Research Project: Probabilistic Sensor Deployment

Location: Horticultural Crops Research

Project Number: 2072-22000-041-18-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 15, 2017
End Date: Sep 14, 2019

Efficiently sense the agriculture environment with unprecedented spatial extent and breadth of measurements using a wide range of sensing strategies.

A gridded array of Turbulence and Energy Assessment Meteorological Stations (TEAMS) will be placed within each test location, and data will be compared to National Oceanic Atmospheric Administration forecasts and current weather interpolation (e.g. We will use Optimal Experimental Design which applies Bayesian statistics to optimize the siting of low-cost sensors within a field on an 80-meter grid. In an addition to the mobile TEAMS, each site will include a fixed 10-meter tower with sensors to quantify vertical variability of turbulence, carbon and vapor flux, and the surface energy balance. These high-cost, high-quality sensors will provide validation data for the 80-meter downscaled products and model estimates of the transport of heat, moisture, and momentum. Validation efforts will use a combination of field experiments and numerical simulations.
