📊 Examples of potential applications

  • Mapping of sea surface salinity and its variability (estuaries and coastal waters).

📏 Range of flight height and captured zone width (m)

Typical altitudes: 2600 m, 700–1100-m-wide beam footprints spanning a 5-km swath.

📏 Spectral Range (nm)

8000–14,000-nm and 9600–11,500-nm.

📏 Spatial Resolution (m)

1-km resolution.

Tip

Benefits

  • Clouds do not block the microwave observations, but they do cause gaps in the IR observations, which are filled by interpolation.

Note

Limitations

  • In-situ data are usually collected to complement surveys that use airborne salinity sensors.
