Postdoctoral Fellow
- Affiliation: UMass Amherst
My work focuses on the advancements and applicability of Synthetic Aperture Radar (SAR) polarimetric parameters to estimate soil moisture over croplands. In my work, I have devised a novel methodology to estimate soil moisture over croplands solely using dual-pol GRD SAR data. The advantages of this method include continuous monitoring of soil moisture over a larger scale at higher resolutions. Besides, I have also developed a novel methodology to estimate soil moisture using full and compact polarimetric SAR data. On the other hand, monitoring and quantifying vegetation content directly helps in better estimation of soil moisture. In this regard, I have developed different vegetation descriptors for dualpol GRD SAR data. Besides, these descriptors are also capable of estimating crop biophysical parameters. These techniques are successfully implemented using Amazon Web Services (AWS), Google Earth Engine (GEE) and Google Colaboratory (Google Colab). These novel techniques and strategies might be helpful to develop operational agricultural crop monitoring platforms through the Joint Experiment for Crop Assessment and Monitoring (JECAM) international research network as well as upcoming satellite missions. My career objective is to obtain a researcher position in the field of remote sensing application to agriculture to associate myself with a progressing science and the nation. Besides, I want to put my expertise to the best use for the remote sensing and agricultural community, as well as widening my technical spectrum.
