The number of historical reports of dry or wet conditions in and near Brazil for (a) 11 of the 12 driest and (b) 7 of the 11 wettest years from 1790 to 1900 in the precipitation reconstruction. The number of historical sources used to produce these maps is tallied in Table 6 in the online . The tree-ring-reconstructed wet-season precipitation totals based on the C. odorata chronology from Rio Paru-Baixo (Granato-Souza et al. 2020) are also indicated for the (c) dry and (d) wet extremes (upper and lower 10th percentiles; red and blue, respectively). The year 1875 is omitted from the composite map for the dry years [in (c)], and 1891 is omitted from the map for the wet years [in (d)].
