Launched 10 June 2011, the NASA's Aquarius instrument onboard the Argentine built and managed Satélite de Aplicaciones Científicas (SAC-D) has been tirelessly observing the open oceans, confirming and adding new knowledge to the not so vast measured records of the Earth's global oceans. This paper reviews the data collected to date, findings, challenges and future work that is at hand for the sleepless...
Using five kinds of satellite-derived sea surface temperature (SST) from infrared radiometers (AVHRR, MODIS/Aqua, MODIS/Terra) and microwave radiometers (TMI, AMSR), a set of high-quality, cloud-free, high-resolution (1/20°) merged SST product was generated through an optimum interpolation scheme. The area of merged SST product (OISST) [0–42°N, 95–150°E] covers the whole China Sea as well as the western...
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER ) has operated since 19 December 1999 from NASA's Terra Earth-orbiting, sun synchronous satellite. Emissivity and temperature standard products are based on the TES algorithms and required periodical validation campaign. In the frame of the EC project PREVIEW (http://www.preview-risk.com/) a field campaign on Volcano Teide was...
The cosmic microwave background (CMB) is a cornerstone of modern cosmology; extracting cosmological information from it requires high accuracy instruments as well as a great deal of signal processing. This article highlights a critical step of the CMB data processing pipeline: the construction of a likelihood function for the statistical exploitation of CMB data. Since this task is based on a sky...
