Universal Atmospheric Model & Weather Analysis System

This project predicts planetary temperatures and compares weather patterns across Earth, Mars, and exoplanets using machine learning and a standardized scoring system.

Quick Start

python main.py

What This Does

The system trains machine learning models on Earth and Mars atmospheric data, then uses them to predict temperatures for exoplanets and hypothetical worlds. It scores weather patterns using a 6-dimensional rubric (0-100 scale) and compares all planets with unified metrics.

Model Performance

Test results show strong accuracy:

  • Mean Absolute Error: 5.01°C
  • Root Mean Square Error: 6.17°C
  • R² Score: 0.9421
  • Cross-Validation R²: 0.92 (±0.12)

The model performs well across both Earth and Mars temperature predictions.

Results

Planet rankings based on weather scores (0-100):

Rank Planet Score Habitability Classification
1st Earth 89.8/100 100/100 EXCELLENT
2nd LHS 1140b 68.5/100 27.2/100 GOOD
3rd TRAPPIST-1e 65.1/100 19.3/100 GOOD
4th Proxima Centauri b 64.3/100 25.5/100 GOOD
5th GJ 1214b 47.7/100 19.1/100 MODERATE
6th Mars 28.0/100 5.0/100 POOR

Earth ranks highest with perfect habitability. Exoplanets show cold temperatures (-35°C to -69°C) and limited habitability potential.

Usage

Basic Analysis

# Complete weather analysis for all planets
python run_weather_analysis.py

# Quick analysis without visualizations
python run_weather_analysis.py --quick

# Show current results summary
python run_weather_analysis.py --summary

This generates weather scores (0-100) for Earth, Mars, and 4 exoplanets, plus visualizations and detailed analysis reports.

Missing Data Handling

  • Humidity: defaults to 0 (like Mars) if omitted
  • Planet: uses Mars as analog for calculations if omitted
  • Unknown months: mapped to standard month names
  • Unknown planets: mapped to Mars category for encoding

API Reference
