lithium detection with satellites

Sentinal-1

The Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather. sentinel-1

COSMO+SAOCOM

The main difference between the two sensors is the wavelength: 3 cm for COSMO-SkyMed X-band and 23 cm for SAOCOM L-Band. This translates in the fact that while X-band can detect even slight details, L-band is suitable to observe larger objects which would result unclear with X-band. Combining the two is possible to monitor both geometrical objects and small details. e-gos.it

“The Alaska Satellite Facility provides production, archiving and distribution to the scientific community of SAR data products and tools from active and past missions, including the June 2013 release of newly processed, 35-year-old Seasat SAR imagery.”
