ABSTRACT: The northern part of Thailand always has PM₁₀ exceeding the standard value which causes danger to public health. Major cause arises from open burning and forest fires, in addition, its meteorology and topography are likely to accumulate PM₁₀. This study aims to determine the relationship between PM₁₀ quantity from the ground station and Aerosol Optical Thickness (AOT) from the Terra Satellite-MODIS system in Chiang Mai province in northern Thailand. The operations are 1) analyze data of PM₁₀ and AOT, 2) analyze the statistical relationship in five models, namely exponential models, linear models, logarithmic models, polynomials models, and power models, and 3) PM₁₀ and spatial AQI. The result found that it has a consistency between PM₁₀ and AOT and PM₁₀ and spatial AQI. The statistical relationship in five models found that January has the most R² in polynomials models, February has the most R² in logarithmic models, March has the most R² in power models, and April has the most R² in linear models and polynomials models.
