Dataset description

The Leaf Area Index (LAI) is a dimensionless quantity that characterizes plant canopies. It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m² / m²) in broadleaf canopies. The LAI values are dimensionless. The GBOV service (Ground-Based Observations for Validation) is a project funded by the European Commission. Its objective is to provide analysis-ready validation data to support the evaluation of Earth Observation products. The core aim of GBOV is to generate upscaled products derived from ground-based measurements. This dataset consists of LAI values extracted from Digital Hemispherical Photographs (DHPs) campaigns over stations located in North America, Europe, Japan and Australia. The DHPs are mostly provided by the following networks: TERN, NEON and ICOS.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
