Description:

Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial cell membrane lipids that, when preserved in sedimentary archives, can be used to infer continental paleotemperatures. Although commonly used global calibrations capture a relationship between the distribution of brGDGTs and temperature, they underestimate temperatures for tropical regions as much as ~16°C. Furthermore,some global calibrations reach saturation at around 24 –25°C, and, in general, they have root ‐mean ‐squared errors (RMSEs ≈~4°C) that are too large for them to resolve small variations in paleoclimate variability in tropical regions. We present an in situ regional calibration of soil brGDGTs along altitudinal transects on bothﬂanks of the Eastern Cordillera of Colombia in the northern tropical Andes that spans ~3,200 m in
