My research primarily inclined towards understanding the dynamics of water resources in Earth’s Critical Zone (CZ), that stretch from the top of canopy to the bottom of groundwater table. I gained expertise in studying the surface and ground water level variability in an agroecosystems using multiple sources of Earth observations (EO), and the source of EO encompasses from satellite to drone-based monitoring of Earth’s hydrosphere. Considering the ground-based data as a critical component of remote sensing studies, a significant part of my reserach involves field observations of land-atmosphere climatic variables that shaped agroecosystems.

Climatic Drivers of Plant Carbon Uptake over Woody Perrenial agroecosystem

My current reserch investigates the variability and potenital climatic drivers of plant carbon uptake over the California agroecosystem. By analyzing ground-observed fluxes from Eddy covariance flux towers, distributed across California’s central valley through T-REX (Tree-Crop Remote Sensing of Evapotranspiration Experiment) and GRAPEX (Grape Remote sensing Atmospheric Profile and Evapotranspiration eXperiment) projects, we are looking forward to address three major objectives: Add after the paper goes in Review (Just to make sure not show anything copyright)
