Satellite Remote Sensing for Measuring Urban Heat Islands & Constructing Heat Vulnerability Indices: ARSET Training

by sarah.cutshall » Wed Jul 06, 2022 10:52 am America/New_York

NASA’s Applied Remote Sensing Training Program (ARSET) and the National Integrated Heat Health Information System (NIHHIS) has opened a new open, online webinar series: Satellite Remote Sensing for Measuring Urban Heat Islands and Constructing Heat Vulnerability Indices. This 4-part, advanced webinar will build on ARSET’s urban heat island training held in November 2020 with hands-on exercises for participants to measure urban heat islands (UHI) and construct heat vulnerability indices (HVIs) for their areas of interest.

Satellite Remote Sensing for Measuring Urban Heat Islands and Constructing Heat Vulnerability Indices

Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes such as forests and water bodies. Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas. These pockets of heat are referred to as “heat islands.” The rapid growth of urban populations, the urban heat island effect, and increase in the frequency and duration of heat waves due to climate change, raise a series of issues about the increased health risks of sensitive urban populations to extreme heat and the effective means of mitigating the impacts of heat waves.

Remote sensing provides global, timely, objective 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 inform where and when land use and land cover have changed over time and 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. This four-part, advanced webinar will build on ARSET’s urban heat island training held in November 2020 with hands-on exercises for participants to measure UHI and construct HVIs for their areas of interest.

This webinar series is a collaboration between NASA’s Applied Remote Sensing Training Program (ARSET) and the National Integrated Heat Health Information System (NIHHIS).

Learning Objectives:
By the end of this training, participants will be able to:
-Define what an urban heat island is and why it matters to urban planners and public health experts
-Map land surface temperature from Landsat 4, 5, 7, 8, & 9 using Google Earth Engine and source complementary urban heat measurements
-Engage with local decision-makers to identify the socioeconomic inputs appropriate for constructing heat vulnerability indices
-Apply common techniques used to create heat vulnerability maps for an urban area of interest

Audience: Community, municipal, city, state, federal, and private institutions involved in urban planning, health care, energy supply and demand management, and climate mitigation.

Course Format: Four, 1.5-hour parts
