Vicarious calibration of MERIS over dark waters in the near infrared

After a selection of MERIS and CIMEL data we finally obtained 8 days for the calibration task-about 10% of the initial dataset. We achieved a match-up analysis at 6 MERIS wavelengths, from 884 nm to 664 nm, in the near infrared (NIR). Results show an agreement between the onboard calibration and our method within 1.5% in the NIR which falls in the expected accuracy of the two methods.
