Abstract
En 中文
• Improved intra-annual dynamics detection in waterlogged wetlands. • Validated and compared our framework against four baselines across 9915 sites. • Achieved comparable spatial delineation accuracy and the highest temporal accuracy. • Released broadly calibrated OPtical TRApezoid Model (OPTRAM) coefficients. • Assessed ten vegetation indices and nonlinear parameterization effects on OPTRAM.
