SKOPE Provides Free Access to High Resolution Paleoenvironmental Data

Synthesis often involves integrating archaeological and environmental data. SKOPE (Synthesizing Knowledge of Past Environments) is a free web application that provides easy access to tree-ring based annual retrodictions of precipitation and temperature at 800m spatial resolution for the Southwest US for the last 2000 years (data values provided by PaleoCAR, which is calibrated to PRISM).  At a coarser spatial resolution (~50km), SKOPE offers annual reconstructions of the Palmer Modified Drought Index (PMDI; the successor to the Palmer Drought Severity Index or PDSI) for the contiguous 48 US states, also for the last 2000 years.  SKOPE offers animated maps and time-series graphical summaries of these environmental variable values for arbitrarily bounded study areas.

The SKOPE platform is quite flexible and able to manage very large datasets.  At this time, SKOPE only offers modeled data for the US. However, as time and funding allow, we expect to add additional paleoenvironmental datasets for the US and other areas of the world.

Retrodicted water year precipitation for the area encompassing the protohistoric Zuni towns in New Mexico, AD 1450-1700, smoothed with a 21-year centered running average. The year of the Pueblo Revolt, 1680, is highlighted.
