Stream Temperature - Parkland (PKLD) Water year 2007-2008

Metadata for BES site - Stream Temperature: Parkland (PKLD): In the Baltimore urban long-term ecological research (LTER) project, (Baltimore Ecosystem Study, BES) we use the watershed approach to evaluate integrated ecosystem function. The LTER research is centered on the Gwynns Falls watershed, a 17,150 ha catchment that traverses a gradient from the urban core of Baltimore, through older urban residential (1900 - 1950) and suburban (1950- 1980) zones, rapidly suburbanizing areas and a rural/suburban fringe. Stream temperature is continuously measured throughout the Gwynns Falls watershed along with supplemental sites around Baltimore County/City. A total of 22 sites contain sensors (HOBO Pro v2 Water Temperature Data Logger - U22-001) that take an instantaneous temperature reading every 2 minutes. These data are downloaded on a monthly basis. This dataset is for Parkland, a segment of stream that is headwater to the Jennifer Branch, Harford Hills (JBHH) site. It drains an area of 19 ha with 13.5% forested and 27% impervious land cover. Watershed information was taken from delineations created with USGS StreamStats at http://water.usgs.gov/osw/streamstats/maryland.html Purpose: Long-term monitoring of stream temperature in a suburban watershed.

巴尔的摩生态系统研究（Baltimore Ecosystem Study, BES）场地元数据——溪流温度：帕克兰（PKLD）
在巴尔的摩城市长期生态研究（Long-Term Ecological Research, LTER）项目——巴尔的摩生态系统研究（BES）中，我们采用流域方法评估综合生态系统功能。该LTER研究以格温斯福尔斯流域为核心，这片面积达17150公顷的集水区梯度覆盖巴尔的摩城市核心区、1900-1950年建成的老旧城市居住区、1950-1980年建成的郊区地带、快速郊区化区域及城乡结合部。
研究团队对格温斯福尔斯流域全域，以及巴尔的摩县/市周边的补充监测点位开展溪流温度连续监测。共计22个监测点位安装了HOBO Pro v2型水温数据记录仪（型号U22-001），每2分钟记录一次瞬时温度读数，上述数据每月进行一次下载整理。
本数据集对应帕克兰溪流段，它是哈福德山（JBHH）站点詹妮弗支流的源头溪流段。该溪流流域面积为19公顷，林地占比13.5%，不透水地表占比27%。流域边界信息源自美国地质调查局（United States Geological Survey, USGS）StreamStats工具生成的划界结果，相关网址为：http://water.usgs.gov/osw/streamstats/maryland.html
数据集用途：针对郊区流域开展溪流温度长期监测。
