Urban Climate Information to Support Decision Making: from Local to Global in Salon 12
14:45 - 16:15
To maintain or improve the quality of living in cities, urban planners need detailed information on future urban climates at a residential scale but most of the global climate models do not adequately account for the urban environment. In fact, cities affect the local weather by perturbing the wind, temperature, moisture, turbulence, and surface energy budgets. The foundation of urban-scale climate information is our current high-resolution urban downscaling expertise, combined with local-impact models, and ensemble dynamical and statistical downscaling. This combination enables the propagation of climate change and uncertainty from global to the city scale. The first part of this session will address critical knowledge gaps around downscaling to city-scales and how to assess and reduce uncertainties; this will be critical input to the forthcoming IPCC scientific assessments. Complementing this focus on models, the session will also look at observations. The Global Climate Observing System Terrestrial Observation Panel for Climate (GCOS-TOPC) is responsible for identifying and facilitating the monitoring of Essential Climate Variables (ECVs) that feed into IPCC/UNFCCC climate assessments. GCOS-TOPC is responsible for several critical ECVs including global surface albedo, land cover change and soil moisture, and as a matter of priority is currently considering one or more ECVs that represent evolving human adaptation to climate change in critical terrestrial realms, including cities. Through a facilitated panel and audience interaction, the second part of this session aims to make important progress on the identification of such ECVs and how they may be efficiently measured/monitored. Such variables representing urban adaptation might be physical (e.g. changed urban characteristics from satellite observation), or socio-economic (e.g. direct funding invested in adaptation response). Development of appropriate city-related ECVs will be a lasting legacy of this Cities IPCC Conference.

Guide for Integrated Urban Weather, Environment and Climate Services (IUWECS) and how it can best meet the needs of researchers and stakeholders in Salon 8
11:00 AM - 12:30 PM
The Integrated Urban Weather, Environment and Climate Services (IUWECS) is a new initiative from the World Meteorological Organization (WMO) that seeks to provide science-based integrated urban services supporting safe, healthy and resilient cities. As part of that initiative, a Guide for IUWECS is being developed. The CitiesIPCC conference provides an excellent opportunity to present and receive feedback from attendees on the guide because the conference falls within the period for open community review.
The intent of the IUWECS Guide is to document the best available knowledge, technologies and practices for producing and providing the relevant services that cities require to respond to the hazards posed by climate change. Such services include a combination of dense observation networks, high-resolution forecasts, multi-hazard early warning systems, and climate services. These services should assist cities in setting and implementing mitigation and adaptation strategies, which will enable the building of resilient and thriving cities that promote the Sustainable Development Goals (SDGs). The Guide also plans to include a multidisciplinary approach to better serve the social-economic needs of urban areas, and identify the required partnerships to establish and sustain urban services, including research, city governments, international organizations, and private sector stakeholders.
The session presentations will illustrate the best available knowledge/technologies and practices. Feedback will be obtained from participants on desired services, products and requirements for developing effective multidisciplinary partnerships among urban/city governments with meteorological and other key agencies.
