Sub-hourly water temperature data collected by UNBC's northern hydrometeorology group (NHG) across the Nechako Watershed, 2019-2021

This is a dataset of water temperature time series collected at 15 minute intervals at 24 sites across the Nechako Watershed. Data are provided in comma-delimited format with one file for each site. Each file name identifies the site location. The first column contains the date/time (UTC) in the format MM/DD/YEAR HH:MM. The second column contains the corresponding water temperature in degrees Celsius to two decimals. The third column contains a recommended flag for data quality, with "P" representing a "pass", "F" denoting a "fail", and "B" denoting "backwater conditions" with the likely presence of ice and below freezing temperatures. Additional issues encountered at specific sites are identified in the attached "read me" file along with basic metadata (site coordinates, elevation and period of record). A map of the sites is also attached to depict their locations across the Nechako Watershed.本数据集为内查科流域（Nechako Watershed）内24个监测站点采集的水温时间序列数据，采样间隔为15分钟。数据以逗号分隔格式存储，每个站点对应一个独立数据文件，文件名可直接标识对应站点的位置。每个数据文件的第一列为采用MM/DD/YEAR HH:MM格式记录的协调世界时（UTC）日期与时间；第二列为对应时刻的水温数据，保留两位小数，单位为摄氏度；第三列为推荐的数据质量标记，其中“P”代表数据通过校验，“F”代表数据未通过校验，“B”代表回水状态，此时水域大概率存在冰层且水温低于冰点。附带的"read me"文件中记录了各站点遇到的额外异常问题，同时包含基础元数据（站点坐标、海拔及记录时段）。此外还附带了站点分布图，用于展示各监测点在内查科流域内的具体位置。
