It’s not the longest climate dataset, but it may be the longest directly recorded by humans. All of these types of data are climate proxies (alternate indicators we can use to gain information about historic climates), the longest of which are ice core measurements.
Idk, egyptian priests kept records of the groundwater levels to predict the nile flood times to keep the peasants in check, and that could count as a climate dataset that far predates and is longer than this.
