<p>This model archive component contains model weights, inputs, outputs, and performance metrics for the source coarse model for which downscaling was desired. Some methods in Fan et al. (2025b) explore methods for downscaling from this source coarse model, while others explore different uses of these coarse-resolution source data in conjunction with fine-resolution data (see model archive component 2, Model Inputs, for the fine-resolution data).</p> <p>The parent model archive (<a href="https://www.sciencebase.gov/catalog/item/66787f3ed34efbe36238c80a">Fan et al. 2025a</a>) provides all data, code, and model outputs used in the corresponding manuscript (Fan et al. 2025b) to test machine learning (ML) methods for downscaling and multi-scale modeling of stream temperature to combine an ML model and/or input data at coarse spatial resolution with an ML model and/or input data at fine spatial resolution to predict stream temperatures at fine spatial resolution in a watershed.</p> <p>The data are organized into these child items: <li><a href="https://www.sciencebase.gov/catalog/item/6682f4f8d34e57e93663d655"> 1.
