Webinar: Satellite Remote Sensing for Measuring Heat Vulnerability

Buildings, roads and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes. Urban areas, where these structures are highly concentrated and greenery is limited, become “heat islands” of higher temperatures relative to outlying areas. Remote sensing provides observations to monitor the effects of urban heat islands (UHI) over time. Thermal mapping from satellites can be used to monitor land surface temperature (LST), while optical data collected from satellites can be used to approximate air temperatures. Once UHIs have been mapped, incorporating socioeconomic data pertaining to population, demographics and health information into heat vulnerability indices (HVI) can help guide interventions to manage heat-related risks to public health. NASA is offering a four-part, advanced webinar with hands-on exercises for participants to measure UHI and construct HVIs for their areas of interest. The webinars will take place from 8-9:30 a.m. on August 2, 4, 9 and 11. Visit for more information and to register
