May-July precipitation reconstruction in the northwestern Qinghai-Tibet Plateau from 845–2023 CE

This is a May–July precipitation reconstruction for the northeastern Qinghai-Tibetan Plateau using a well-replicated ensemble tree-ring-width chronology from 350 Qilian juniper samples, spanning 845–2023 CE. The sampling informatin can be obtained from the paper entitled 'Recent and future climate extremes in the northwestern Qinghai-Tibet Plateau under anthropogenic forcing' submitted to Gephysical Research Letters.
