Work Package 3 focuses on developing and applying downscaling techniques to localize climate forecast simulations at relevant spatio-temporal scales. By further advancing downscaling techniques, IMPETUS aims to provide localised climate information critical for climate adaptation and resilience strategies at the local level.
Highlights include:
- Tools and Techniques: The main tools in WP3 are standard empirical statistical downscaling techniques (ESD) and new hybrid downscaling approaches (model emulators).
- CRCM Emulators: IMPETUS proposes a new approach to tackle the challenge of dynamic models which require large ensembles to capture the range of natural variability and costly fine-scale climate models. CPRCM simulations are conducted over large domains in Europe to train and evaluate hybrid downscaling techniques. These techniques will then be applied to downscale global climate prediction ensembles. CPRCM simulations focus on the present as well as projection scales.
- The three phases of implementation are: 1. development and evaluation of CPRCM simulations and hybrid downscaling techniques, 2. application of these techniques to downscale global climate prediction ensembles, and 3. delivery of localized climate information for use in other project components.
- Potential Applications: Emulators have the potential to produce localised and reliable climate information in Europe and the demonstrator cities specifically, contributing to hazard assessment and risk analysis. WP3 aims to develop and compare different approaches to deliver emulated localised climate fields for each city demonstrator.
