Defensible climate-risk evidence

Model trust for defensible 2050 climate-risk decisions.

Arasense helps cities, infrastructure owners, and climate-risk consultants produce defensible evidence for flood-driving rainfall, heat, and drought. For each location, the platform shows which models earn trust, which models are rejected, and what the trusted models imply for mid-century risk.

Case studies

Evidence from current Arasense workflows

Current examples show how Arasense evaluates climate-model trust, reports mid-century hazard signals, and ranks locations by worsening climate-risk indicators.

Bologna

+14.2% max 1-day rainfall

Full-ensemble projection with 32 of 34 CMIP6 models passing skill screening and 78% trusted-model agreement on increase.

Italian portfolio

Rome ranks highest

Portfolio view ranks cities by worsening flood-driving rainfall signal, with Rome at +19% and Venice at +3% in the sample.

Bari / Puglia

Regional climate-risk application

The same workflow can support local adaptation, infrastructure, and advisory conversations in Puglia.

Scientific Foundation

Research-grounded methods, framed for institutional use

Arasense is built around interpretable model evaluation and transparent evidence generation. The platform connects the Aras Diagram framework with operational geospatial data sources and validation-stage screening workflows.

Model evaluation

Aras Diagram

Structured decomposition of model behavior across bias, variability, and phase alignment, supporting clearer judgement than a single aggregate score.

Climate data

ERA5-Land and CMIP6

Climate diagnostics and projections are framed around established reanalysis and global climate model datasets, with model skill made explicit.

Earth observation

Sentinel-1 evidence

Flood-screening pilots can be compared against satellite-derived evidence windows to document where the workflow performs and where it remains uncertain.

Platform

An analytical console for climate-risk evidence

Arasense combines climate model evaluation, bias-aware interpretation, projection reporting, portfolio screening, and validation-stage flood analytics into one technical stack. The objective is not another generic dashboard. The objective is a more defensible basis for planning, screening, and risk communication.

Climate Intelligence

Compare climate model behavior through Aras Diagram signal decomposition, model-trust tiers, and transparent ranking logic.

Projection Reports

Estimate mid-century changes for rainfall, heat, drought, and scenario differences using trust-weighted models.

Portfolio Screening

Rank locations by worsening hazard signal so teams can see which exposures deserve attention first.

Private Console

The enhanced console is built around spatial decisions

The Arasense console is available through guided demos, pilot studies, and selected collaborations. Teams select climate points and flood-screening regions directly on a map, then generate structured outputs for model trust, projections, portfolio ranking, and validation review.

Map-first workflow

Click, draw, analyze

Set a climate region of interest with one map click, draw flood-screening boxes, and keep the spatial inputs synchronized across forms and reports.

Model trust

Aras Diagram plus trust engine

Score models by bias, variability, and alignment, then surface which models are credible enough to drive projections at the selected location.

Hazard reporting

2050 projections and multi-hazard profiles

Generate mid-century reports for rainfall extremes, heavy-rain frequency, heat, and drought, including SSP2-4.5 vs SSP5-8.5 comparisons.

Flood pilot

Terrain, climate, and Sentinel evidence

Combine hydrological graph structure, climate-driven precipitation features, GNN screening probabilities, and Sentinel-1 validation windows for regional pilots.

Institutions

For teams that must explain climate-risk decisions

Arasense supports public authorities, infrastructure owners, and climate/adaptation consultants that need transparent climate evidence for planning, prioritization, advisory work, or investment-facing communication.

Public and infrastructure

Authorities, utilities, and asset owners

Support resilience planning, regional screening, asset prioritization, and early-stage adaptation decisions with more structured evidence.

Advisory and finance

Consultancies, analysts, and risk teams

Strengthen client deliverables, due diligence workflows, and comparative climate-risk assessments with clearer interpretability.

Approach

Why the approach is credible

Scientific basis
  • Aras Diagram framework for structured climate-model evaluation.
  • Model Trust Engine for location-specific skill tiers and projection weights.
  • Regional and multi-model assessment logic grounded in research practice.
  • Focus on bias, variability, and alignment rather than presentation-only summary scores.
Technical basis
  • FastAPI backend for deployable diagnostics, reports, and API workflows.
  • Map-first console with climate diagnostics, projection comparison, portfolio ranking, and raw JSON validation.
  • Graph neural network flood pipeline currently scoped to validation-stage regional pilots with Sentinel-1 comparison.
Client value

Faster first-pass insight

Arasense is aimed at shortening the path from complex data to a first defensible interpretation, especially where teams need to compare scenarios, rank locations, or communicate uncertainty clearly.

How work can start

Pilot-led engagement

Early collaborations can begin with a geography, asset class, or decision question, then expand into repeatable workflows as the value is demonstrated.

Validation note

Flood outputs are validation-stage screening evidence. They are not a replacement for hydraulic modelling, field validation, local calibration, or engineering-grade flood forecasting.

Use Cases

Focused studies and portfolio workflows

Arasense can support single-location studies, regional screening, and multi-asset portfolio ranking through the same model-trust workflow.

Near-term applications

Regional evidence packs

Example applications include coastal rainfall, flood-driving rainfall, heat-risk screening for infrastructure, and portfolio ranking for advisory teams. View the Bari / Puglia regional application.

Delivery model

Custom pilot, then platform access

Focused pilots and decision-support engagements can expand into live product access and API workflows as needs mature.
