GB/T 41281-2022

This standard specifies methods for validating the accuracy of remote sensing products that measure photosynthetically active radiation (PAR), which is critical for vegetation and crop growth monitoring. It is applied in the fields of agriculture, forestry, and ecology, where satellite-derived PAR data must be verified against ground-based measurements to ensure reliability for applications like yield estimation and carbon cycle modeling. The standard provides a framework for quality assessment in remote sensing product validation, particularly for users of Chinese satellite data such as Fengyun and Gaofen series.
