Questions Paleo precip Metadata Below you will find the data for the reconstruction of precipitation at El Malpais National Monument near Grants, New Mexico. The tree-ring chronology associated with this reconstruction can be found in the holdings of the International Tree-Ring Data Bank (ITRDB) as NM572.CRN (standard chronology on which the reconstruction was developed) and NM572R.CRN (the residual tree-ring chronology). Details on the statistical calibration and verification procedures used in this reconstruction can be found in the following references: Grissino-Mayer, Henri D. 1995.
