Incident irradiance above water and upward radiance below the water surface during L'Atalante cruise ATA03 in the Atlantic Ocean at station 009001

The incident irradiance above water Es (lambda) and the upward radiance just below the water surface Lu (lambda,0-) were measured with Satlantic surface reference (SMSR-SeaWiFS Multichannel Surface Reference) in 13 channels between 412 nm and 700 nm. All measurements were made according to the recommendations of the SeaWiFS validation team (Mueller and Austin 1995). The sampling data rate was 6 Hz.
