Roma Capitale: Interactive and Dedicated Climate Monitoring System on the Dataclime Platform

Roma Capitale and the CMCC Foundation (Euro-Mediterranean Center on Climate Change) present a new open-source service — the first interactive climate monitoring system for Roma Capitale — developed to support the implementation of the Climate Adaptation Strategy approved by the City Council in January 2025. This innovative tool provides climate data from multiple sources across the entire municipal territory, integrating weather stations, climate models, and satellite data to deliver a comprehensive and reliable picture of Rome’s urban climate.

The service, freely accessible on Dataclime upon registration, enables interactive monitoring of the most relevant climate indicators for Rome, with a particular focus on identifying the most vulnerable areas, such as urban heat islands. It consists of four main sections, each based on a different data source: weather stations, a very high-resolution dataset (~2 km) developed by CMCC, satellite imagery, and climate projections.

Data from the first report highlight that 2024 was the hottest year for Rome since 1991, with a mean temperature of 19.7°C (+2.5°C above the 1991–2020 average), 36 tropical nights (nearly 30 more than average), and 53 days of extreme thermal discomfort (+29 above average). The tool will support urban planning and climate risk management, providing critical inputs to address the four strategic priorities identified: heavy rainfall and flooding, water security, adaptation to high temperatures, and coastal protection.

Maps and charts are available for free download via the Dataclime platform, offering a valuable resource for anyone interested in studying climate change across Rome’s municipal territory. Users are advised to consult and comply with the disclaimer associated with the use of results, to ensure correct and informed application.
