9C14（Korver 等人，2021 年）访问，随附的带指标的流域划分可在 https://doi 找到。 org/10.21966/1.15311（Gonzalez Arriola 等人，2015 年）。
