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

General description 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.   Data description indoor_grasp.csv file (time series) temporal resolution: 1 min.

Maximum and minimum wind speeds have been filled by propagating the last recorded value. The mass of JIM, air temperature, humidity, wind speed, wind direction, solar radiation, evaporation, and Qt_tot were filled by linear interpolation. The two watering events explain the observed peaks in outflow from the roof on September 24 and 30. The disconnection of the weight measurement system on 10/31/2024 at 08:59 UTC caused a negative spike in weight tracking. This value was corrected, as the weights recorded in the minutes before and after were identical (at 956kg). Nov: No minutes are missing in November. The tips from November 4th for JIM and the pluviometer were erased. Dec: No minutes are missing in December. Jan: No minutes are missing in January. Feb: No minutes are missing in February. A correction was made on 02/13/2025 at 10:19 on JIM’s weight, probably due to the synchronization of the control center. Since the points before and after were at 1037 kg, the point at 10:19 was also set to 1037 kg. March: No minutes are missing in March.   1x1 sq. m setup EVENTS OVER THE PERIOD 11/04/2024 14:15-15:30 13:15-14:30UTC: Verification of the rain gauge buckets and the 1x1 roof. no event in December no event in January 02/06/2025: visit 02/13/2025 10:19:00: Time adjustment of control centers 02/25/2025: visit 02/26/2025: visit RAW DATA Nov/Dec:  No minutes are missing in November and December. The tips from November 4th for 1x1 and the pluviometer were erased. Jan: No minutes are missing in January. Feb: No minutes are missing in February. March: No minutes are missing in March. A correction on the 1x1 weight was made on 03/26/2025 between 13:33 and 13:39. These weights were fixed at 156.6 kg due to some unusual values, probably caused by the visit.   Acknowledgements The authors acknowledge financial support from the European Union under the Horizon 2020 program within acontract for Integrating Activities for Starting Communities (Ref. 101008626).
