2013 was bloomcast’s 2nd year in production 2012: ● Cloud fraction interpolation problem ● Bloom date agreed with satellite and cruise chlorophyll data 2013: ● New Cloud fraction interpolation algorithm (thanks to Requests and NumPy) ● Bloom date agreed with satellite and chlorophyll data from an instrumented ferry
