Tools and algorithms for drone and satellite based ocean color science

Currently in the process of implementing a few of the NASA Ocean Color team's chlorophyll retrieval algorithms from https://oceancolor.gsfc.nasa.gov/atbd/chlor_a/. The goal is to make these algorithms more easily understandable and to allow fine-tuning for sensors that differ from the primary NASA ocean observing satellites, particularly for drone-based multispectral sensors. This is all done right now using the NASA bio-Optical Marine Algorithm Dataset (NOMAD) available at https://seabass.gsfc.nasa.gov/wiki/NOMAD.

Currently implemented algorithms:

Application examples

  • applying the OCx algorithm on Landsat 8's Provisional Aquatic Reflectance product - code
