Detailed Information

SATROMO consists of python code with ETL functionalities to operationally generate and provide AnalysisReadyData and indices from satellite sensors

# **SATROMO: Satellite Data for Drought Monitoring** **SATROMO** (*Satellite Data for Drought Monitoring – SAtellitendaten fürs TROckenheitsMOnitoring*) is an automated geospatial data processing system that generates analysis-ready satellite products specifically designed for drought monitoring across Switzerland. *** ## **What SATROMO Does** SATROMO transforms raw satellite imagery into valuable environmental insights through a fully automated processing chain: * *Processes* **Sentinel-2** satellite data using **Google Earth Engine's** powerful cloud computing platform * *Generates* multiple specialized products for **vegetation health** and **drought assessment** * *Publishes* data daily to accessible platforms for **researchers**, **policymakers**, and the **public** * *Maintains* a complete archive of **historical data** for trend analysis *** ## **Key Products** SATROMO produces four primary product types that help monitor Switzerland's vegetation health and drought conditions: * **Surface Reflectance** *Description:* Cloud-free, terrain-corrected satellite imagery *Update Frequency:* **Daily** *Use Case:* Base data for environmental analysis * **Vegetation Health Index** *Description:* Comprehensive vegetation stress indicator *Update Frequency:* **Weekly** *Use Case:* Drought early warning * **NDVI Z-Score** *Description:* Statistical vegetation anomaly detection *Update Frequency:* **Bi-monthly** *Use Case:* Identifying unusual vegetation patterns * **NDVI Difference** *Description:* Vegetation change analysis *Update Frequency:* **Bi-monthly** *Use Case:* Monitoring vegetation dynamics *** ## **How It Works** SATROMO operates as a **serverless**, automated system that runs without manual intervention: * **Data Collection (22:00 UTC daily):** The system checks for new satellite data and initiates processing * **Smart Processing:** Advanced algorithms remove clouds, correct for terrain shadows, and create seamless mosaics * **Quality Control:** Automatic validation ensures only high-quality data reaches users * **Publication (03:00 UTC daily):** Processed data is published to multiple platforms simultaneously The system uses a sophisticated two-stage processing approach: * *Stage 1:* Pre-processes raw satellite data with **cloud masking** and **terrain correction** * *Stage 2:* Generates specialized **indices** and **analysis products** *** ## **Access the Data** All SATROMO products are freely available through: * **Swiss Federal Spatial Data Infrastructure (FSDI)** * **AWS S3 Storage** – Direct access for bulk downloads * **STAC Catalog** – Standardized metadata for easy discovery and integration *** ## **Why SATROMO Matters** * **Early Warning:** Provides timely information for drought preparedness * **Scientific Basis:** Supports research on climate change impacts * **Decision Support:** Helps agricultural and environmental authorities make informed decisions * **Open Data:** Freely accessible to everyone who needs it * **National Coverage:** Complete coverage of Switzerland with consistent quality
