===== 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 [[http://en.wikipedia.org/wiki/Comma-separated_values|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\\ \\ |
