Percy Yvon Rakoto

Percy is a spatial analyst and researcher in climate adaptation, dedicated to making cities cooler and more livable through data-informed urban greening. He uses GIS and scenario-based simulations to design effective tree planting strategies. By integrating geospatial modelling with land cover analysis, he examines how urban structure, vegetation, and built surfaces affect local air temperatures. His work aims to promote climate-resilient urban development, especially in vulnerable communities.

Evaluating the reliability of Crowdsourced Weather data for urban heat assessment: a case study in Melbourne
Percy Yvon Rakoto

This study assesses the reliability of Citizen Weather Stations (CWS) for urban heat analysis in Melbourne using CrowdQC+ and spatial interpolation. After quality control, 277 of 465 stations remained. CWS data recorded slightly higher temperatures than professional stations, with accurate predicted vs. observed comparisons (R² = 0.989; RMSE = 0.306).
