X-TRACK-L2P Coastal along-track sea level anomalies

The dataset provides Along-track Sea Level Anomalies over 23 zones for 6 temporal time series: TP+J1+J2+J3, TPn+J1n+J2n, ERS1+ERS2+ENV+SRL, GFO, S3A, HY2A. The Sea Level Anomaly time series have been computed with the X-TRACK processing system (developed at LEGOS) starting from the Level 2 Plus (L2P) products distributed by Aviso+. The altimetry corrections applied are those provided in this product. See the details of the L2P processing on the dedicated product page on Aviso+ https://www.aviso.altimetry.fr/en/data/products/sea-surface-height-products/global/along-track-sea-level-anomalies-l2p.html.

Arctic Ocean gridded and along-track sea level anomaly maps

Pierre Prandi
The dataset provides gridded and along-track sea level anomaly data for the Arctic Ocean. These data are based on the combination of three radar altimetry missions: CryoSat-2, Sentinel-3A and SARAL/AltiKa

Along-track SGDR+ Ice Sheet product for SARAL/AltiKa mission

Jeremie Aublanc
SGDR+ Ice Seet products are available on one year (Oct 2018 to Nov 2019) for SARAL/AltiKa mission. It contains additional variables such as ice sheet elevation, a dedicated slope correction, using a relocation method of the altimetry measurement in order to deliver a product dedicated to ice sheet surfaces. SARAL orbit covers high latitudes up to +/-81.5deg, providing valuable information of the Earth’s polar cryosphere

Gridded Sea Level Heights and velocities with Multiscale Interpolation

Maxime Ballarotta & Clément Ubelmann
The dataset provides gridded sea level anomaly and derived variables. These data are based on the combination of radar altimetry missions. The maps are computed thanks to the Multiscale Interpolation Ocean Science Topography (MIOST) (1/10°x1/10° on cartesian grid)

OHC/EEI from space

The OHC-EEI product results from the space geodetic approach. It contains 2D grids of ocean heat content variations. It also provides the temporal time series of global heat content change from which the Earth energy imbalance time series is derived. Variance-covariance matrices are also delivered and characterise the uncertainties of errors on all global mean time series. See the technical documentation available on the landing page for details.

MSS Combined SIO/CNES_CLS2015/DTU15

Mean Sea Surface Height over the reference time-period [1993, 2012]. This MSS was deduced from the combination of 3 different MSS reference fields over the ocean: - the SIO MSS (Sandwell et al, 2017) was used over the open ocean. - the MSS CNES_CLS15 (Pujol et al, 2016) was used in coastal areas (less than 30km to the coast) and Antarctic region. - the MSS DTU15 (Andersen et al, 2016) was used in Arctic region...

Analysis of the Sentinel-6A Michael Freilich L2P-L3 Sea Level Anomaly SAR-LRM bias correction

Cécile Kocha, Marie-Isabelle Pujol, Pierre Prandi, Emeline Cadier, Sabine Philipps, Gérald Dibarboure, Christophe Maréchal & Christophe Jouan
A bias correction (inter_mission_bias) is computed and applied to L2P Sea Level Anomaly to insure the continuity between Jason-3 and Sentinel-6A MF missions. For Sentinel-6A MF a technical note details the model implemented and its impacts over sea level anomaly.

Atlantic OHC from space

The OHC product results from the space geodetic approach also called “altimetry-gravimetry” approach. This file contains variables as 3D grids of ocean heat content anomalies at 1x1° resolution and monthly time step. Error variance-covariance matrices of OHC at regional scale and annual resolution are also provided. See Experimental Dataset Description for details.

Antarctic Ocean gridded sea level anomaly maps

Pierre Veillard
The dataset provides gridded sea level anomaly data for the Antarctic Ocean. These data are based on the combination of three radar altimetry missions: CryoSat-2, Sentinel-3A and SARAL/AltiKa

Wave experimental products: along-track significant wave height 5Hz

Wave Experimental products: along-track significant wave height 5Hz for altimetry missions. This product has been computed in the frame of the WAVE TAC (Thematic Assembly Center) of the Copernicus Marine Service from Level2+ CNES products.

Gridded Sea Level Heights and velocities with Multiscale Interpolation combining altimetry and drifters

Maxime Ballarotta, Clément Ubelmann, Pierre Veillard, Pierre Prandi, Hélène Etienne, Sandrine Mulet, Yannice Faugère, Gérald Dibarboure, Rosemary Morrow & Nicolas Picot
The dataset provides gridded sea level anomaly and derived variables. These data are based on the combination of radar altimetry missions, drifters and Arctic leads products. The maps are computed thanks to the Multiscale Interpolation Ocean Science Topography (MIOST) (1/10°x1/10° on cartesian grid)
