geeSEBAL is a open-source implementation of Surface Energy Balance Algorithm for Land (SEBAL) using Google Earth Engine (GEE). geeSEBAL is available in both Javascript and Python API.
A web application is also available (https://etbrasil.org/geesebal).
You need an account in GEE (https://earthengine.google.com/).
