Copulas for integrating weather and land information in space and time

A complete process description considers both spatio-temporal dependencies and associations between those variables. Describing the dependencies is challenging because natural phenomena are often observed at a discrete set of locations and times.

This research focuses on weather data provided by ECMWF reanalysis that are being used increasingly for those process descriptions. Major dilemmas locally are that observations are sparse, and the use of ECMWF reanalysis data is prone to uncertainty because of the coarse spatial resolution and systematic bias. The complete study of dependencies will also lead to an increase in the number of the involved variables.
