Skin Sea Surface Temperature data from the (A)ATSR Validation Campaign by ISAR. The prime objective of the (A)ATSR mission is to return accurate measurements of the global sea surface temperature. To ensure the accuracy of the measurement, there have been joint efforts to validate the data. One of these efforts is the (A)ATSR Validation Campaign which involves the deployment of the the Infrared Sea surface temperature Autonomous Radiometer (ISAR). The ISAR is designed to measure accurate and reliable skin sea surface temperature, with automated system of data collection, and its own protection from severe weathers. Data come from the ISAR mounted on cruiseferries MV Pride of Bilbao (2004-2010) and MV Cap Finistere (2010-2012) and were collected continuously throughout the cruises unless severe weather conditions required the instrument to be protected, which results in the prevention of the data collection.

The Infrared Sea surface temperature Autonomous (ISAR) measured the skin sea surface temperature for the (A)ATSR Validation Campaign. The ISAR was on-board MV Pride of Bilbao measured the skin sea surface temperature between Portsmouth, UK and Bilbao, Spain from 2004 to 2010. As MV Pride of Bilbao went out of service on mid-late 2010, the instrument was moved to MV Cap Finistere which travelled between Portsmouth, UK and Bilbao, Spain or Santander, Spain. The instrument was on-board the new platform between 2010 and 2012.
