“…Satellite sensor technology is currently (2023) undergoing rapid development that is enabling advanced spectral resolution, increased overpass frequency, imaging across a range of spatial scales, interoperability and harmonization of satellite sensors, and high performance cloud platforms that facilitate advancements in geoprocessing and spatial data science. 27,36,72 The chlorophyll-a concentration estimates described herein are limited to the in-situ matches between water-quality data and satellite imagery obtained during the study period. Because of the performance uncertainties described herein, chlorophyll-a concentrations estimated from satellite imagery would benefit from additional field observations for validation purposes.…”

“…Recently, Legleiter et al (2022) combined spectral imaging from the laboratory with satellite data to resolve bloom‐forming cyanobacteria. They obtained reflectance spectra of different cyanobacteria species in the laboratory with a spectral imager attached to a microscope and used those as spectral endmembers to resolve to taxa level using data from satellite images.…”

“…Satellite-derived information on the land cover type, temperature, humidity, spectral data, and other environmental variables can be used in the surveillance of algal blooms in fresh, brackish, and salt water [ 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 ]. Formal surveillance programs are already in place within the United States, such as the Center for Disease Control’s (CDC) One Health Harmful Algal Bloom System (OHHABS) and the Environment Protection Agency’s (EPA) Cyanobacteria Assessment Network (CyAN).…”
