Sea level variations are obtained using periodogram analysis of the SNR signal and compared to synthetic gauge generated from two independent tide gauges. The choke ring antenna provides poor result, with an RMS around 6 cm and a correlation coefficients of 0.89. The smaller antennas provide ...
Measurement of ocean wave heights with the synthetic aperture radar can be accomplished with high spatial resolution by determining the variation of speckle intensity with the frequency and angle of illumination. A comparison of data obtained by the SEASAT SAR with surface truth measurements obtained du...
2.2.3. Measurement of 2D and 3D metrics For each colony 3D model, the planar area (i.e. 2D projected area) was calculated with the geographic information system (GIS) software Global Mapper (version 19.0), using spatial analysis tools from an orthographic projection of the 3D models (Fig....
This dissertation presents new research into the study of simulation and measurement techniques for microwave remote sensing of sea ice. We have embarked o... DK Isleifson 被引量: 0发表: 2010年 Sea surface temperature estimation using active/passive microwave remote sensing Although the sea surface...
Very low frequency (VLF) sea level variations are an important indicator of global climate change, and their measurement can provide important information for determining the socioeconomic impact of sea level change on coastal land use. The prospect of measuring VLF sea level variations has been ...
SLIPs, both scenarios adopt a uniform indicative depth distribution based on original publications. The MC sampling process also accounts for the error propagation associated with any GIA correction applied and elevation measurement uncertainties (see Methods). We calculate chronological probability ...
Evapotranspiration measurement and estimation using modified Priestley–Taylor model in an irrigated maize field with mulching. Agric. For. Meteorol. 168, 140-148 [17] El Mouatassime, S., Boukdir, A., Karaoui, I., Skataric, G., Nacka, M., Darvishan, A.K., Spalevic, V., 2019....
The Baltic Sea has been measured using airborne gravimetry with the accuracy of about 2 mGal. Therefore, the gravimetric geoid is not fully reliable for the region either. If we take into account the tilt of the water level at the moment of measurement, we can observe the relative change ...
This talk compares the ambient noise observed during SPICEX and PhilSea with results reported in the literature. Since these data sets contain receptions over the period of a year, we focus on the seasonal dependence of the noise field. In addition to investigating noise level as a function ...
