    | No Comments. Satellite Altimetry Over Oceans and Land Surfaces (Earth. The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the.

Despite having over regular users and providing a key data base for monitoring ocean circulation, sea-level rise, and other ocean variability, this Ocean Altimeter Pathfinder Project was discontinued in Herein we propose building on our previous work with the Ocean Altimeter Pathfinder Project—by availing ourselves of the recent.

The Ocean Altimeter Pathfinder Project involves the reprocessing of all altimeter observations with a consistent set of improved algorithms, based on the results from TOPEX/POSEIDON (T/P), into easy-to-use data sets for the oceanographic community for climate research.

The paper is devoted to the application of satellite altimetry from the TOPEX/Poseidon and ERS-1 missions to the Black Sea. We use the NASA Ocean Altimeter Pathfinder Project collinear data set and monthly climatic hydrography to restore the dynamical sea level, that which connected with the Black Sea circulation.

The Ocean Altimeter Pathfinder Project involves the reprocessing of all altimeter observations with a consistent set of improved algorithms, based on the results from TOPEX/POSEIDON (T/P), into easy-to-use data sets for the oceanographic community for climate research.

The project currently utilizes near-real time data from the Jason-3 mission, and archive data from the Jason-2/OSTM, Jason-1, Topex/Poseidon, and ENVISAT missions.

Data processing procedures closely follow methods developed by the NASA Ocean Altimeter Pathfinder Project (see references). NASA's OceanColor Web is supported by the Ocean Biology Processing Group (OBPG) at NASA's Goddard Space Flight Center.

Our responsibilities include the collection, processing, calibration, validation, archive and distribution of ocean-related products from a large number of operational, satellite-based remote-sensing missions providing ocean color, sea surface temperature and sea surface.

A mean sea surface, GSFC00, and its derivatives, the altimetry gravity anomaly and vertical gravity gradient fields, were computed using sea surface heights of TOPEX, ERS, and Geosat satellite altimeter missions provided by the NASA Ocean Altimeter Pathfinder Project [Koblinsky et al., ].A new estimation method, distinct from the GSFC98 mean sea surface computation [Wang.

Because 1-per-s altimeter data records do not necessarily occur at precisely the same positions for each cycle, the 1-s altimeter heights were spatially interpolated onto a. As part of a new USDA-funded program, near-real time altimetric monitoring of the largest lakes and reservoirs in Africa will begin in October, Data ingestion and manipulation will closely follow the path of the NASA Ocean Altimeter Pathfinder Project and will concentrate in the first phase on incoming data from the Jason-1 mission.

In this study, we have used the sea level anomaly from the T/P satellite altimetry data of the NASA Ocean Altimeter Pathfinder Project, which is produced at the Goddard Space Flight Center (GSFC) (Koblinsky et al., ) and altimeter products of the CLS Space Oceanography Division as part of the Environment and Climate EU ENACT (project EVK2.

GEOS-3 (April - July ) – Geodynamics and Earth Ocean Satellite 3 (GEOS-3) was part of a geodetic mission series lead by NASA.

It launched on 9 April and continued operating until July The spacecraft carried a radar altimeter for mapping of the oceans, as well as a laser retroflector, and other tracking beacons.

The general objective of this project is to implement and validate innovative methodologies for the assimilation of the Jason-1 altimeter data into ocean and ecosystem models in order to contribute to the development of operational oceanography for programs such as MERCATOR and GODAE and related components (CLIVAR, GOOS, GCOS, etc.).

Most data processing procedures will closely follow methods developed by the NASA Ocean Altimeter Pathfinder Project, but an intermediate data set with approximately 4-days delivery time and cm height accuracy will be utilized.

NASA will semi-automate the data processing and deliver updated reservoir elevation graphs every 10 days. As is currently done for Geosat, the NASA Ocean Altimeter Pathfinder group will provide algorithm support for the GDR generation as well as producing higher level data sets.

Similarly, the NASA Ice Sheet Altimetry Pathfinder group will evaluate the GFO over-ice altimeter waveforms and provide measurements of ice sheet topography to the polar. Baroclinic tides can be observed both remotely from the Ocean Topography Experiment (TOPEX)/Poseidon (T/P) altimeter and in situ using current meters.

However, it is rare that current meter moorings have high vertical resolution and are located under T/P ground tracks so that a direct comparison can be made between the two methods of observations.

The RMS retrieval accuracy reported by Wentz for water vapor is mm, with the systematic errors in the retrieval being smaller than the RMS. The NOAA/NASA DMSP SSM/I Pathfinder project's final recommendation (Colton, ) for water vapor retrieval was the Wentz algorithm.

The TMR retrieval algorithm uses the, and GHz channels. In the report we have used the sea level anomaly from the T/P satellite altimetry data of NASA Ocean Altimeter Pathfinder Project, which are produced in Goddard Space Flight Center (GSFC) (Koblinsky.

et al., ). The anomalies are calculated relative to the GSFC model of the mean sea surface and include all standard geophysical corrections.

Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Launched on Januthe mission will extend the time series of ocean surface topography measurements (the hills and valleys of the ocean surface) begun by the TOPEX/Poseidon satellite mission in and continuing through the Jason-1 (launched in ) and the.

These RSSHs come from the NASA Ocean Altimeter Pathfinder Project [Koblinski et al., ]. Interpolated ECMWF surface winds at the measurement location are also provided in the distributed Jason‐1 products and this wind product will also be considered as SSB model parameter to test.

Ocean Surface Wind Vectors of 25Km/Km resolution. The QuikSCAT products of ocean surface winds at 10m height, as processed by NOAA/NESDIS, are retrieved using observation data from NASA/JPL's SeaWinds Scatterometer aboard the QuikSCAT.

The empirical retrieval model currently used is referred to as QSCAT1, which relates normalized radar cross-section with wind.

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other "ocean worlds" in our solar system and beyond.

The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescop.

The Surface Water Ocean Topography (SWOT) mission is a proposed NASA mission to make the first global survey of Earth's surface water. SWOT is being developed by an international group of hydrologists and oceanographers to provide a better understanding of the world’s oceans and its terrestrial surface waters.

Images from Mars Pathfinder. Mars Pathfinder impacted the surface on July 4 at UT ( PM EDT) at a velocity of about 18 m/s (40 mph) - approximately m/s vertical and m/s horizontal - and bounced about 15 meters (50 feet) into the air, bouncing another 15 times and rolling before coming to rest approximately minutes after impact and about 1 km from the initial impact site."Sea level is a measure of the heat stored in the ocean.

In the last month or so, the tropical Pacific has been switching from warm to cold. Lower sea level indicates less heat, hence a colder ocean," said Dr.
