Online-workshop “Individual Planning of the ExLabs for Assisted Users”
On 13th of June 2022 ProPolis scientists have met virtually with practice partners from seven municipalities that are applying urban climate model PALM-4U by themselves (“assisted users”). After communicating the requirements to practice partners and discussing pending tasks and responsibilities, participants have set individual action plans for the coming ExLab-workshops.
Online-workshop ExLab “On-site” with the city of Remscheid
On 2nd of June 2022 an individual workshop with the practice partner city Remscheid took place as an online event. The city of Remscheid proposed ProPolis scientists to investigate a climatological question of modelling the future climate for the entire city for the years 2031-2060. ProPolis modelers applied the urban climate model PALM-4U to simulate this application case and presented the simulation results to practice partners in the ExLab. For this application case a threshold “Hot day” was used to model the cold air balance and thermal comfort under current conditions and compare it with a climate change scenario in a near future. In particular, focus areas such as a river dam or a special hilltop location of the city showed some interesting simulation results.
In the end, the participants from different disciplines discussed the integration of simulation results in municipal planning processes and shared their views on continuation of PALM-4U services after the end of the project.

ProPolis modelers applied PALM-4U model to investigate the day and night situation for forecast year 2030 under current conditions (without new urban district) and with a planning scenario for the new urban district. In the first part of the workshop they presented comparison of simulation results for the thermal comfort situation with and without new urban district on the area of 150 ha where cold air is currently being generated. With the help of maps and comparable indicators the participants found out about climatic impact of the planning scenario under forecasted climate change conditions.
Following, the participants discussed the integration of simulation results in municipal planning processes in two breakout groups. The results of the workshop will feed into the evaluation of the model practicability.
First PALM-4U training module “Preparation of input data”
On 09th and 10th of February the first virtual PALM-4U training for the practice partners took place. The goal of this two-day training module was to familiarize the partner cities with the basics of input data preparation for the urban climate model PALM-4U.
On the first day ProPolis scientists presented the newly developed graphical user interface (GUI) and the PALM input data format “static driver”. On the second day the participants have learned to create “static driver” by themselves with the help of step-by-step video instructions. For this, they applied the newly developed software tools for the first time: QGIS plugin “PALMClassify” and the PALM-4U GUI. During this practical exercise, practice partners also tested freshly launched PALM-4U Service desk. In addition, they could directly clarify their questions with ProPolis experts and give their first feedback in a virtual Q&A session.
In the next training modules the practice partners will learn the entire workflow with PALM-4U GUI and gradually build up their capacities in independent model application. The PALM-4U GUI and the Service desk will be tested under real-life settings and further developed.
