A dataset of 30 m/10-day spatio-temporal continuous leaf chlorophyll content of MuSyQ GF-series (2022, China)

High-precision, spatiotemporally continuous LCC products are foundational for accurate carbon cycle modeling on global and regional scales. Currently, international global LCC products have spatial resolutions at the hectometer level, which are insufficient to meet the growing demand for fine-scale detection.

The existing MuSyQ LCC (v01) product offers a spatial resolution of 30 meters; however, its values are affected by clouds and rainfall, resulting in spatiotemporal discontinuities that limit its effective use in high-resolution applications. This study uses the Sentinel-2 MSI data, based on the chlorophyll-sensitive index (CSI) and the Harmonic Analysis of Time Series (HANTS) method, to produce a standardized, spatiotemporally continuous LCC product for China at 30 m/10-day resolution in 2022 as part of the MuSyQ high-resolution series.
