New northern NE Brazil (NEB) precipitation record. (a) Thermoluminescence (TL80–120) sensitivity of the 110 °C peak from marine sediment cores GL-1248 (0.92°S, 43.40°W) and GeoB16206-1 (1.58°S, 43.02°W)21 (details regarding merging these records are available in Text S1 and Fig. S1). (b) TL sensitivity record filtered in 0.026 ka frequency (19 ka, FIR filter) within software PAST v4.0346. (c) November–January (NDJ) insolation (W/m2) at 10°S47.
