The Aquarius/SAC-D joint international science mission, a collaborative effort between NASA and the Argentine Space Agency, CONAE, was launched on June 10, 2011. The purpose of the Aquarius/SAC-D mission is to provide measurements of global sea surface salinity (SSS), which will be used to understand climatic changes of the global water cycle and how these(More)
The Microwave Radiometer (MWR) on the Aquarius/SAC-D mission measures microwave radiation from earth and intervening atmosphere in terms of brightness temperature (T<sub>b</sub>). It takes measurements in a push-broom fashion at K- (23.8 GHz) and Ka-band (36.5 GHz) frequencies using two separate reflector antenna systems, each producing eight spot beams.(More)
This paper concerns the Microwave Radiometer (MWR) instrument on the Aquarius/SAC-D satellite, and it discusses the development of a signal processing algorithm to infer rain rate over oceans using the measured MWR microwave brightness temperatures. On-orbit rain measurements are presented and compared with corresponding independent &#x201C;surface(More)
Uncovering the genetic and developmental changes that generate morphological diversity is one of the longstanding challenges in biology. The developmental process generating the spine, one of the defining features of vertebrates, constitutes one of these core questions. The vertebral column is patterned in early development through the formation of(More)
A linguistic ellipsis, most generally expressed, is a truncated or partial linguistic form. It is a linguistic form in which constituents normally occurring in a sentence are superficially absent, licenced by structurally present prior antecedents. INTRODUCTION A linguistic ellipsis, most generally expressed, is a truncated or partial linguistic form. This(More)
