Co-UDlabs _TA_20/06_INSA-GROOF: Sub-hourly Hydro-Meteorological Data of Green Roof Test Plots with Different Dimensions (1m x 1m and 3m x 3m) in Lyon, France

This repository includes the datasets of the Co-UDlabs Transnational Access Project INDOOR-GRASP (Intercomparison of the hydrological Response of Green Roofs Across Scales, sites and experimental setups). The novelty of this project lies especially in the idea to conduct a paired green roof experiment, considering open site experimental plots at INSA Lyon (GROOF) and smaller indoor test plots built in the laboratory. Therefore, a 3x3 sq. m and a 1x1 sq. m test plot have been installed at the GROOF facility on the roof a building of the Institut National des Sciences Appliquées (INSA, Lyon). Measurements have been collected between September 2024 and March 2025. The project aims at developing a model which can be utilized to scale between both type of dimensions. In a later step, indoor experiments are also foreseen to focus on differences between open field and indoor test plots for green roofs. Whilst being a fascinating research question itself, it has high practical relevance: with this approach, the results of shorter (indoor) measurement campaigns can be scaled to long-term behavior through the outcome of this paired experimental and hydrological model approach. New green roof products can be tested more readily in order to proof their functionality.
