Abstract/Description: A novel technique to interpolate satellite ocean colour data has been developed and calibrated in the framework of the European MyOcean2 project and successively implemented within the Copernicus Marine Environment Monitoring Service (CMEMS) specifically for the Mediterranean Sea products. The methodology is based on the Data Interpolating Empirical Orthogonal Functions technique, which interpolates data voids from Empirical Orthogonal Function (EOF) modes iteratively estimated as characteristic spatial patterns. Here, this method is extended to take into account the temporal correlation between the observations. A higher-dimensional approach is followed by using a temporal sequence of daily images to build the state vector and thus the observation matrix used to compute the EOFs. An ad-hoc smoothing procedure is also applied to resulting 2-dimensional fields to filter out spurious signals and provide consistent spatial reconstructions. Several tests are performed on a dataset at 4 km resolution to calibrate the technique and to assess, among other issues, the most convenient number of images to be included in the state vector. The final CMEMS product at 1 km resolution is then validated with the independent chlorophyll data collected during dedicated oceanographic surveys between 1997 and 2015 across the entire Mediterranean basin.
