[Description] This dataset is curated for a manuscript submitted to Earth and Space Science by Hoyeon Shi and his colleagues in April 2024. It consists of three directories, each described below. A more detailed description of this dataset is available in the preprint (doi: 10.22541/essoar.171500700.06739421/v1 ). 01_retrieval_results This directory includes CryoSat-2-based monthly fields of Arctic sea ice thickness, snow depth, total freeboard, ice freeboards, ice draft, and bulk sea ice density for the winter months (January-March) of the 2011-2022 period. Those variables are obtained using six combinations of two retrieval methods and three radar freeboard correction methods. Retrieval methods alpha method: A simultaneous retrieval method based on Shi et al. (2020) and Shi et al. (2023), combining CryoSat-2, AVHRR, and AMSR data CS2IS2 method: A simultaneous retrieval method based on Kwok and Marcus (2018) and Kwok et al. (2020), combining CryoSat-2 and ICESat-2 data Radar freeboard correction methods Wave speed correction method: Mallet et al. (2020) Empirical correction method: An empirical correction derived from the CS2_OIB_matchup data, using snow depth as a predictor Bias correction method: An empirical correction derived from the CS2_OIB_matchup data, doing bias correction The datasets used for generating this dataset are as follows: CryoSat-2 - AWI CryoSat-2 sea ice thickness v2p4 (ftp://ftp.awi.de/sea_ice/product/cryosat2/v2p4/) ICESat-2 - NSIDC ATL20 dataset (doi: 10.5067/ATLAS/ATL20.004 ) AVHRR - Copernicus Marine Service's surface temperature datasets (doi: 10.48670/MOI-00130 , doi: 10.48670/MOI-00123 ) AMSR - JAXA AMSR-E 6.9 GHz brightness temperature (doi: 10.57746/EO.01gs73ayng11rpwk7n54aynyj1 ) - JAXA AMSR2 6.9 GHz brightness temperature (doi: 10.57746/EO.01gs73b1nzeh3g66jr4p04mr0j ) Auxiliary data - Sea ice concentration: OSI SAF (doi: 10.15770/EUM_SAF_OSI_0013 , doi: 10.15770/EUM_SAF_OSI_0014 ) - Sea ice type: OSI SAF (doi: 10.15770/EUM_SAF_OSI_NRT_2006 ) The naming convention is ...
