 ## Intended uses
 
+Contrails (vapor trails from airplanes) are the [number one](https://www.science.org/content/article/aviation-s-dirty-secret-airplane-contrails-are-surprisingly-potent-cause-global-warming) contributor to global warming from the aviation industry.
 We hope that data scientists and researchers focused on reducing contrails will use this model to improve their work. 
 There are current efforts underway to develop models that predict contrails, but one major limiting factor for these efforts is that image labeling is still done by humans (labeled images are needed in order to validate contrail prediction models).
 Labeling contrails in images is a difficult and expensive task - our model helps researchers efficiently segment satellite images so they can validate and improve contrail prediction models.
