Howard W. Barker

Research Scientist - Improving Climate and Weather Prediction Models

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to improve climate and weather prediction models

  • Application of satellite data to improve the representation of clouds and radiative transfer in large-scale atmospheric models
  • Development of radiative transfer models for use in large-scale models; both climate and weather
  • Simulation of satellite measurements that are aimed at remote sensing of clouds
