2013 International Geoscience and Remote Sensing Symposium
The theme of this year's Geoscience and Remote Sensing Symposium (IGARSS) was "Building a Sustainable Earth Through Remote Sensing". Aquarius-related papers covered applications such as inter-comparison with SMOS, sea surface salinity wind and roughness corrections, seawater permittivity model functions, radio frequency interference, and mapping of the DOME-C area (Antarctica). IGARSS is sponsored by the Institute of Electrical and Electronics Engineers (IEEE).
Aquarius RFI Detection and MitigationLe Vine, D.M., de Matthaeis, P., Ruf, C., Chen, D., and Dinnat, E.P. (17-Sep-15). Monitoring salinity from space is a particularly sensitive measurement and RFI is a concern, even in the protected band at 1.4 GHz where the Aquarius radiometers operate. To protect against RFI, the Aquarius radiometer samples rapidly and a glitch detection algorithm is employed to check each sample for RFI.
Aquarius Salinity and Wind Retrieval Using the CAP Algorithm and Application to Water Cycle Observation in the Indian Ocean and SubcontinentYueh, S., Wenqing, T., Fore, A., Hayashi, J.C.A., Lagerloef, G., Jackson, T., and Bindlish, R. (17-Sep-15). The primary science objective of the Aquarius mission is to monitor the seasonal and interannual variation of the large scale features of the surface salinity field in the open ocean.
Evaluation of Sea Surface Salinity Observed by Aquarius and SMOSEbuchi, N. and Abe, H. (17-Sep-15). Sea surface salinity data derived from Aquarius and Soil Moisture and Ocean Salinity missions are being compared with observations by Argo floats in the global oceans and outputs from a global ocean data assimilation system.
Inter-Comparison of SMOS and Aquarius Brightness Temperatures at L-band Over Selected TargetsPablos, M., Piles, M., Gonzalez-Gambau, V., Vall-Ilossera, M., and Camps, A. (15-Sep-15). The spectral window at L-band is a reserved wavelength that is used for the SMOS and Aquarius/SAC-D missions. Thus, these two missions are being compared to verify the continuity and consistency of the data.
L-band Characterization of Dome-C Region Using Ground and Satellites DataMacelloni, G., Brogioni, M., Pettinato, S., Montomoli, F., Monti, F., and Casal, T. (17-Sep-15). East Antarctic Plateau has been investigated in recent years as a potential candidate for higher reference temperatures. The reason for this interest lies in its geographical location, as well as in the size, structure, spatial homogeneity, and thermal stability of this area.
Sea Surface Roughness Correction at L-band for Aquarius InstrumentJones, W.L., Hejazin, Y., and El-Minri, S. (17-Sep-15). This paper provides an alternative approach using a theoretical Radiative Transfer Model (RTM) driven by numerical weather forecast model for ocean surface wind vector.
Seawater Permittivity Model Function With New L-band Seawater Measurements at 33psuZhou, Y., Lang, R.H., Utku, C., and Le Vine, D. (17-Sep-15). In this paper, a new seawater dielectric model function is introduced including the latest permittivity data for seawater with salinity 33 psu. Finally, the validation of the end-effect, measurement variance and data fitting will be discussed.
