## Geo-Benchmark: Open-Source Benchmark for Evaluating LLM Climate Prediction Capabilities

CliDyn team has open-sourced the geo_benchmark framework (MIT license, Python-based) to systematically assess large language models (LLMs) in global climate data prediction tasks. Key features include generating global geographic grids, integrating multi-source geospatial data, and quantifying model accuracy in temperature and precipitation predictions. The project is available on GitHub (https://github.com/CliDyn/geo_benchmark) and was released on June 15, 2026.

## Background & Motivation

LLMs have expanded their capabilities to text generation, code writing, and complex reasoning, but their performance in precise scientific domains like climate science remains under-evaluated. Traditional LLM benchmarks focus on language understanding/generation, lacking standardized tools for scientific computing and geospatial reasoning. Geo-Benchmark fills this gap by providing a framework for assessing LLM performance in climate prediction tasks.

## Project Overview & Core Workflow

Geo-Benchmark is a specialized benchmark for evaluating LLMs' climate prediction performance. Its core workflow includes:
1. Generating global geographic grids (supporting various resolutions)
2. Identifying land coordinates using shapefile data
3. Enhancing location data via multi-source geospatial information integration
4. Querying LLMs for temperature and precipitation predictions
5. Analyzing and visualizing results against real observational data (e.g., ERA5 reanalysis data)

## Technical Architecture & Key Features

The framework's technical highlights:
- **Geographic Grid Processing**: Modular system for flexible grid resolution selection
- **Data Integration**: Combines high-resolution coastline data, DEM, population distribution, and ERA5 data as reference
- **Efficiency**: Batch query mechanism and distributed processing for large-scale global evaluations
- **Analysis Tools**: Spatial RMSE analysis, monthly trend comparison, climate scenario analysis, and regional performance contrast

Tech stack: Python with GeoPandas, xarray, matplotlib/cartopy, PyYAML

## Evaluation Metrics & Methodology

Geo-Benchmark uses multiple metrics to assess LLM performance:
- **RMSE**: Core numerical accuracy metric for comparing predicted vs. observed values (supports single/multi-variable calculations)
- **Spatial Distribution Analysis**: Maps prediction errors to identify geographic regions with systemic biases
- **Time Series Analysis**: Evaluates model understanding of seasonal/climate periodicity
- **Model Comparison**: Supports parallel assessment of multiple LLMs (e.g., GPT series, Ollama-deployed models) for performance contrast

## Use Cases & Applications

The framework serves three main purposes:
1. **Academic Research**: Climate scientists can evaluate LLMs' climate knowledge and identify blind spots in specific regions/phenomena
2. **Model Development**: LLM developers can use iterative evaluations to optimize geospatial and scientific reasoning capabilities
3. **Education**: Helps students understand climate data complexity and AI limitations in scientific prediction

## Limitations & Future Directions

Current limitations:
- **Data Dependency**: Evaluation quality relies on input data quality/coverage
- **Compute Resources**: High-resolution global evaluations require significant computational power
- **Model Interface**: Primarily supports API-based closed-source models and local Ollama deployments

Future plans:
- Expand support for more climate variables (humidity, wind speed)
- Integrate real-time meteorological data streams
- Develop city-level fine-grained evaluation
- Establish a public model performance leaderboard

## Conclusion

Geo-Benchmark represents an important step in extending AI benchmarks to professional scientific fields. By providing a standardized, open-source tool, it helps researchers understand LLMs' capabilities and limitations in climate prediction. As climate change urgency grows, such tools are critical for assessing AI's reliability in supporting climate decision-making.
