  • External calibration in L-Band 2D synthetic aperture radiometers: application to sea surface salinity retrieval

    The SMOS(Soil Moisture and Ocean Salinity) Mission was selected in May 1999 by the European Space Agency to provide global and frequent soil moisture and sea surface salinity maps. SMOS' single payload is MIRAS(Microwave Imaging Radiometer by Aperture Synthesis), an L-band 2D aperture synthesis interferometric radiometer with multiangular observation capabilities. To achieve the ultimate goal of 0.1 psu error in ocean salinity retrievals, most studies assume the independence of measurements both in time and space so that the standard deviation of the retrieval errors decreases with the inverse of square root of the number of measurements being averaged. However, biases in the brightness temperature images originated from errors in the noise injection radiometers. Sun contributions to the antenna temperature, and imaging under aliasing conditions need to be compensated before attempting to retrieve the sea surface salinity. This work presents an external calibration suitable to perform salinity retrievals with an acceptable error. This study has been performed using the SMOS End-to-end Performance Simulator(SEPS) including thermal noise, all instrumental error sources, current error- correction and image reconstruction algorithms, and correction of atmospheric and sky noises. Simulation results show a retrieved salinity error of /spl sim/1 psu in one overpass over open ocean, which can be reduced afterwards by spatio-temporal averaging, much better than the -5 psu error that appears when image biases are not corrected.

  • Aquarius/SAC-D Ocean Salinity Mission Science Overview

    Scheduled for launch in 2009, the international Aquarius/SAC-D satellite will begin a mission to map the global sea surface salinity (SSS) field and its variability from space. The overarching scientific goal is to provide the essential data to study the interactions between the ocean circulation, global water cycle and climate. Key scientific issues to address are (1) mapping large expanses of the unexplored ocean, (2) understanding the seasonal and interannual SSS variations and the link to precipitation, evaporation and sea- ice patterns, (3) links between SSS and circulation variations in the North Atlantic overturning circulation, (4) air-sea coupling processes in the tropics that influence El Nintildeo, and (4) closing the marine freshwater budget. The satellite will provide repeat global coverage every 7 days with a footprint resolution ranging from 90 to 150 km over a three-beam ~390 km wide swath. Monthly SSS means will have an average root mean square (rms) accuracy of 0.2 psu at a spatial resolution of 150 km. Accuracies will be somewhat better in the tropics than high latitudes. Coincident microwave measurements of rain, sea ice and surface wind speed will be made with a resolution of about 45 km. The mission duration is initially three years, with probable extensions of two or more years.

  • The Aquarius Ocean Salinity Mission High Stability L-band Radiometer

    The NASA Earth Science System Pathfinder (ESSP) mission Aquarius, will measure global ocean surface salinity with ~120 km spatial resolution every 7-days with an average monthly salinity accuracy of 0.2 psu (parts per thousand) [1]. This requires an L-band low-noise radiometer with the long-term calibration stability of les0.15 K over 7 days. The instrument utilizes a push-broom configuration which makes it impractical to use a traditional warm load and cold plate in front of the feedhorns. Therefore, to achieve the necessary performance Aquarius utilizes a Dicke radiometer with noise injection to perform a warm - hot calibration. The radiometer sequence between antenna, Dicke load, and noise diode has been optimized to maximize antenna observations and therefore minimize NEDT. This is possible due the ability to thermally control the radiometer electronics and front-end components to 0.1degCrms over 7 days.

  • Thermal stabilized front-end PCB with active cold calibration load for L-band radiometer

    In this paper, the thermally stabilized front-end of an L-band total power receiver is presented. Applications on the L-band have become one of the most important focus points in the field of passive microwave remote sensing. Measuring environmental parameters such as ocean salinity and soil moisture remain a challenge, posing strict requirements to instrument performance. For traditional radiometers, especially the stability of front-end components is critical. The principle of the stabilization technique and the actual design are described. The design also features an on-board active cold load for calibration purposes. The presented technique aims to stabilize the front-end section PCB with heaters to sub 0.05 C level.

  • A nonlinear optimization algorithm for evaluating the performance of microwave imager combined active/passive

    The Microwave Imager Combined Active/Passive (MICAP) is a suit of active/passive instrument package, which has been proposed for demonstrating the capability of remote sensing the sea surface salinity (SSS), sea surface temperature (SST) and wind speed (WS). In this paper, a nonlinear optimization algorithm for simultaneous retrieval of the above parameters is described. The sensitivity of active/passive microwave observations to SSS is analyzed using the nonlinear optimization algorithm. The results show that the root mean square (RMS) error on the retrieved SSS estimated by using the nonlinear optimization algorithm is enough to meet the requirement of Ocean Salinity Satellite. This is submitted for the special session of “New Developments of Chinese Oceanographic and Meteorological Satellites”.

  • Sea Surface Salinity Retrieval Throughout a SMOS Half-Orbit Using Neural Networks

  • Extended Ocean Salinity Error Budget Analysis within the SMOS Mission

    The Soil Moisture and Ocean Salinity mission will provide from 2009 onwards sea surface salinity maps over the oceans. In this paper an ocean salinity error budget is described. Instrumental, external noise sources and geophysical errors have been analysed, stressing their relative degree of impact. With the aim of improving this study, an extended version of this analysis provides an overall vision of the salinity retrieval in a wider set of configurations.

  • On the reduction of the systematic error in imaging radiometry by aperture synthesis: a new approach for the SMOS space mission

    The SMOS mission is a European Space Agency project aimed at global monitoring of surface Soil Moisture and Ocean Salinity from radiometric L-band observations. This work is concerned with the reduction of the systematic error (or bias) in the reconstruction of radiometric brightness temperature maps from SMOS interferometric measurements. A recent and efficient method has been proposed for reducing this error. However, a residual bias still persists. A new approach for reducing this bias down to residual values less than 0.1 K is presented here and illustrated with numerical simulations.

  • Development of a high-stability microstrip-based L-band radiometer for ocean salinity measurements

    The development of a microstrip-based L-band Dicke radiometer with the long- term stability required for future ocean salinity measurements to an accuracy of 0.1 psu is presented. This measurement requires the L-band radiometers to have calibration stabilities of les 0.05 K over 2 days. This research has focused on determining the optimum radiometer requirements and configuration to achieve this objective. System configuration and component performance have been evaluated with radiometer test beds at both JPL and GSFC. The GSFC test bed uses a cryogenic chamber that allows long-term characterization at radiometric temperatures in the range of 70 - 120 K. The research has addressed several areas including component characterization as a function of temperature and DC bias, system linearity, optimum noise diode injection calibration, and precision temperature control of components. A breadboard radiometer, utilizing microstrip-based technologies, has been built to demonstrate this long-term stability

  • Acoustic tomography as a tool for the Arctic Ocean salinity monitoring: feasibility and perspectives

    It is shown that changes in the sound speed in the upper Arctic basin are due to changes in salinity, while temperature is nearly always close to freezing point. The possibility for the remote sensing of the upper ocean salinity by acoustic tomography (acoustic halinometry) is demonstrated by oceanographic and acoustic numerical modeling using data obtained in the Arctic basin during winter oceanographic surveys in 1973-79.
