The project "Artificial intelligence and semantics of Earth observation data for the establishment of the Valencia Anchor Station as a supersite of the CEOS LPV program" (ASOTVAS) is finished. The initiative has dedicated 3 years of work, from its beginning in September 2021 until August 2024, to collect data such as biophysical parameters of vegetation, soil moisture, emissivity, surface temperature, etc., with the aim of enriching satellite observations using artificial intelligence (AI) and data semantics in relation to the Copernicus and Committee on Earth Observation Satellites - Land Product Validation (CEOS LPV) programs.
The Valencia Anchor Station is a meteorological station located in the Plana de Utiel-Requena region, representative of an area of about 100 square kilometers and has different sensors capable of taking measurements such as radiation fluxes, soil moisture, temperature and biophysical parameters of the vegetation, among other elements.
At this site, ASOTVAS has employed AI and data semantics algorithms on data collected in the area, both in situ and remotely sensed measurements, to provide innovative technologies to enrich satellite observations freely and openly available through the Copernicus program of the European Commission and the European Space Agency, among others.
The initiative also seeks to offer the facility to the international scientific community specialized in Earth Observation as a supersite in the framework of the CEOS LPV, ICOS (Integrated Carbon Observation System), etc. programs, by providing reference measurements and integrated products in the area of the season's own variables.
CEOS LPV is a subgroup that coordinates the quantitative validation of satellite products. It focuses on intercomparison and standardized validation of products from different satellites, algorithms and agencies.
As for the Copernicus Program, it makes available to the scientific community global data from its six Earth Observation satellites (Sentinels), each focused on a specific topic, and is responsible for seeking information on the Earth and its environment for the benefit of the public. It offers information services based on Earth Observation satellite and ground-based data through the GBOV project (Ground-based Observations for the Validation of Copernicus Land Products).
In addition, ICOS, a European-wide greenhouse gas research infrastructure, produces standardized data on greenhouse gas concentrations in the atmosphere, as well as on carbon fluxes between the atmosphere, land and oceans.
