Neural Networks Technique for Filling Gaps in Satellite Measurements: Application to Ocean Color Observations

Figure 6

Three-year time series of global mean NN chlorophyll-a bias, referenced to VIIRS observations (VIIRS-NN values): black curves represent results from the full data set; red curves represent results when Chl-a values exceeding 1.0 mg/m³ have been removed (less than 1% of data removed); solid lines show the ensemble mean bias and dashed lines depict the mean bias produced by an individual NN. The validation period (2014) is indicated.
