Introducing PaleoClimate & PaleoRun

3rd Annual PaleoGIS and PaleoClimate™ User’s Conference

2013

• Desktop application

• Employs a parametric approach to modelling the climate of ancient earth

• Computes sea level air pressure, surface air pressure, sea level temperature, surface temperature, wind direction and azimuth, ocean currents, coastal upwelling, and wetness

What is PaleoClimate?

• Built on work by J.T. Parrish, Scotese, Ross, &

Summerhayes

Scotese, C. R & Summerhayes, C.P. (1986). Computer Model of Paleoclimate Predicts Coastal Upwelling in the Mesozoic and Cenozoic. Geobyte

Origin of PaleoClimate

• Complementary to PaleoGIS

• Geologists and GIS professionals can

dynamically visualize and analyze a wide range of

paleoclimate scenarios that may have affected

the deposition of organic materials and the

formation of reservoirs.

Why did we build this tool?

● PaleoClimate can be launched from PaleoGIS

• PaleoClimate’s outputs are viewable in ArcMap or

in a variety of other GIS applications

• PaleoClimate is the next step in developing a

complete picture of the geology for an age

How does it relate to PaleoGIS?

Paleo Process

Basic Geosciences & Geophysics

Lithofacies

Paleoclimate

Paleogeography

Model-based Analysis

Plate Tectonic Model

• PaleoClimate offers rapid cycle & iterative analysis

• Not intended to replace robust Global Circulation Modelling performed on supercomputers

• Geoscientists can quickly explore a wide variety of factors and fine tune assumptions

• Supports first pass screening activities

• Validate the need to invest in more sophisticated and costly climate analysis

Parametric Approach

Configure up to 45 additional parameters to finely tune assumptions for an age

●Axial tilt●Western intensification●Coriolis deflection●Paleography values●Effective latitude●House shift

Additional Configuration

Sample Outputs

• Batch processing tool for the Paleo suite

• Command line executable

• Multiple PaleoGIS or PaleoClimate jobs in series

• Driven by a single XML configuration file

• Simple to run from any scripting language

What is PaleoRun?

• Reconstruction• Multi-reconstruction• Animation• Point Path Visualization• Instantaneous motion• Azimuth & Rate vs Time• Climate Modelling • Modify Metadata• Add Layers and Symbolize

What can PaleoRun do?

• To reconstruct supplementary datasets from third-party vendors

• To execute a large number of jobs, such as when new plate model data is received

• To run one or more long-running jobs, such as large raster reconstructions

• To schedule jobs through the Windows Task Scheduler

Common Scenarios

• Script a series of jobs with DOS scripting tools

• Run a series of jobs as a single batch

• Use outputs from one job as inputs to another

• Schedule scripted jobs to run at regular intervals

• Schedule long-running jobs overnight or over the weekend

• Re-run job scripts many times with consistent results
