The cruiseferry MV Pride of Bilbao is a cruiseferry that was used as a platform for Infrared Sea surface temperature Autonomous Radiometer (ISAR), which collected skin SST data between 2004 and 2010 for the (A)ATSR Validation Campaign. The cruiseferry travelled between Portsmouth, UK and Bilbao, Spain. In September 2010, the ship retired from its service on Portsmouth-Bilbao route. To continue the validation campaign, ISAR was mounted on MV Cap Finistere on the following month.
