EO-Based Heat Island Identification service
University of Valencia’s EO-Based Heat Island Identification service is now available for usage, providing 30-m daily LST data for the four pilot cities registered in CityCLIM.

The 30-m LST is being produced fusing data from multiple thermal sensors onboard satellite platforms reaching an accuracy of around 1ºC and reproducing the spatial patterns recorded by medium and high resolution termal images

The Surface Urban Heat Island Index map for June 14 over Valencia shows how important are parks and water bodies for the heat regulation on urban areas. Where the park area near Ciudad de las Artes y las Ciencias exhibits temperatures 5 degrees lower than the average temperature of the city.
We conducted an extensive field campaign in Valencia to measure Land Surface Temperature (LST) at various locations across the city. These ground-based measurements are intended to validate and enhance the accuracy of satellite imagery captured by OHB’s Raven sensor.
By comparing the field data with the satellite-derived LST, we aim to refine the calibration of the sensor, ensuring more reliable results. This improved data will serve as a critical input for a range of urban heat studies, providing valuable insights into local heat island effects, thermal comfort assessments, and urban planning initiatives aimed at mitigating extreme heat conditions.
