Óbuda University – GreenQual Project
Date: November 17–21, 2025

With the participation of Óbuda University, a measurement campaign organized as part of the GreenQual project took place in Kraków from November 17 to 21, 2025. The aim of the campaign was to collect urban environmental data for the validation of simulation models and to establish baseline (status quo) models.

Marcell Nánási served as the technical lead for the measurement campaign, responsible for coordinating the entire process and managing on-site operations. Martin Kolman played a key role in the successful execution of the campaign; drawing on his technical expertise, he directly operated the most critical measuring instrument, ensuring data accuracy, and also actively participated in the technical preparation processes.

Borbála Fodor and Balázs Szucsán, students at the Ybl Miklós Faculty of Architecture and Civil Engineering, as well as staff members from the University of Agriculture in Kraków—Dr. Barbara Czesak, Dr. Renata Różycka-Czas, and their students—participated in the implementation of the measurement campaign. We would like to take this opportunity to thank them for their on-site support and cooperation. The campaign was hampered by unfavorable weather conditions, but thanks to the team’s persistent efforts, all planned measurements were successfully carried out.

Measurement Locations

The field measurements were conducted at three distinct urban locations in Kraków:
• Św. Tomasza 23
• Plac św. Marii Magdaleny
• Henryk Jordan Park

At each site, four measurement series, each lasting 30 minutes, were conducted. The measurement points were designated and the measurement structure was established in advance, prior to the campaign, ensuring that on-site data collection proceeded according to plan and in a standardized manner.

Measured Parameters

The following environmental parameters were recorded during the campaign:
• wind speed and wind direction
• air temperature
• relative humidity
• air pressure
• illumination (luminance)
• air pollution indicators

Participants

The following individuals from Óbuda University participated in carrying out the measurement tasks:
• Marcell Nánási (campaign leader)
• Martin Kolman (instructor)
• Borbála Fodor (student)
• Balázs Szucsán (student)

The successful implementation of the campaign was significantly aided by the cooperation of the University of Agriculture in Kraków. The fieldwork was supported by:
• Dr. Barbara Czesak
• Dr. Renata Różycka-Czas
as well as the institution’s students.

Weather Conditions

During the measurement campaign, participants faced unfavorable weather conditions, including low temperatures and rainy weather. These factors made fieldwork difficult; however, thanks to careful preparation and the participants’ dedicated efforts, the entire measurement program was successfully completed.

Results and Applications

The data collected during the campaign are of fundamental importance:

• for validating urban environmental and microclimate models,

• as well as for refining and further developing baseline models.

The measurement campaign contributes to achieving the technical objectives of the GreenQual project and strengthens international research collaborations.
