 
Weather data
A large number of automatic weather stations has been implemented in the frame of the BIOTA AFRICA project by the Namibian National Botanical Research Institute (NBRI) and the Group "Biodiversity, Evolution and Ecology" (BEE) of the University of Hamburg. The website offers hourly updates of data and graphs of a large number of weather parameters.

| Dataset metadata |
| Description | Stem girth increment of 1198 trees larger 10cm DBH (diameter at breast height) was recorded monthly in Kakamega (N=817) and Budongo Forest (N=381). The trees were located in permanent sample plots (20 by 20 meters) in the BDOs as well as additionally chosen single trees. Apart from stem increment changes in the flowering, fruiting and foliage characteristics were observed. |
| Purpose |
Characterizing and analyzing tree growth for different species in response to biotic/abiotic factors |
