This dataset contains planktonic foraminifera Mg/Ca-derived temperature estimates, age control points and δ18O of 5 sediment cores ODP807 (156.625ºE, 3.61ºN, 2804 m water depth), KX21-2 (157.98ºE, 1.417ºS, 1897 m water depth), MD10-3340 (128.725ºE, 0.517ºS, 1094 m water depth), SO18480-3 (121.65ºE, 12.058ºS, 2299 m water depth) and MD98-2162 (117.9ºE, 4.69ºS, 1855 m water depth) from the Indo-Pacific Warm Pool (IPWP) over the last 360 ka. Also included are planktonic foraminifera-based IPWP stacks of SST, TWT, upper OHC above 200 m and sea water δ18O (δ18Osw), reconstructed from these five cores and five previously published records in the IPWP (GeoB17426-3: 150.86ºE, 2.188ºS, 1367 m water depth; MD01-2386: 129.793ºE, 1.13ºN, 2816 m water depth; MD06-3067: 126.5ºE, 6.514ºN, 1575 m water depth; SO18460: 129.237ºE, 9.089ºS, 1421 m water depth; MD01-2378: 121.788ºE, 13.083ºS, 1783 m water depth). To reveal the modulation of IPWP OHC on ocean-continent hydrological cyle, we also attached numerical simulated upper OHC (above 200m), δ18Osw (sea water) and δ18Op (atmospheric rainfall) from a 300kyr's transient simulation of the NASA GISS-ModelE2-R model (totally 3000 model years with a acceleration factor of 100). The annual mean OHC and δ18Osw are regional averaged over 15ºS-15ºN, 110ºE-160ºW, and over 5ºS-15ºN, 140ºE-170ºE, respectively. The annual and summer (July-August-September) mean δ18Op are averaged over East Asia (15ºN-40ºN, 85ºE-125ºW). Another upper OHC data (above 20℃ isotherm depth) is also provided by a simulation of the NCAR CESM model under the 300kyr's transient forcing of orbital parameters and greenHouse gases.
