Description

We created a synthesis of IPWP (Indo-Pacific warm pool) hydroclimate during the LGM using proxy data, to better understand the tropical response to glacial background conditions. See DiNezio and Tierney (2013) for more details.

terr_raw and marine_raw files contain the locations and hydroclimate state at the LGM from a collection of proxy records

terr_gridded and marine_gridded files are the final “gridded” data as seen in the main text of DiNezio and Tierney (2013), in which proxies were averaged within a search radius of 150 km

The csv text data files contain the following columns (beside the self-explanatory Location, Core ID, Proxy and Reference columns):

Column name	Detail
Longitude	Longitude of grid-cell center (degrees East)
Latitude	Latitude of grid-cell center (degrees North)
Category	Indicates whether the proxy captured: dry(val=-1)/unchanged(val=0)/wetter(val=1) fresh(val=-1)/unchanged(val=0)/salty(val=1) climate at the LGM
Is_robust	_raw files: Is_robust=1 indicates when different proxy techniques agree in their estimates of LGM hydroclimate at each location Is_robust also takes the value of 1 when only one proxy technique is used _gridded files: is_robust=1 indicates that the observations merged into each “gridded” point agree is_robust=0 merged observations did not agree
N_obs	Number of proxy techniques used to estimate LGM hydroclimate from each location
chrono_flag	_raw files only: chrono_flag=1 indicates whether the proxy record contains one or more radiocarbon U/Th or well-constrained OSL dates near to or during the LGM chrono_flag=0 indicates that the LGM was dated via wiggle-matching the local benthic d18O to a global stack or another method
