This image shows a scenic desert landscape filled with various types of cacti, including large saguaro cacti and clusters of prickly pear. The terrain is sandy with a visible dirt path winding through the vegetation. In the background, hazy blue mountains rise against a clear sky, and sparse desert trees and shrubs are scattered throughout the scene.

Vapour-Pressure Deficit Workshop

April 25 & 26, 2024 | Fort McDowell, AZ

Introduction

Assessing the relative importance of soil moisture vs. VPD as controls of C cycling in terrestrial ecosystems.

This workshop will be focused on high-level scoping/planning around the topic of VPD, with some preliminary data analysis. A few synthetic “state-of the field” talks are also planned. Subsequent meetings may be planned in the future based on workshop outcomes.
