These data related to the MS are the raw data. The data is composed of the annual radial growth of the species of Daniellia oliveri collecte in the Sudanian zone of Mali. The cumulative growth diameter calculated from the annual radial growth. the annual precipitation from 1920 to 2020, the mean annual temperature from 1950 to 2020. There are also the data related to the chronologies (Standard chronology and residual chronology) developed from the species of Daniellia oliveri. The results show that the rainfall are the main factor influencing the tree growth in our study area while the temperature has influence on the growth of the species of Daniellia oliveri. The species of Daniellia oliveri can be use for dendroclimatology studies.


Steps to reproduce

The samples disks of Daniellia were collected on the field in Mali and have being transported to the laboratory of Dendrochronology in Nairoby, Kenya. We did different analyses, like wood anatomy in order to make sure if the rings are visible or not. We used standard dendrochronological methods to process the samples in the laboratory. Tree-ring measurements were carried out on the longest two radii. These tree-ring boundaries were marked under a microscope connected with a LINTABTM 6.0 measuring systems. Each tree-ring width was measured with a precision of 0.001 mm using the LINTABTM 6.0 associated to the software TISAP-Win.
