In the process of developing a new stream temperature model, I noticed some odd seasonal error spikes in mountainous watersheds. It turns out that stream temperature seasonality has some distinct patterns that aren't captured in the typical annual formulation (a sinusoid with a period of one year): in most streams, the spring is colder, summer warmer, autumn colder, and winter warmer than you'd expect from a sine curve.

I'm happy to share that our paper introducing "A machine learning model for estimating the temperature of small rivers using satellite-based spatial data" is out in Remote Sensing of Environment. We developed the model to quickly estimate monthly mean stream temperatures for ungauged basins throughout the contiguous US using minimal data, built for fast, large-scale analyses.

#Introduction

Hello world,
I'm a hydrologist working on large-domain (contiguous US) stream temperature modeling and forecasting with an emphasis on ungauged watersheds, often using remote sensing data products. I also dabble in hydraulic modeling and maintain several open-source packages for stream temperature analysis/modeling and HEC-RAS automation.
