Di dalam sesi ini saya akan membangun model sederhana spatio-temporal kualitas udara NO dan NO2 di Kota Surabaya. Permasalahan yang paling utama adalah keterbatasan stasiun pemantau yang hanya berjumlah lima (5) buah saja, itupun sering tidak beroperasi karena rusak. Berikut abstrak secara umum.
In the present study we measure and formulate a simple spatio-temporal model of daily observation air pollutants NO and NO2 over the city of Surabaya, Indonesia. Our specific objection is to formulate a model to predict the concentration over time and space based on observations from a very limited number of monitoring stations. Our simple concept follows a simple concept of first predicting the time trends at the monitoring stations and then expanding for space to measure locations where there is no monitoring stations using kriging and IDW method.
