INTRODUCTION

  • Temperature rise is the result of both natural and human activities
  • Currently, temperature analysis is relying on in-situ measurements in Rwanda
  • A combination of in-situ measurements and remotely sensed data can significantly improve temperature quantification over wide space in Rwanda.

​

Problem Statement

Heat energy has become a challenging point of concern for a long time. It is highlighted to be an inevitable cause of ambient air quality change and new disease generation

Fire burning 2013

  • 64 ha of crops in Rwanda
  • 5 people dead and 36 injured
  • 86 houses and 18 clasrooms

Floods and Drought

  • Rising global temperature mean more rain.
  • $43 million per year are lost in Rwanda.

EFFECTS OF TEMPERATURE RISE

EVALUATION OF SPATIAL VARIABILITY OF TEMPERATURE USING SATELLITE DATA

  • NDVI values have to fall between -1 and 1.

​

  • Then, the calculated NDVI shown in the left image indicates -0.898 as the smallest value and 0.969 as the biggest value

​

  • These extreme values exactly fall in the NDVI normal range

EVALUATION OF SPATIAL VARIABILITY OF TEMPERATURE USING SATELLITE DATA

This (Kigali) study include:

​

  • Buildings, roads, playground, as the most dominant class

​

  • Vegetation class.

​

  • This study does not include cloud, water body, and other objects with very small response to solar radiations.
