On the quality of climate proxies derived from newspaper reports ? a case study
International audience In this paper, the quality of a reconstruction of daily snow frequency in the central Andes is evaluated by studying the atmospheric patterns related to anomalies in the reconstructed series. The origin of precipitation anomalies in this part of the world is relatively well kn...
