Black Sea, Danube Delta, DIVAnd 4D seasonal analysis of Water body silicate 1970/2022 v2025 [lat][lon], 0.01deg

Horizontal correlation length of 47.73km and vertical correlation length of 45m were applied. The horizontal resolution of the produced DIVAnd maps grids is 0.01 degrees. The vertical resolution is 17 depth levels: 0.0, 2.0, 4.0, 6.0, 8.0, 10.0, 15.0, 20.0, 25.0, 30.0, 40.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0 m.

The error variance (epsilon2): 1 An anamorphosis transformation was applied to the data: threshold value=200. The mean value was used as background analysis field. Quality control of the observations was applied using the interpolated field: QCMETHOD=3 and visual inspection (Observations with residuals outside the minimum and maximum values of the 99% quantile were discarded from the analysis after thoroughly visual inspection).
