Experimental Targeted Observing Guidance in Support of TCS-08 and T-PARC

Sharanya J. Majumdar (UM/RSMAS/MPO)

Introduction

This website contains experimental adaptive sampling (or targeting) guidance, aimed at reducing the wind error variance in numerical forecasts of tropical weather within the red rectangular region. The 'warmer' areas in the Ensemble Transform Kalman Filter (ETKF) guidance are recommended as best for sampling.
