canVODpy: An Open Python Ecosystem for GNSS-Transmissometry Canopy VOD Retrievals

  • 1. TU Wien, Department of Geodesy and Geoinformation, Climate and Environmental Remote Sensing CLIMERS Research Unit

Description

canVODpy is the central community-driven software suite for GNSS-Transmissometry (GNSS-T), providing the core ecosystem for deriving and analyzing canopy Vegetation Optical Depth (VOD) from GNSS signal-to-noise ratio (SNR) observations.

The package provides modular sub-packages for RINEX and SBF data reading, auxiliary data handling (SP3/CLK and broadcast ephemeris), hemispheric grid operations, Icechunk-based versioned storage, visualization, and VOD calculation algorithms, all tied together by Pydantic-validated configuration and a pipeline orchestrator.

VOD is a proxy for vegetation biomass and fuel moisture content derived from L-band microwave signals that penetrate the entire canopy — invaluable for monitoring forest health, carbon stocks, and drought stress.
