# 🏜️ DESERTAS PROJECT SUMMARY

## 📋 Project Overview

**DESERTAS** (Desert Emission Sensing & Energetic Rock-Tectonic Analysis System) is a comprehensive framework for decoding geogenic gas emissions, tectonic pulse detection, and pre-seismic geochemical forecasting in hyperarid cratons. The framework introduces the first mathematically rigorous, AI-integrated multi-parameter system for quantifying desert gas emissions through the **Desert Rock-Gas Intelligence Score (DRGIS)**.
