Description

Average annual Gross Biomass Water Productivity (GBWP) for the last three years on record 2017-2019. The annual Gross Biomass Water Productivity expresses the quantity of output (total biomass production) in relation to the total volume of water consumed in the year (actual evapotranspiration).

Annual trend in Gross Biomass Water Productivity (GBWP) changes for the years 2009-2019. Scale of the linear fit of the yearly sum of the GBWP for the whole period. The annual Gross Biomass Water Productivity expresses the quantity of output (total biomass production) in relation to the total volume of water consumed in the year (actual evapotranspiration).

Difference of average annual Gross Biomass Water Productivity (GBWP) for the years 2009-2019 compared to 2017-2019. Areas where the GBWP values might have suffered anomalies in the last 3 years. The annual Gross Biomass Water Productivity expresses the quantity of output (total biomass production) in relation to the total volume of water consumed in the year (actual evapotranspiration).

Net Primary Production (anomalies)

Net Primary Production (average): 0 g/m² - 6 g/m²



Net Primary Production (change): -1 g/m² - 1 g/m²


Net Primary Production (anomalies): -1 g/m² - 1 g/m²

Average of the annual Net Primary Production (NPP) for the years 2017-2019. Net Primary Production (NPP) is a fundamental characteristic of an ecosystem, expressing the conversion of carbon dioxide into biomass driven by photosynthesis.

Source data

Description

Until December 2019 the base input layers (NDVI, albedo, and fAPAR) for the Level 2 (100m) products were derived from the Proba-V satellite. Proba-V was decommissioned in June 2020. From January 2020 onwards the base input layers of NDVI, albedo and fAPAR for level 2 are derived from the Copernicus Sentinel-2 mission.
