ISAS-SSS: In situ Sea Surface Salinity gridded fields

A new version of the ISAS product is available at : https://doi.org/10.17882/52367 The In Situ Analysis System (ISAS) was developed to produce gridded fields of temperature and salinity that preserve as much as possible the time and space sampling capabilities of the Argo network of profiling floats. The ISAS-SSS configuration provide Sea Surface Salinity gridded fields from in-situ measurements including Argo, Moorings, Marine Mammals, GOSUD Thermosalinometer SSS measurements from delayed mode SNO-SSS merchant ships (http://www.legos.obs-mip.fr/observations/sss), French research vessels (http://doi.org/10.17882/39475) and sails (http://doi.org/10.17882/39476). A careful delayed mode processing of the 2002-2015 dataset has been carried out using version 7 of ISAS and updating the statistics to produce the ISAS-15 analysis. The ISAS-SSS fields appears as highly valuable for the "calibration and validation" of the new satellite observations delivered by SMOS, Aquarius and SMAP.

背景概述

ISAS-SSS数据集是基于原位测量（如Argo浮标、系泊设备和海洋哺乳动物）生成的海表盐度网格化场，覆盖2002-2015年，采用ISAS-15分析方法进行延迟模式处理。该数据集主要用于卫星观测（如SMOS、Aquarius和SMAP）的校准和验证，具有高时空采样能力。
