Caliza™ 3.0

Caliza™ is one of the core computational tools used by CRA to perform nonstationary risk analysis. It is the flagship of CRA software products.

The role of Caliza™ and its predecessor, XTREND, in the study of climate risk, has been frequently noted in professional journals which have a high impact on the climate change industry. See right for examples.

CRA can easily custom-tailor Caliza™ to reflect your specific requirements for sensitivity analysis. Consider, for example, how sensitive flood risk estimates are to the existence or nonexistence of reservoirs on a river.

The nominal list price is net 900 EUR (plus VAT). Contact CRA for your personal Caliza™ proposal, pricing, or any other information. Here is the contact form.
