ECOSTRESS ET was paired with PSInet predawn and midday leaf water potentials within seven days. Lower ET aligned with more negative water potentials, with significant correlations for 9 of 26 species at midday and 7 of 28 at predawn. Effect sizes varied by functional traits and site, suggesting that ECOSTRESS ET provides a scalable, non-invasive indicator of plant drought stress that complements field measurements and management decisions.</p> <hr> <h2 id="poster-presentation">Poster Presentation</h2> <p>This research was <strong>presented at the 2025 NASA ECOSTRESS Annual Science Team Meeting</strong>.<br> Highlighting the integration of satellite-derived evapotranspiration data with field-measured leaf water potentials to assess drought stress at a global scale.<br> The poster summarizes cross-species analyses showing significant relationships between ECOSTRESS-derived evapotranspiration and plant water potential.</p> <figure style="margin: 2rem 0;"> <img src="Poster.png" alt="Satellite Measurements of Evapotranspiration Predict Plant Water Stress Poster" style="width: 100%; max-width: 1000px; display: block; margin: 0 auto; border-radius: 8px; box-shadow: 0 4px 8px rgba(0,0,0,0.15);"> <figcaption style="text-align: center; margin-top: 1rem; font-style: italic; color: #666;"> Poster presented at the NASA ECOSTRESS Annual Science Team Meeting — demonstrating ECOSTRESS evapotranspiration as a global-scale indicator of plant drought stress. </figcaption> </figure> <hr> <h2 id="download">Download</h2> <p> {download}</p> <p>For more projects and publications, visit my<br> .</p>
