Overview of the loadeR.ECOMS package
Since the R language has been adopted for some key tasks in the EUPORIAS and SPECS projects (including the development of comprehensive validation and statistical-downscaling packages), loadeR.ECOMS is envisaged as a user-friendly, R-based interface to the ECOMS User Data Gateway, enabling authentication and remote access to the different datasets (seasonal forecasting, observations, reanalysis) currently available (take a look at the available datasets and variables). Moreover, loadeR.ECOMS implements data homogenization (a single vocabulary) and time filtering/aggregation in a transparent way for the user, and it is seamlessly integrated with the downscaleR package for downscaling/bias correction and other climate data post-processing.
loadeR.ECOMS extends the loadeR package, which in turn relies on the powerful capabilities of the Unidata's netCDF Java library.
The following panels show an illustrative use of ECOMS-UDG to obtain the minimum DJF temperature DJF bias for System4 hindcast (one-month lead time) over Europe. WFDEI is used as reference.
