SPATIAL ESTIMATION OF AVERAGE DAILY PRECIPITATION USING MULTIPLE LINEAR REGRESSION BY USING TOPOGRAPHIC AND WIND SPEED VARIABLES IN TROPICAL CLIMATE Open

Mohd Talha Anees, Khiruddin Abdullah, Mohd Nawawi, Nik Norulaini Nik Ab Rahman, Abd Rahni Mt Piah , et al. · 2018

Complex topography and wind characteristics play important roles in rising air masses and in daily spatial distribution of the precipitations in complex region. As a result, its spatial discontinuity and behaviour in complex areas can affe…

Determination of Source’s Location of a Dipole Field using Euler Relation Open

Nuraddeen Usman, Khiruddin Abdullah, Mohd Nawawi · 2018

Magnetic materials such as rocks and other geological structures can be treated as an assortment of magnetic dipoles. This concept can be used to simulate magnetic response of a body if its parameters are known. Likewise, source location o…

New approach of solving Euler deconvolution relation for the automatic interpretation of magnetic data Open

Nuraddeen Usman, Khiruddin Abdullah, Mohd Nawawi, Amin Esmail Khalil · 2018

The conventional Euler deconvolution has 5 unknown parameters to be solve which are the location of source (x0, y0, and z0), the background field and the structural index (SI). Among these 5 unknowns, the SI is to be manually selected by t…

SPATIAL INTERPOLATION OF AEROSOL OPTICAL DEPTH POLLUTION: COMPARISON OF METHODS FOR THE DEVELOPMENT OF AEROSOL DISTRIBUTION Open

Sahabeh Safarpour, Khiruddin Abdullah, H. S. Lim, Mohsen Dadras · 2017

Air pollution is a growing problem arising from domestic heating, high density of vehicle traffic, electricity production, and expanding commercial and industrial activities, all increasing in parallel with urban population. Monitoring and…

One- and Two-Dimensional Hydrological Modelling and Their Uncertainties Open

Mohd Talha Anees, Khiruddin Abdullah, Mohd Nordin Adlan, Nik Norulaini Nik Ab Rahman, Muhammad Syakir , et al. · 2017

Earth processes, which occur in land, air and ocean in different environment and at different scales, are very complex. Flooding is also a part of the complex processes, which need to be assessed accurately to know the accurate spatial and…

Discriminating sediment and clear water over coastal water using GD technique Open

Abd Rahman Mat Amin, Mohammad Fadhli Ahmad, Khiruddin Abdullah · 2017

Currently two algorithms are being used routinely by the MODIS Atmosphere and Ocean Team in order to distinguish sediment influence and clear water pixels over turbid water area. These two algorithms require complicated computational analy…

Regional travel-time residual studies and station correction from 1-D velocity models for some stations around Peninsular Malaysia and Singapore Open

Abel Uyimwen Osagie, Mohd Nawawi, Amin Esmail Khalil, Khiruddin Abdullah · 2016

We have investigated the average P-wave travel-time residuals for some stations around Southern Thailand, Peninsular Malaysia and Singapore at regional distances. Six years (January, 2010–December, 2015) record of events from central and n…

Development of Regional TSS Algorithm over Penang using Modis Terra (250 M) Surface Reflectance Product Open

Abd Rahman Mat Amin, Khiruddin Abdullah, H. S. Lim, Muhd Fauzi Embong, Mohammad Fadhli Ahmad , et al. · 2016

Total suspended sediment (TSS) plays a significant role in the environment. Many researchers show that TSS has a high correlation with the red portion of the visible light spectrum. The correlation is highly dependent on geography of the s…

Seasonal Variations of Aerosol Optical Properties and Identification of Different Aerosol Types Based on AERONET Data over Sub-Sahara West-Africa Open

Mukhtar Balarabe, Khiruddin Abdullah, Mohd Nawawi · 2016

The uncertainty in the quantification of aerosol properties such as concentration, size, and composition, spatially and temporally makes regional studies important. Therefore, this study presents seasonal variations of aerosol optical prop…

Long-Term Trend and Seasonal Variability of Horizontal Visibility in Nigerian Troposphere Open

Mukhtar Balarabe, Khiruddin Abdullah, Mohd Nordin Adlan · 2015

A study of the long-term variability; trend and characteristics of visibility in four zones of Nigeria was carried out. Visibility and other meteorological data from NOAA-NCDC and aerosol index data over Nigeria during 1984–2013 are analyz…
