Impact/Purpose:
The Cyanobacteria Assessment Network's mission is to support the environmental management and public use of U.S. lakes and reservoirs by providing a capability to detect and quantify algal blooms and related water quality using satellite data records.
Description:
The Cyanobacteria Assessment Network (CyAN) is a multi-agency (NASA, USGS, NOAA, and EPA) project and its mission supports the environmental management and public use of U.S. lakes and reservoirs by providing a capability of detecting and quantifying algal blooms using satellite data records and disseminating this information through CyAN’s API used in a mobile application developed and hosted by EPA. The app provides water quality managers with a user-friendly platform that reduces the complexities associated with accessing satellite data to allow fast, efficient, initial assessments across lakes and reservoirs. Data from the European Space Agency Copernicus Sentinel-3 satellite Ocean and Land Colour Instruments (OLCI) are used in near real-time to make initial water quality assessments and quickly alert managers to potential problems and emerging threats related to cyanobacteria. Data for 2019 OLCI-derived cyano imagery is available through the API. The cyano data covers the continental U.S. at 300m resolution and represents the weekly maximum value cyanobacteria response of 2,370 resolvable lakes and reservoirs. The imagery is updated on a weekly schedule to provide a near real-time view of cyano water quality at user-selected areas of interest. This makes the latest data available via the API by COB the following Monday. The CyAN API employs REST style API calls using HTTPS protocol supported by the cyan.epa.gov server hosted in the EPA’s National Computer Center. The path to the API endpoints is /cyan/cyano/ and supports requests for three types of resources; /location/images, /location/data, and /notifications. All publicly available calls are of method type GET. Response data format is of type json; the only key:value specification in the request header is “Accept:application/json”.
