Estimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...
متن کاملComparison of Kuroshio Surface Velocities Derived from Satellite Altimeter and Drifting Buoy Data
Sea-surface geostrophic velocities for the Kuroshio region calculated from TOPEX/ POSEIDON altimetry data together with in situ oceanographic data are compared with surface velocities derived from drifting buoy trajectories. The geostrophic velocities agree well with the observed velocities, suggesting that the Kuroshio surface layer is essentially in geostrophic balance, within measurement err...
متن کاملStatistical downscaling of GRACE gravity satellite-derived groundwater level data
With the continued threat from climate change, population growth and followed by increasing water demand, the need for hydrological data with high spatial resolution and proper time coverage to be felt more than ago. Therefore, having data such as terrestrial water storage changes and groundwater level changes with high resolution spatial helps to plan and make decisions for water resource mana...
متن کاملComparisons of Cloud Heights Derived from Satellite and Atmospheric Radiation Measurement Surface Lidar Data
Cloud heights derived from single-channel, satellite infrared data can be relatively uncertain under certain conditions such as overlapped or optically thin clouds. During the daytime, optical depths derived from 0.63 μm visible (VIS) reflectances are used to adjust the altitude of optically thin clouds. Without the adjustment, the cloud heights are significantly underestimated diminishing the ...
متن کاملEvolution of the Satellite Radar Altimeter
The radar altimeters flown on Geos-3 (1975), Seasat-l (1978), and Geosat-l (1985) have amply demonstrated the benefits of high-precision measurements of ocean-surface topography, both to geodesy and to oceanography. Two new altimetry missions are planned: the joint NASA/Centre National d'Etudes Spatiales TOPEx/Poseidon mission, to be launched in 1992, and the Navy's Special Purpose Inexpensive ...
