The ITRDB accepts all tree ring data with sufficient metadata to be uploaded, but was originally founded with a focus on tree ring measurements intended for climatic studies. Specific information is required for uploading data to the data base, such as the raw tree ring measurements, an indication of the type of measurement (full ring widths, earlywood, latewood), and the location, but the types of data and the rules for accuracy and precision of the primary data, tree-ring width measurements, are decided by the dendrochronologists who are contributing the data rather than by the NOAA or another governing organization. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「International Tree-Ring Data Bank」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
