Primary metric measurements of European tree rings in one dataset in JSON format.
The International Tree Rings Data Bank (ITRDB) is the most comprehensive tree growth database (https://www1.ncdc.noaa.gov/pub/data/paleo/treering). Shoudong Zhao, et al. (2019, 2018) analyzes the representativity of dendrochrono-logical data (ITRDB) and proposes a corrected database with error indications. One of the bottlenecks of data use (ITRDB) is that the data is loaded as a collection of separate files in the Tucson positional format. The purpose of our data presentation is to change the Tucson data format to JSON format and combine the separate files into one. The initial data for Europe in the volume of 2244 rwl-files are converted into Json format of tree growth data in one file. The R programming language and the dplR program library Bunn, A. (2008) The experience of developing the structure of dendroclimatic data in JSON format is described in the works of Kachaev A. (2016, 2017, 2020).
