Product processing is performed from Level 1 to Level 3, and is reprojected on a regular square grid format. Data are temporally aggregated and provided as daily, 8 day and monthly products. The "Basic" version of the ODATIS MR product includes data from the MODIS sensor processed with the "NIR/SWIR" atmospheric correction method (Wang and Shi, 2007), as well as data from the MERIS and OLCI-A/B sensors processed with the Polymer atmospheric correction (Hygeos, https://www.hygeos.com/polymer). List of available parameters for each sensor: • MODIS : NRRS555, CHL-OC5, SPM-G, CDOM, T-FNU, SST-NIGHT • OLCI-A/B / MERIS : NRRS560, CHL-OC5, SPM-G, CDOM, T-FNU CDS-AVISO accepted AVISO aviso@altimetry.fr pointOfContact CDS-AVISO distributor CNES funder ACRI-ST originator https://sextant.ifremer.fr/geonetwork/srv/api/records/8f3a1300-a1ce-4461-b463-d03bf58167d5/attachments/l3m_20200401-20200430_france_03_olb_chl-oc5-po_mo_00.png CHL-OC5 [mg.m-3], ODATIS-MR Level-3 OLCI-b monthly product, Polymer atmospheric correction, 2020-04-01 to 2020-04-30.
