E.coli and fluorescence of the Tijuana River, 2022-2023

Fluorescence-based sensors of tryptophan (TRP) and chromophoric dissolved organic matter (CDOM) can provide real-time information on water quality. This resource includes data on water quality of the Tijuana River at the International Boundary and Water Commission stream gage for the years 2022 and 2023, including TRP, CDOM, and standard parameters including temperature, conductivity, and turbidity. TRP and CDOM were measured continuously with an in situ sumbersible sonde (Manta) and in the laboratory using a Horiba Aqualog fluorometer. Additional files include the results of wastewater addition experiments conducted in the laboratory, using both the Manta and Aqualog to measure TRP and CDOM. The README file contains details.

基于荧光技术的色氨酸（tryptophan, TRP）与有色溶解有机物（chromophoric dissolved organic matter, CDOM）传感器可提供实时水质监测信息。本数据集涵盖2022至2023年蒂华纳河国际边界与水委员会（International Boundary and Water Commission）水文监测站的水质数据，包含TRP、CDOM以及温度、电导率、浊度等标准水质参数。其中TRP与CDOM的监测采用两种方案：一是通过原位水下探头（in situ submersible sonde，Manta型）开展连续原位监测，二是在实验室中使用Horiba Aqualog荧光分光光度计进行测定。附加文件包含实验室开展的污水添加实验结果，实验过程中同步使用Manta探头与Aqualog荧光仪完成TRP与CDOM的测定。详细说明请参见README文件。
