Drought poses significant challenges to agricultural productivity and water resource sustainability in Henan Province, emphasizing the need for effective monitoring approaches. This study investigates suitability of TRMM 3B43V7 satellite precipitation product drought assessment, based on monthly data from 15 meteorological stations during 1998–2019. Satellite-derived was compared with ground-based observations, Standardized Palmer Index (SPDI) calculated determine optimal timescale. Statistical metrics, including Nash–Sutcliffe Efficiency (NSE = 0.87) Pearson correlation coefficient (PCC 0.88), indicate high consistency between ground measurements. The 12-month SPDI (SPDI-12) found be most capturing historical variability. To support integrated management, a regionally adaptive framework is recommended, balancing demands ecosystem stability through tailored strategies such as enhanced irrigation efficiency humid regions ecological restoration arid zones. These findings provide foundation implementing an operational response system Province.
