A novel cross-satellite based assessment of the spatio-temporal development of a cyanobacterial harmful algal bloom.

•Produced a phenological analysis of the 2016 cyanobacterial bloom in Utah Lake.•Developed a robust CyanoHAB monitoring and prediction method using LS8 and Sen2A.•Analysis involved a novel way to cross-calibrate a chlorophyll-a model across satellites.•Reviewed the need for frequent, recurring monitoring techniques for these bloom events.
