ESA Sea Ice Climate Change Initiative (Sea_Ice_cci): Southern hemisphere sea ice thickness from Envisat on the satellite swath (L2P), v2.0

This dataset provides a Climate Data Record of Sea Ice Thickness for the southern hemisphere polar region, derived from the RA-2 (Radar Altimeter -2) instrument on the Envisat satellite. 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 daily sea ice thickness data on the satellite measurement grid (Level 2P) at the full sensor resolution for the period October 2002 to March 2012. Note, the southern hemisphere sea ice thickness dataset is an experimental climate data record, as the algorithm does not properly considers the impact of the complex snow morphology in the freeboard retrieval. Sea ice thickness is provided for all months but needs to be considered biased high in areas with high snow depth and during the southern summer months. Please consult the Product User Guide (PUG) for more information.

本数据集提供了南半球极地海区的海冰厚度气候数据记录，其数据源自恩维萨特（Envisat）卫星搭载的RA-2（雷达高度计-2，Radar Altimeter -2）仪器。该产品由海冰气候变化倡议（Sea Ice CCI）项目在欧洲空间局气候变化倡议计划（ESA Climate Change Initiative Programme，简称ESA CCI）框架下生成。数据集为2002年10月至2012年3月期间，位于卫星测量网格（Level 2P）、采用传感器全分辨率的逐日海冰厚度数据。需注意，本南半球海冰厚度数据集属于试验性气候数据记录，原因在于其干舷反演算法未充分考虑复杂积雪形态的影响。数据集覆盖全月份的海冰厚度数据，但在积雪较厚区域以及南半球夏季时段，数据存在系统性偏高偏差。如需了解更多详细信息，请参阅《产品用户指南》（Product User Guide，简称PUG）。
