Net Primary Productivity for Bavarian Forest National Park

Net primary productivity (NPP) refers to a complex set of processes in which plants produce biomass by converting solar energy, carbon dioxide, and water (Roy et al., 2001). The primary productivity of vegetation acts as an entry point of atmospheric carbon into the terrestrial ecosystem. NPP is an effective indicator for monitoring forest health and stand age (He et al., 2012). NPP is an essential indicator of resource utilization, ecosystem health, and biosphere carbon fluxes (Cao et al., 2004). NPP can also be used as an indicator to investigate the impact of an extreme climatic event like drought on the ecosystem (Lai et al., 2018; Nanzad et al., 2021). Net Primary Productivity is also considered a remote sensing biodiversity product by the remote sensing and ecology communities (Skidmore et al., 2021). The NPP products for the Bavarian Forest National Park on a monthly basis are generated under Showcase. 4, pilot 4.3. myVARIABLE of the e-shape project, which commits to the biodiversity conservation requirements, inter alia, and assesses the status and trends of biodiversity. In this context, GEO BON, one of the flagships of GEO, is developing the framework of the Essential Biodiversity Variables (EBVs). The EBVs are a minimum set of complementary measurements that capture major dimensions of biodiversity change and are produced by integrating primary observations (from, e.g., in-situ monitoring or remote sensing) in space and time.
