The programme 'Urban Climate under Change - [UC]²' lasts another three years from 01.10.2019 to 31.09.2022. The urban climate model PALM-4U developed in the last three years is to be further developed for municipalities and other practical partners as well as for scientific research. The German Federal Ministry of Education and Research (BMBF) is funding this project / initiative within the framework of the Strategy 'Research for Sustainability' (FONA). The German Aerospace Center (DLR) Project Management Agency is providing the programme 'Urban Climate Under Change'. Module B of the programme consists of the joint research project Three-Dimensional Observation and Modelling of atmospheric processes in cities (3DO+M).

Sub-project 1, Module B as well as the whole programme are co-ordinated by Prof. Dieter Scherer. Sub-project 1 is leading the cross-module working groups Data Management and Model Evaluation. It will also develop the 'Berlin data portal' which will provide observation data from Berlin, input data for PALM-4U as well as freely usable tools (e.g. for visualisation and evaluation of the data) for public use in the long term.

Long-term observations are continued with the (Urban Climate Observation Network – UCON) and will deliver further data for the evaluation of PALM-4U. The sub-project will perform sensitivity studies using PALM-4U simulations and carry out application-specific model evaluation using the example of internal variability of heat stress risks. By means of summer and winter real case simulations with PALM-4U for Berlin and its surroundings urban-regional processes, inner-city and microscale variations of atmospheric phenomena and processes in the planetary boundary layer will be investigated. In co-operation with the Humboldt and the Freie Universität of Berlin TP1 develops a concept for a one-year study course, thereby contributing to user qualification in Model C. Together with Module A an international comparison of various urban climate models is planned.
