Past temperature reconstructions offer valuable insights into the impact of climate change on the global climatehuman-vegetation system.Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are recognized as effective temperature proxies, particularly in lakes and peatlands, where they are well preserved.However, their reliability as palaeothermometers can be compromised by factors beyond air temperature, especially in drylands.This study introduces the Arid Central Asian (ACA) brGDGT surface Data Base, a regional dataset consisting of 162 new surface samples from the drylands of ACA, in
