High-Resolution Satellite-Derived PM2.5 Concentration Maps for Northern Thailand during the Burning Season (2020–2024)

This dataset provides high-resolution (1x1 km) spatial distribution maps of surface PM2.5 concentrations in Northern Thailand during the burning season [January to April] for the years 2020 to 2024. Methodology: The PM2.5 maps were estimated using a multi-source satellite integration approach within the Google Earth Engine (GEE) platform. The model integrates Aerosol Optical Depth (AOD) from TERRA-MODIS (MCD19A2) with trace gases (CO and NO2) from Sentinel-5P TROPOMI, validated against ground-based measurements from the Pollution Control Department (PCD) of Thailand.
