Overview

What is he best known for?

The fields of study he is best known for:

  • Statistics
  • Meteorology
  • Artificial intelligence

Water content, Remote sensing, Meteorology, Brightness temperature and Data assimilation are his primary areas of study. His work deals with themes such as Soil science, Soil water, Drainage basin, Precipitation and Moisture, which intersect with Water content. His Remote sensing research is multidisciplinary, relying on both Image resolution, Downscaling and Vegetation.

His Meteorology study incorporates themes from Kalman filter and Extended Kalman filter. Jeffrey P. Walker interconnects Surface runoff, Ensemble Kalman filter and Satellite gravimetry in the investigation of issues within Data assimilation. He has researched Radiometer in several fields, including Soil map, Calibration and Biosphere.

His most cited work include:

  • The Global Land Data Assimilation System (2484 citations)
  • A methodology for surface soil moisture and vegetation optical depth retrieval using the microwave polarization difference index (542 citations)
  • Upscaling sparse ground‐based soil moisture observations for the validation of coarse‐resolution satellite soil moisture products (411 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of study are Remote sensing, Water content, Radiometer, Meteorology and Brightness temperature. The study incorporates disciplines such as Image resolution, Downscaling and Vegetation in addition to Remote sensing.

Jeffrey P. Walker spends much of his time researching Remote sensing, Water content, Radiometer, Downscaling and Brightness temperature. His Remote sensing research integrates issues from Mean squared error and Leaf area index. His Water content research includes themes of Moisture, Soil science, Pixel and Vegetation.

His Moisture research incorporates elements of Biosphere, Atmospheric sciences and Groundwater. He has included themes like Soil water, Salinity, Evapotranspiration and Radiometry in his Vegetation study. Jeffrey P. Walker combines subjects such as Image resolution, Calibration and L band with his study of Brightness temperature.

Between 2018 and 2021, his most popular works were:

  • The FLUXNET2015 dataset and the ONEFlux processing pipeline for eddy covariance data (67 citations)
  • The SMAP and Copernicus Sentinel 1A/B microwave active-passive high resolution surface soil moisture product (38 citations)
  • Version 4 of the SMAP Level-4 Soil Moisture algorithm and data product (25 citations)

In his most recent research, the most cited papers focused on:

  • Statistics
  • Artificial intelligence
  • Meteorology

Jeffrey P. Walker mainly investigates Water content, Remote sensing, Synthetic aperture radar, Downscaling and Data assimilation. His specific area of interest is Water content, where Jeffrey P. Walker studies Active passive. His work carried out in the field of Remote sensing brings together such families of science as GNSS applications, Bistatic radar and Brightness temperature.
