摘要：
This study used 18 years (2001-2018) of Moderate Resolution Imaging Spectroradiometer-based Enhanced Vegetation Index products over Jharkhand state to extract phenology metrics based on Harmonic Analysis of the Time-Series algorithm. Results revealed that majorly Start of Season (SoS) occurred during April to June, End of Season (EoS) during December to February, and Peak of Season (PoS) during August to September in the forested areas. Trend analysis of SoS, PoS and EoS revealed advancement in 3891 Km(2), 2627 Km(2), and 3486 Km(2) and delay in 5447 Km(2), 5953 Km(2), and 8265 Km(2) of the study area.
