Mediterranean Sea - Po River - DIVAnd 4D seasonal analysis of Water body chlorophyll-a 1980/2019 v2021

Water body chlorophyll-a - Seasonal Climatology for Po River for the period 1980-2019 on the domain: Lon E12.0-14.0 deg.E, Lat N44.0-46.00 deg.N.

Data Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network.

Description of DIVA analysis: The computation was done with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.4, using GEBCO 30sec topography for the spatial connectivity of water masses. A relative correlation length used based on topography gradients and the horizontal correlation length varies from 25 km to 12.5 km. The vertical correlation length (in meters) is: [4.,4.,4.,4.,4.,10.,10.,10.,10.,20.,20.,20.,20.,20.]. Depth range: [0., 2., 4., 6., 8., 10., 15., 20., 25., 30., 40., 50., 60., 70.]. Units: mg/m3.

The horizontal resolution of the produced DIVAnd maps grids is dx=dy=0.009 degrees (around 975m and 708m accordingly).

Additional analysis parameters: The error variance (epsilon2) was set equal to 1. Data weight was reduced near the coasts. Data weighting was applied with the following threshold values: lon=0.03, lat=0.03, depth=2. Threshold value for log transformation=200.

Seasons definition: Winter=Jan-Mar, Spring=Apr-Jun, Summer=Jul-Sep, Autumn=Oct-Dec.
