An EPA, NASA, NOAA, and USGS Project

CyAN is a multi-agency project among EPA, the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and the United States Geological Survey (USGS) to develop an early warning indicator system to detect algal blooms in U.S. freshwater systems. This research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health.

Project Overview

The mission of the CyAN's project is to support the environmental management and public use of U.S. lakes and estuaries by providing a capability of detecting and quantifying algal blooms and related water quality using satellite data records.

Project Timeline

The CyAN project officially started October 1, 2015. It provided continental U.S. coverage using the MERIS archive from 2002-2012 in Fiscal Year 2017. Weekly composites of the European Space Agency Copernicus Sentinel-3 OLCI sensor data are now available to collaborators for initial review and validation. Landsat surface water temperature product is now publicly available through USGS EROS.

Project Components and Fiscal Year Updates

Validation

In situ validation data will primarily come from our federal and state collaborators. Sources of data will include, but are not limited to, federal, state, and local government agencies, universities, private research groups, and published peer-reviewed journals. Minimum data reporting requirements include sample station identification, cyanobacteria counts, abundance, or phycocyanin pigment concentration, latitude, longitude, depth, and date. Additional information that are not required but are considered beneficial include chlorophyll  a  concentration (especially), temperature, secchi depth, turbidity, and other available water quality measures. Data sets will undergo quality review by confirming that all methods used were documented and widely accepted.
