Abstract
This paper evaluates the effect of three climate parameters on forest cover in Ghana and
the normalized difference vegetation index (NDVI) at Digya National Park derived from
Landsat image data. Climate data (temperature, humidity, dewpoint, rainfall) are
assembled from statistics provided by Ghana's Meteorological Agency. The study
introduces a weighted averaging method by computing weather information from
neighbouring stations. Also, this research introduces a model of dewpoints, enabling the
direct calculation of dewpoints from temperature and humidity data. The major finding is
that while temperature significantly affects forest cover and Park vegetation, dew-points
and rainfall do not. The paper suggests where future research may be more fruitful in
analyzing the effects of climate on vegetation.
