Analysis of Envisat Ra-2 Backscatter over Natural Land Calibration Targets
نویسندگان
چکیده
Natural land targets for ERS RA-1 backscatter, including the Simpson desert, the Takla Makan, parts of the Sahara and the Arabian desert, have previously been identified and modelled using ERS-1 Geodetic Mission and Tandem Mission data. These have been used to perform cross-calibration of ERS-1/2 ice and ocean mode altimeter σ0. The advent of the Envisat RA-2 provides an opportunity to study the behaviour of RA-2 backscatter over land, both at Ku and S bands. This paper presents an analysis of RA-2 backscatter performance over natural land targets, and provides a detailed comparison with ERS RA-1 data.

Land Calibration and Monitoring of Envisat Ra-2 Sigma0
ASTRACT A global evaluation of RA sigma0 has been carried out over all non-ice covered land surfaces for which altimeter data are available, using ERS-1 Geodetic Mission data, together with ERS-1 and ERS-2 35 day data. This global survey has identified several large land areas over which the surface characteristics and aridity permit cross-calibration of altimeter sigma0 to be made to an accura...
متن کاملEnvisat Ra-2: Potential for Land Topographic Mapping
The ERS-1 and ERS-2 missions have generated a huge database of returns from the earth's land surfaces. The inclusion of an ice mode has allowed, for the first time, detailed height information to be obtained over much of the complex topography overflown by these missions. However, the inability of the altimeter to maintain lock over extreme terrain has constrained to some extent the scope of la...
متن کاملInter-calibration of Ers Ami and Metop Ascat Backscatter Measurements
Scatterometer derived products have become an important input dataset for climate change research. For this reason accurate radiometric calibration of scatterometer is a prime requirement from the scientific community to enable them to establish a long-term consistent scatterometer dataset. The calibration method that we introduce here is a stepwise relative calibration approach using extended ...
متن کاملA Global Assessment of the Ra-2 Performance over All Surfaces
The EnviSat RA-2 has collected a huge volume of echoes from the earth's surface. Its unique modeswitching capability has enabled it to remain in lock even over mountainous terrain, and has resulted in the most complete sampling of the earth's surface by a satellite radar altimeter. This paper presents results from the global analysis of the RA-2 echoes over all surfaces, including a comparison ...
متن کاملRa-2/mwr Cross-calibration and Validation: Objectives, Approach, Results and Recommendations
ENVISAT carries a new generation radar altimeter (RA-2) and a microwave radiometer (MWR). RA-2 provides improved measurement performances and many new capabilities, which will benefit the science and application community. With almost two decades of altimetric measurements acquired by ESA, long-term evolution of parameters playing a key role in climate change can be addressed. This requires hom...
