摘要

•NIRvP performed well with GPP across most biomes and climate zones.•The positive correlation between ρNIR and LUE enhanced the NIRvP-GPP relationship.•NIRvP failed to track GPP for some climate zones with different seasonal meteorological patterns.•Both APAR and ρNIR contributed to the NIRvP-GPP relationship.
