this interpretation is based on the correlation with instrumental temperatures (last 100 years) and in the good correlation with other nearby temperature record (SST inferred from Ifaty-4 coral d18O)

more positive values of d18O are found with greater annual temperatures (specially when averaging previous 5 years)

Mean annual air temperatures influence the annual precipitation isotope composition.

Finnigan Delta Plus Advantage and a Kiel IV carbonate device coupled to a Finnigan MAT 253 MS both at the University of Brasilia

0.06 per mil for d13C and 0.09 per mil for d18O

Still, the amount effect does not explain the total variance in the iso- topic composition of precipitation (R2 = 0.3, p < 0.01)

Intensity of the South American Summer Monsoon (SASM) excerts the strongest control on precipitation isotopes

TP: added site elevation; ZK 07/01/2019: The first problem is that decimal separators have been lost from the isotope values. The second problem is that SP14APPE00A and SP14APPE02A duplicates the same record. One of them should be removed.
