Evaluation of sea surface salinity observed by Aquarius [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Sea surface salinity data derived from Aquarius on the SAC-D satellite were compared with observations by Argo floats in the global oceans to evaluate the quality of the Aquarius salinity measurement and assess the error structure in the data. In tropical and mid latitudes, salinity observed by Aquarius agreed well the Argo data with an rms difference ...

Sea Surface Salinity Short Term Variability in the Tropics [PDF]

Ocean Science, 2021
Abstract. Using data from the Global Tropical Moored Buoy Array we study the validation process for satellite measurement of sea surface salinity (SSS). We compute short-term variability (STV) of SSS, variability on time scales of 5–14 days. It is meant to be a proxy for subfootprint variability as seen by a satellite measuring SSS.

Assessment and Improvement of Sea Surface Microwave Emission Models for Salinity Retrieval in the East China Sea

Remote Sensing, 2019
Accurate prediction of sea surface emission is the key for sea surface salinity retrieval from satellite microwave radiometer. In order to retrieve salinity from satellite observation, several sea surface microwave emission models have been developed ...

Variability of Satellite Sea Surface Salinity Under Rainfall [PDF]

, 2020
Two L-Band (1.4 GHz) microwave radiometer missions, the Soil Moisture and Ocean Salinity (SMOS) and the Soil Moisture Active and Passive (SMAP) missions, currently provide salinity measurements in the first centimeter below the sea surface. At this depth, salinity variability at hourly temporal scales is dominated by the impact of precipitation.

Simulations of sea surface reflection for V-band O2 differential absorption radar barometry

Frontiers in Remote Sensing, 2023
This study simulates V-band sea surface reflectance and normalized radar cross-section (NRCS) for sea surface air pressure barometry using a differential absorption radar operating at three spectrally even spaced close frequency bands (65.5, 67.75 and 70.

Sea surface emissivity observations at L-band: first results of the Wind and Salinity Experiment WISE 2000 [PDF]

, 2002
Sea surface salinity can be measured by passive microwave remote sensing at L-band. In May 1999, the European Space Agency (ESA) selected the Soil Moisture and Ocean Salinity (SMOS) Earth Explorer Opportunity Mission to provide global coverage of soil ...

Nine years of SMOS sea surface salinity global maps at the Barcelona Expert Center

Earth System Science Data, 2020
. After more than 10 years in orbit, the Soil Moisture and Ocean Salinity (SMOS) European mission is still a unique, high-quality instrument for providing soil moisture over land and sea surface salinity (SSS) over the oceans.
