oa CSIR Science Scope - Modelling vegetation phenology from 20 years' daily satellite data : statistical modelling

Volume 2, Issue 4
  • ISSN :



CSIR researchershave used close to 20 years of daily satellite imagery to model vegetation phenology, allowing unique analyses of patterns across the entire southern Africa. Vegetation phenology examines life cycle events such as bud burst, flowering and leaf senescence. The phenology of terrestrial ecosystems reflects the response of the biosphere to proximal climatic factors (e.g. temperature and rainfall). Phenology can thus be used to identify and descriptionbe different vegetation types and to monitor vegetation responses to changes in these climatic determinants. Vegetation phenology has already shown clear changes in the northern hemisphere during the past 20 years, with growing season length increasing by up to a month.
