I had lost my camera which was very important to me. A Good Samaritan picked it up, left a note between my car's windshield, we communicated via phone, and today we met and I received the camera back to me. Thank you so much Philips 🇺🇸

Hydrology Paper of the Day @rarakihydro.bsky.social on global patterns of water utilization by vegetation: soil, precipitation, and plant processes; leaf area, dry conditions and landscapes; ecological processes and differences between woodlands, savannas and grasslands; and identifying thresholds.

Ryoko Araki @rarakihydro.bsky.social · Jul 29

Co-authored paper is now available at Nature Ecology & Evolution! We applied the nonlinear soil moisture loss model, which we published last month in GRL (Araki et al., 2025), to in-situ field sensor data to reveal emergent patterns of water competition.

Hydrology Paper of the Day @rarakihydro.bsky.social on a model of soil moisture loss that utilizes a nonlinear function: model fitting to SMAP remote sensing data; an examination of global-scale patterns; how aridity, sand fraction and landcover affects outputs; and the role of evapotranspiration.

Ryoko Araki @rarakihydro.bsky.social · Jun 3

My 2nd PhD chapter is out! Soil drying speeds encode the signature of evapotranspiration. Using SMAP data, we demonstrated that, introducing nonlinearity in a traditional soil model help capture aggressive vs conservative vegetation water consumption.

The nonlinear model is more dynamic, continuous than linear model, and potentially more expressive of complex ecohydrologic processes involved.

Today we were in the Re della Pietra #catchment
danielepenna.wixsite.com/redellapietra.
We installed a new #weather station and showed the site to some private #stakeholders.

And this little paper came out right today.
