Successfully launched on 30 May 2016, ZY3-02 is the first Chinese surveying and mapping satellite equipped with a lightweight laser altimeter. Calibration is necessary before the laser altimeter becomes operational. Laser footprint location prediction is the first step in calibration that is based on ground infrared detectors, and it is difficult because the sample frequency of the ZY3-02 laser...

A model for ocean wave period from satellite altimeter data proposed by Gommenginger et al (2003; [1]) was applied to a dataset of ENVISAT RA2 measurements collocated with moored buoy data for cycle 15 to 26. Although the ocean wave period model was developed for Topex data gathered between 1993 and 1998, we find that the model performs equally well for RA2 Kuband without any need for adjustmen...

We form a new 'blended' data set of sea level anomaly (SLA) fields by combining gridded daily fields derived from altimeter data with coastal tide gauge data. Within approximately 55-70 km of the coast, the altimeter data are discarded and replaced by a linear interpolation between the tide gauge and remaining offshore altimeter data. To create a common reference height for altimeter and tide g...

Quasi-simultaneous measurements of the ocean surface by the Canada Centre for Remote Sensing (CCRS) Convair-580 (CV-580) synthetic aperture radar (SAR) were acquired on March 20, 1988, along an ascending pass of the Geosat radar altimeter as part of the prelaunch ERS-1 Norwegian Continental Shelf Experiment (NORCSEX '88). Over a region where the SAR look direction is parallel to the wind vector...

Surface topography is of great importance in radar back scattering, but the quantitative interpretation of data collected in the field is still a difficult problem. We present topographic profiles at 25-cm and 5-cm horizontal resolution for three sites along a lava flow on KUauea Volcano, and use these data to illustrate techniques for surface roughness analysis. Height and slope distributions ...

A crossover method for determining zonal and meridional ocean current components is examined using data at three crossovers of TOPEX/Poseidon and JASON-1 ground tracks over 2002 2006. To implement this method, a geoid model around Taiwan is constructed using surface and airborne gravity data. The modeled and observed geoidal heights at coastal benchmarks are consistent to 5 cm RMS with the mean...

Nadir-looking microwave radiometers are flown on different altimeter missions to correct the altimeter range for water vapor and cloud liquid water path delay in the troposphere. Actually four sensors, TOPEX, JASON-1, ERS2, and ENVISAT micro-wave radiometers (MWR) provide continuous measurements and the aim of this paper is to compare their measured brightness temperatures over the same hot ref...

The quantitative measurement of surface roughness of planetary surfaces at all scales provides insights into geological processes. Complementary of the analysis of local topographic data of the Martian surface at kilometer scale, as achieved from the Mars Orbiter Laser Altimeter (MOLA) data, and at the sub-centimeter scale using photometric properties derived from multi-angular observations, a ...
