EOLAB participates in the Quality Assurance for Earth Observation (QA4EO-2) project

In 2010s, the CEOS WGCV established a CEOS Cal/Val action (cv-12) aimed to evaluate validation supersites. In particular, the action was ‘the evaluation of well-characterized supersites with data continuity prospects for validation purposes that allow for testing products, algorithms, and validation strategies through radiative transfer modelling’.

In response to this CEOS WGCV (cv-12) action, the CEOS LPV subgroup undertook an action (lead by Fernando Camacho, EOLAB) to identify CEOS supersites for land product validation considering additional actions from the GCOS Implementation Plan 2016.

EOLAB will participate in the following tasks:

• Identification of supersites, which must be super characterized (canopy structure and bio-geophysical variables), follow the protocols useful for the validation of satellite land products (at least 3 products) and radiative transfer model approaches. In addition, they must be active at long-term and, if possible, supported by airborne LiDAR and hyperspectral acquisitions.
• The supersites were primarily selected from well-known networks, as National Ecosystem Observatory Network (NEON), Integrated Carbon Observation System (ICOS) and Australian Terrestrial Ecosystem Research Network (TERN) and were complemented with others as Copernicus Ground-based Observations for Validation (GBOV).
• The sites were also ranked according to the global region, representativeness, structural information and by other properties measured in the site.
