# Climate Risk and Resilience Index - Methodology

## Overview

This section explains how AlphaGeo builds the **Climate Risk and Resilience Index (CRRI)**.

It covers the scoring framework, adaptation logic, climate data pipeline, source data, and how CRRI differs from hazard-only products.

### What this section covers

CRRI combines two views of climate risk:

1. **Physical Risk** — the baseline hazard signal
2. **Resilience-Adjusted Risk** — the likely real-world impact after adaptation and resilience factors are applied

The methodology pages in this section explain how AlphaGeo:

* converts hazard intensity into risk signals
* applies a triple-layer adaptation workflow
* incorporates asset-level remediation measures
* processes climate and geospatial data onto a common scoring grid
* curates the source data behind the model

### Key pages

#### [Methodology: Resilience-adjusted Risk with Triple-layer Adaptation Offset](/methodology/methodology-docs/climate-risk-and-resilience-index-methodology/methodology-resilience-adjusted-risk-with-triple-layer-adaptation-offset.md)

Start here for the core CRRI framework.

This page explains how AlphaGeo moves from physical hazard to resilience-adjusted risk using local adaptation capacity, societal resilience, and asset-level remediation inputs.

#### [Methodology: Remediation Checklist - Quantifying Asset-level Adaptation](/methodology/methodology-docs/climate-risk-and-resilience-index-methodology/measuring-asset-resilience.md)

Use this page to understand the asset-level layer of the model.

It explains how building features and mitigation measures reduce risk by hazard, how the scoring logic works, and how residual risk is capped.

#### [Methodology: Climate Data Processing, Resolution & Downscaling](/methodology/methodology-docs/climate-risk-and-resilience-index-methodology/methodology-climate-data-processing-resolution-and-downscaling.md)

Use this page to understand the data pipeline.

It documents climate model inputs, spatial resolution, H3 processing, per-hazard source layers, and key limitations of the current framework.

#### [Data Sources](/methodology/methodology-docs/climate-risk-and-resilience-index-methodology/data-sources.md)

Use this page to review the underlying datasets.

It summarizes the core risk and resilience sources, coverage, update cadence, and selected references used across the CRRI framework.

#### [AlphaGeo versus the Market: Climate Risk and Resilience Index (CRRI)](/methodology/methodology-docs/climate-risk-and-resilience-index-methodology/alphageo-versus-the-market-climate-risk-and-resilience-index.md)

Use this page to see how CRRI differs from other providers.

It explains the role of resilience-adjusted risk, the Global Adaptation Layer, and AlphaGeo's broader analytics stack.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.alphageo.ai/methodology/methodology-docs/climate-risk-and-resilience-index-methodology.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
