High-frequency water quality data for water temperature, dissolved oxygen, specific conductivity, pH, phycocyanin fluorescence and chlorophyll a fluorescence at Lake Lillinonah, Connecticut, USA, 2018-current.

Since 2011, an instrumented buoy maintained by Friends of the Lake (FOTL, friendsofthelake.org) and Fairfield University has been deployed on Lake Lillinonah (Connecticut, USA) during the summer months to collect high-frequency water quality data. The buoy is deployed early each summer and remains in the lake until late October. Since 2018, the instrumented buoy has been equipped with a YSI EXO2 sonde at a depth of 1 meter. The YSI EXO2 collects water temperature, dissolved oxygen, specific conductivity, pH, chlorophyll a fluorescence and phycocyanin fluorescence data. Additionally, the instrumented buoy is equipped with an In-Situ RDO sensor which collects water temperature and dissolved oxygen readings at a depth of 15 meters. Included in this data package are datasets containing 15-minute data as well as daily averages from both sensors from 2018 to present. Prior to 2018, the instrumented buoy was equipped with a YSI 6600 sonde, which collected data on the same variables (2011-2017). Data from the YSI 6600 sonde, as well as data from the In-Situ RDO sensor during the same period, are available in the EDI data package EDI559. Additionally, the instrumented buoy at Lake Lillinonah is equipped with a water temperature thermistor chain sensor. These data can be found in data packages EDI557 (2011-2015) and EDI558 (2018-current).

自2011年起，由湖泊之友（Friends of the Lake, FOTL, friendsofthelake.org）与费尔菲尔德大学共同维护的水质监测浮标，于每年夏季部署在美国康涅狄格州的利洛纳湖（Lake Lillinonah），以采集高频水质数据。该浮标于每年夏季初期布设，直至10月末撤离。

自2018年起，该水质监测浮标搭载了安装于1米水深处的YSI EXO2多参数水质探头（YSI EXO2 sonde），可采集水温、溶解氧、比电导率、pH值、叶绿素a荧光以及藻蓝蛋白荧光数据。此外，该浮标还配备了In-Situ RDO传感器（In-Situ RDO sensor），可在15米水深处采集水温和溶解氧数据。本数据包涵盖2018年至今两台传感器的15分钟级数据及日均值数据集。

2018年之前，该浮标搭载的是YSI 6600多参数水质探头（YSI 6600 sonde），可采集相同参数的水质数据（2011-2017年）。YSI 6600多参数水质探头同期数据，以及同时间段的In-Situ RDO传感器数据，均可在EDI数据包EDI559中获取。

此外，利洛纳湖的水质监测浮标还配备了水温热敏电阻链传感器。相关数据可分别在数据包EDI557（2011-2015年）与EDI558（2018年至今）中获取。
