coastDat-2 Hydrodynamic Model TRIM-NP Principal Component Analysis Residual Currents

Project: coastDat-2 - CoastDat-2 (http://www.coastdat.de/about_us/index.php) comprises a compilation of coastal analyses (that is hindcasts and reconstructions) and scenarios for the future obtained from numerical models. The atmospheric part of the dataset is simulatated using the COSMO-CLM (http://www.clm-community.eu). The objective is to provide a consistent meteo-marine data set.
Summary: Simulated 2D residual velocity fields in the inner German Bight were
subjected to Principal Component Analysis (PCA). Residual currents
were obtained from coastDat2 barotropic 2D simulations with the
hydrodynamic model TRIM-NP V2.1.22 in barotropic 2D mode on a Cartesian grid (1.6km spatial resolution)
stored on an hourly basis for the years 1948 - 2012
(doi:10.1594/WDCC/coastDat-2_TRIM-NP-2d) and later extended until
August 2015.
The present analysis refers to the period Jan 1958 - Aug 2015. The spatial
domain considered is the region to the east of 6 degrees east and to
the south of 55.6 degrees north. All grid nodes with a bathymetry of
less than 10m were excluded.

Residual velocities were calculated in two different ways:
1.) as 25h means,
2.) as monthly means.
