For the FloodNet data collection page, please follow this link. Data presented here were collected by the FloodNet project, which is a collaboration between researchers at academic institutions (New York University and the City University of New York) and NYC government agencies (NYC Department of Environmental Protection, Mayor's Office of Climate & Environmental Justice, Office of Technology & Innovation), working with NYC residents. Data on flood water depth were collected by FloodNet sensors in one minute intervals, then analyzed to develop the flood event summary statistics presented here. A flood event is defined as a series of water depth measurements greater than 10 mm; all measured flood events presented here have undergone QC by a member of the FloodNet team. See attached data description document for more details on data collection, analysis & the publication to cite if using the data or including it in any publication or public presentation.
