“…8, it can be clearly seen that abruptly decreases for wind speed lower than 3 m s . This behavior was observed at 2.65 GHz by [25] during a flight above Chesapeake Bay. It was not observed during the EuroSTARRS flight, probably because both the and the wind speed measurements were noisy; it is known that the scatterometer measurements are very inaccurate below 3 m s .…”

Abstract-The results from two field experiments in the Mediterranean Sea are used to study the wind speed dependence of brightness temperature at L-band. During the EuroSTARRS airborne experiment, an L-band radiometer made measurements across a large wind speed gradient, enabling us to study this dependence at high wind speed. We compare our results with a two-scale emissivity model using several representations of the sea state spectrum. While the results are encouraging, unfortunately the accuracy of the measurements does not permit us to distinguish between the so-called twice Durden and Vesecky spectrum and the Elfouhaily spectrum above 7 m s 1 . The effect of foam is certainly small. During the WISE 2001 field experiment carried on an oil rig, we studied this dependence at low wind speed, finding an abrupt decrease of the wind speed effect on the brightness temperature below 3 m s 1 .

“…(19,26,27) Radiation at microwave frequencies between 1.5 and 5.0 GHz is only slightly attenuated by atmospheric gases. (28) It has been observed that the frequency range of 0.5 to 4.0 GHz is best suited for salinity estimation. (29) The presence and concentration of various chloride solutions are also clearly evident in the changes in the amplitude and resonance frequency of the signal occurring especially at frequencies below 4.0 GHz.…”

We present a near-field microwave sensor based on a hairpin resonator for detecting aqueous ethanol and aqueous NaCl concentrations in microfluidics. A hairpin sensor with a high-quality (high-Q) dielectric resonator allows the detection of a small variation in the aqueous NaCl concentration by measuring the scattering parameter (S 21) responses at resonance frequencies. The responses caused by the test liquids with various dielectric constants in aqueous ethanol solution were observed at operating frequencies of 1.9 and 2.1 GHz. The detection of various concentrations of NaCl in solution was also achieved. The changes in S 21 at resonance frequencies are directly related to changes in the aqueous NaCl concentration because of the electromagnetic interaction between the resonator and the NaCl solution. The stable linear relationships are advantageous for detecting and analyzing aqueous ethanol and aqueous NaCl concentrations. It shows that the sensor is reliable for both dielectric constant and conductivity detection in liquid. The hairpin resonator, which is easily fabricated by standard printed circuit board (PCB) technology, has great potential for microfluidic sensing applications.
