Chlorophyll-A algorithm question
Yes, it is arbitrary, but it is also an order of magnitude larger than any value we would have any expectation to be real (and thus quite extreme).The data set used to generate the algorithm has very few concentrations higher than 50mg/m3, and none at the CHLWARN flag max of 100 mg/m3.So, if the alg...

Ajit,
I can't make it not work on my up-to-date MacOS Sierra...

seadas-7.4 GUI java exception
