To address this need, we introduce SEN2NAIP, a large remote sensing dataset designed to support conventional and reference-based SR model. This dataset is a variation of the SEN2NAIP `synthetic large dataset`. We select Sentinel-2 images that fall within a 30-day window of the corresponding NAIP image. Histogram matching is used to ensure consistent color distribution between the LR and HR images. A manual visual inspection is then conducted to discard any poor-quality images. The LR image is generated following the SEN2NAIPmethodology.
