Abstract
This dataset contains microclimatic data collected in June and August 2019 in Bologna, in the framework of ROCK project. The data underly a research aimed at comparing microclimate conditions and people density in areas framed by the presence of ROCK temporary actions and events. In order to achieve this goal, microclimate analysis have been performed by the Department of Architecture of the University of Bologna using data from the open portal of ARPAER (https://www.arpae.it/it) and from the sensors installed by the ROCK project in the area. ARPAER data have been inserted in the ENVIMET software, according with the methodology briefly described in the Methodology section of file ROCK_WP2_T2-4_Tool8ENVIMET_202102_v1_README.rtf, and more completely into the provided guideline (file named ROCK_WP2_T2-4_Tool8ENVIMET_Guideline.pdf). Results of the model have been validated through the results of the sensors installed in the area. The documents inside the subfolder named 01_Tool-08-ENVIMET-DATA-LOCAL-SENSORS-calibration contains this step of the process.

Methodologies 

Area selected for ENVI-met area simulation. 

The Outdoor Microclimate Map (OMM), obtained through ENVIMET software, reports two variables: air temperature (°C) and Physiological Equivalent Temperature (PET, measured in °C). 
The selected ENVIMET model area has been a grid with 140x170 cells, each of 1.5x1.5m, so the total dimension of the area is 210x250m. The data related to weather have been taken from Dexter ARPAER, Bologna City weather station. 
Day of simulations were selected as following: 
•	26th June 2019, with the concert of Neri Marcorè. In this day the outdoor average air temperature was 27.8 °C; 
•	27th June 2019, without any public events and with an outdoor average air temperature of 27.8 °C; 
•	16th August 2019, without public events and with an outdoor average air temperature of 23.4 °C; 
•	17th August 2019, with the public events Opera Tosca and an outdoor average air temperature of 24.6 °C.
For each day the initial boundary conditions were defined as following: 
•	starting date: 04.08.2017
•	starting time: 06:00 
•	simulation time: 24 h, with the 2nd day used for evaluation
•	wind speed measured at 2 m of height (in m/s): 1,86 m/s
•	wind direction (in degrees): E 97°
The duration of the software calculation time was around 180 - 200 hours for each simulation. 
We simulated 4 Outdoor Microclimate Maps for both areas, one for each of the 4 days, and including the variables air temperature and PET at 12:00, 16:00, 20:00 and 22:00. The total maps obtained has been 48 Outdoor Microclimate Map. 
Figure reports an example of results’ comparison for each data, with and without public events, with OMM at 12:00, 16:00, 20:00 and 22:00 hours, and considering air temperature and PET; so, we can see the outdoor microclimate variation and the extension of the crowd for each hour.
