Abstract

The problem of underestimating or overestimating the aerosols loading over Mubi is inevitable because of the absence of ground stations over the region. Aerosols pollution is a global challenge to life forms as it affects human health, agricultural produce, thermal comfort and weather. The modulation between high and low thermal comforts over Mubi is quite disturbing. The aim of the research is to seek a more reliable approach to estimate the aerosols loading and retention over Mubi. Thirteen years aerosol optical depth (AOD) data was obtained from the Multi-angle imaging spectroradiometer (MISR). Mubi is located on latitude 10.27oN and longitude 13.27oE. Statistical tools, as well as analytically derived model for aerosols loading were used to obtain the aerosols retention and loading over the area. It was discovered that the highest aerosols retention over Mubi is 12.7%. The atmospheric constants and tuning constants over Mubi were documented as 0.67 and 0.71 respectively. Due to the volume of aerosols over Mubi, it is necessary to change the International Telecommunication Union (ITU) model which relates to signal budgeting.

Highlights

  • Atmospheric aerosols are systems of solid or liquid particles suspended in air or other gaseous environment

  • If there is a drastic drop in aerosol optical depth, there is the possibility that the particulates are majorly dust

  • This study proposes an inclusion of the attenuation due to moving aerosols layer into the International Telecommunication Union (ITU) model which is significant via the atmospheric constants over Mubi

Summary

Introduction

Atmospheric aerosols are systems of solid or liquid particles suspended in air or other gaseous environment. They have definite lifetimes and vary in size, there is a wide range of them, from flame synthesized nanoparticles and nanomaterials (Stahlmecke, et al, 2009). This basic properties makes it a source of concern as regards human health, thermal comfort, agricultural produce (because it modifies both rain pattern heat flux and cloud formation) and communication. Studies show that the dust quantity which varies from year to year is greater in the Northern parts of these countries and the dust particles become finer in size as they move further south (Rutherford, et al, 1999; Anuforom, 2007; Uduma, Jimoh, 2013)
