    Rural background stations provide insight into seasonal variations in pollutant concentrations and allow for comparisons to be made with stations closer to anthropogenic emissions. In Malaysia, the designated background station is located in Jerantut, Pahang. A fifteen-year data set focusing on ten major air pollutants and four meteorological variables from this station were analysed. Diurnal, monthly and yearly pollutant concentrations were derived from hourly continuous monitoring data. Statistical methods employed included principal component regression (PCR) and sensitivity analysis.

    Mengenal Pasti Tren Berekanada di dalam Parameter Perubahan Iklim di Kluang dan Senai, Johor, Malaysia
    (Penerbit UKM, 2017) Firdaus Mohamad Hamzah; Farahani Mohd Saimi; Othman Jaafar
    Perubahan iklim memainkan peranan yang penting pada masa kini berikutan kesan serius terhadap kehidupan di bumi. Analisis tren perubahan iklim amat penting dalam mengenal pasti perubahan coraknya kerana analisis ini dapat memberi gambaran awal dalam membuat analisis lanjutan. Dalam kajian ini, analisis tren dilakukan untuk melihat perubahan iklim bagi parameter perubahan iklim, iaitu jumlah jatuhan hujan bulanan (mm), purata suhu bulanan (°C), purata radiasi global bulanan (MJm-2), purata kelajuan angin bulanan (m/s) serta purata kelembapan bulanan (%) sepanjang tempoh 1974 sehingga 2010.
