The former Arsenal captain has joined Barca on a free transfer after he was released from his contract last night.
As Aubameyang was officially a free agent, the striker was cleared to sign for Barca after the midnight deadline fell in Spain.
Mundo Deportivo says the striker will be paid €5,000-a-week for the remainder of this season to fit under the club's wage cap.
Barca will then up Aubameyang's terms from next season. His Barca deal will run to 2023.
