Abstract :
Land surface albedo has large daily and seasonal variation in many regions. Malaysia, for being located at the tropical region, experiencing constant illumination of sun and receiving two monsoon seasons namely northeast and southwest and two inter-monsoon seasons in Mar-May and during Oct-Nov, the diurnal variation of heat may somewhat be different. This study attempts to investigate the relationship between land surface albedo (LSA) derived from the MODIS with the selected air quality parameters. The objectives includes to determine significance relationship between LSA with ambient temperature and to identify the significance factor of other identified variables such as UVB, windspeed, Humidity and CO2. Using linear trend correlation analyses technique based on Pearson correlation coefficient, the strength and direction of the relationships between MODIS spectrally derived LSA are identified along with the relationship between selected dependent and independent variables were visually inspected.
