🌿 Overview

The SMM Toolkit detects and analyzes soil moisture drydowns and computes short-term soil moisture memory timescales (Ts) from time series of soil moisture and precipitation.

Key features:

• 📈 Automatic drydown detection
• 🧪 Exponential curve fitting and R² filtering
• 🕒 Short-term timescale (Ts) computation for positive increments
• 📊 Plotting and result export
• 🧰 YAML-based configuration for reproducible runs
• ⚡ PyPI installable & CI tested

🧰 Installation

You can install the package directly from PyPI:

pip install smm-toolkit
