Appraisal of Climate Response to Vegetation Indices over Tropical Climate Region in India

Extreme climate events are becoming increasingly frequent and intense due to the global change. The present investigation aims ascertain nature of climatic variables association with vegetation such as Leaf Area Index (LAI) Normalized Difference Vegetation (NDVI). In this study, impact change respect dynamics has been investigated over Indian state Haryana based on monthly yearly time-scale during time period 2010 2020. A time-series analysis was carried out using MODIS-derived NDVI LAI datasets. spatial mean for all except rainfall (taken sum data compute accumulated rainfall) parameters analyzed study area basis. liaison were assessed at multi-temporal scale basis Pearson correlation coefficients. results obtained from reveals that strong significant relationship cropping months area. contrast, non-cropping months, weakens but remains 0.05 significance level. Furthermore, relative humidity depict positive LAI. On other, negative trends observed in case other limitations viz. saturation values lower sensitivity higher influence aerosol optical depth be much compared NDVI. findings confirmed satellite-derived indices significantly useful towards advancement knowledge about between dynamics.
