      # **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
