The Chicago Park District maintains weather sensors at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/id/qmqz-2xku for a dataset with similar measurements on the lake water, itself. The sensor locations are listed at https://data.cityofchicago.org/d/g3ip-u8rb.

This dataset is historical-only. -- Results from a 2017-2018 project of City-installed sensors measuring water runoff from streets and sidewalks. These data can be used to measure the impact of sustainable green infrastructure on flooding. These sensors also captured weather data.

Each row corresponds to a sensor measurement at a specific time and location. Each row is a different sensor, which can be determined from the "Measurement Title" column. The value for each measurement is always numeric and available in the "Measurement Value" column. The corresponding unit of measurement is in the "Units" column. Data may be missing at times due to sensors not being available.
