Surface Water and Ocean Topography (SWOT)

The MASS instrument package was installed on NASA Johnson Space Center’s newly acquired Gulfstream V aircraft to assess sensor performance for potential future SWOT Calibration and Validation missions. Five science flights were carried out over a test site approximately 350km due west from the operations base of Monterey Regional Airport in late March and early April of 2019, with additional test and calibration flights conducted over land during the same period.


Coincident calibration flights were conducted approximately 350km west of Monterey, California.


Pilot calibration and validation flights were conducted in March and April of 2019. Actual SWOT calibration and validation flights were conducted in April and June of 2023.
