System requirements

• PACE has been developed in Windows 10 64-bit.
• PACE is an Add-in for ArcGIS and requires either ArcGIS 10.4.1+ Desktop or ArcGIS Pro 3.2+ to run. See www.esri.com/products for more details
• The NAMEIII atmospheric model that PACE incorporates is a highly complex numerical code and has to be run repeatedly for many different meteorological conditions and overall run times can take days for a complex situation involving a large area, long duration release and many radionuclides. Therefore, a powerful multi-processor workstation is preferred for PACE.
• PACE has significant spatial input data requirements and generates greater quantities of output data. The default run-set for the UK is nearly 1 GB and just one year of NWP data for NAMEIII at 10-11km resolution could be 30-40 GB when uncompressed. Finer resolution datasets will require more storage. A single output database could in extreme cases be 10 or more GB. Therefore, a large local drive is desirable as well as access to a large server for backup and long-term storage.

Detailed specifications for specific versions of PACE can be found on the resources page of this website.

Development

Development of PACE was undertaken by UKHSA.

NAMEIII was developed by Met Office and is available for use within PACE on a special license.
