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
