This dataset provides a Climate Data Record of Sea Ice Thickness for the Northern Hemisphere polar region, derived from the SIRAL (SAR Interferometer Radar ALtimeter) instrument on the CryoSat-2 satellite at Level 3C (L3C). This product was generated in the context of the ESA Climate Change Initiative Programme (ESA CCI) by the Sea Ice CCI (Sea_Ice_cci) project.It provides monthly gridded sea ice thickness data on a Lambeth Azimuthal Equal Area grid for the period November 2010 to April 2017. Data are only available for the NH winter months, October - April.

Version 0.1 of the product contains three files:1) NetCDF file containing the surface elevation change grids from AltiKa and from Cryosat-2 (for comparison) for 2013-2017 and their associated errors2) PNG plot of the surface elevation change from AltiKa3) PNG plot of the surface elevation change from Cryosat-2
This data set is part of the ESA Greenland Ice sheet CCI project. The data set provides surface elevation changes (SEC) for the Greenland Ice sheet derived from SARAL-AltiKa for 2013-2017. This new experimental product of surface elevation change is based on data from the AltiKa-instrument onboard the France (CNES)/Indian (ISRO) SARAL satellite. The AktiKa altimeter utilizes Ka-band radar signals, which have less penetration in the upper snow. However, the surface slope and roughness has an imprint in the derived signal and the new product is only available for the flatter central parts of the Greenland ice sheet.The corresponding SEC grid from Cryosat-2 is included for comparison. The algorithm used to devive the product is described in the paper âImplications of changing scattering properties on the Greenland ice sheet volume change from Cryosat-2 altimetryâ by S.B. Simonsen and L.S. SÃ¸rensen, Remote Sensing of the Environment, 190,pp.207-216, doi:10.1016/j.rse.2016.12.012. The approach used here corresponds to Least Squares Method (LSM) 5 described in the paper, in which the slope within each grid cell is accounted for by subtraction of the GIMP DEM; the data are corrected for both backscatter and leading edge width; and the LSM is solved at 1 km grid resolution (2 km search radius) and averaged in the post-processing to 5 km grid resolution and with a correlation length of 20 km.

Files are provided in both NetCDF (.nc) and ASCII Gravsoft (.gri) format, as well as .png images. In ascii gravsoft format the data are stored rowâwise in EâW rows, from N to S, headed by a twoâline label defining coordinate limits and projection. This format is the simplest possible ASCII grid format. Unknown values are flagged by 9999. The grid label for the CCI data is:â3350000. â650000. â650000. 850000. 5000. 5000. (this is N1, N2, E1, E2, dN, DE in meter)â70 â45 (minus reference latitude, central meridian in degrees)The CCI data grid contains a total 541 x 301 points. First data value in file is thus the NW cormer (N = â650 km,E = â650 km) and last value the SE corner (N = â3350 km, E = 850 km). Stereographic projections have by default (0,0) at the North Pole.The data use a Polar stereographic projection, WGS84 ellipsoid, with a reference latitude of 70N, and central meridian of 45W
This data set is part of the ESA Greenland Ice sheet CCI project. The data set provides surface elevation changes (SEC) for the Greenland Ice sheet derived from satellite (ERSâ1, ERSâ2, Envisat and Cryosat) radar altimetry. The ice mask is based on the GEUS/GST land/ice/ocean mask provided as part of national mapping projects, and based on 1980âs aerial photography. The data from ERS and Envisat are based on a 5âyear running average, using combined algorithms of repeatâtrack (RT), alongâtrack (AT) or crossâover (XO) algorithms, and include propagated error estimates. It is important to note that different processing algorithms were applied to the ERSâ1, ERSâ2, Envisat and CryoSat data; for details see the Product User Guide (PUG), available on the CCI website and in the documentation section here. For ERSâ1, the radar data were processed using a crossâover algorithm (XO) only. For ERSâ2 data and Envisat data in repeat mode, a combination of RT and XO algorithms was applied, followed by filtering. For acrossâmission (i.e. ERSâ2âEnvisat) combinations, and for Envisat operating in a drifting orbit, an AT and XO combination was applied (the difference between RT and AT algorithms is that AT use reference tracks and searches for data in the vicinity of this track). For CryoSat data a binning/gridding and plane fit method has been applied, following by weak filtering (0.05 degree resolution).

As part of the European Space Agency's (ESA) Sea Level Climate Change Initiative (CCI) project, a number of oceanic indicators of mean sea level changes have been produced from merging satellite altimetry measurements of sea level anomalies. The oceanic indicators dataset consists of static files covering the whole altimeter period, describing the evolution of the project's monthly sea level anomaly gridded product (see separate dataset record).The oceanic indicators that are provided are: 1) the temporal evolution of the global Mean Sea Level (MSL) DOI: ;2) the geographic distribution of Mean Sea Level changes (MSLTR) DOI: ;3) Maps of the amplitude and phase of the annual cycle (MSLAMPH) DOI: complete collection of v2.0 products from the Sea Level CCI project can be referenced using the following DOI: 10.5270/esa-sea_level_cci-1993_2015-v_2.0-201612.When using or referring to the SL_cci products, please mention the associated DOIs and also use the following citation where a detailed description of the SL_cci project and products can be found:Ablain, M., Cazenave, A., Larnicol, G., Balmaseda, M., Cipollini, P., FaugÃ¨re, Y., Fernandes, M.
