This was done in order to assess the distribution effect of the urban heat island (UHI) in a non traditionally way (thermal fluxes and related properties instead of surface and air temperatures information). In this study, a spectral-based approach was used to process data from the DAIS sensor to yield diverse thermal parameters over Afula city, Israel. The DAIS sensor consists of 79 bands across the VIS-NIR-SWIR-TIR spectral region. Seven bands across the TIR region permit the extraction of parameters such as emissivity and energy fluxes on a pixel-by-pixel basis using the information from the VIS-NIR-SWIR region. Following R. Richter's (1996) steps we used the DAIS data in conjunction with ground data taken at the time of the overpass to obtain spatial thermal recognition of the selected city. Comparing the results to the traditional UHI map (air and surface temperature) shows that the spectral-based maps provide additional information about the UHI that cannot be extracted in the traditional way.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

Because of the continuous global measurements of SST that satellites can provide they play a fundamental role in acquiring the data sets necessary for studies of such global processes. However, the satellite data still need to be validated against in-situ measurements in order to assess the accuracy of satellite SST retrieval algorithms. Since 1997 radiometric sea surface skin temperatures have been recorded monthly using a TASCO radiometer along a cross shelf transect extending 40 km offshore from a coastal location north of Perth, Western Australia. This SST measurement program is one component of the Hillarys Transect, an ongoing multidisciplinary oceanographic study which aims to quantify the seasonal variation of physical and biological variables in the coastal Indian Ocean. Validation of satellite SST retrieval algorithms is the primary aim of the SST measurement program component of the Hillarys Transect, which also aims to develop a data set which captures the seasonal variation of SST off the coast of southern Western Australia (WA). The radiometric SST measurements are made at 9 stations along the transect and each measurement is calibrated using a portable water-filled blackbody unit. Though the study is low budget, the seasonal variation in SST is clearly captured by the data set and good agreement between in-situ and satellite SST estimates are obtained. Calibration of the radiometer is discussed along with the seasonal cycle of SST off the WA coast and the suitability of the instrumentation for validation of remotely sensed SST.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

In the course of this project the first space born single pass interferometer has mapped the Earth's topography. Two different radar systems operated on board of the space shuttle: the C-band radar of the American NASA/JPL and the X-band radar of the German DLR and the Italian ASI. It is the objective of this mission to generate a digital elevation model (DEM) of the Earth with an accuracy that has never been reached before on this global scale. The inevitable technically caused oscillation of the secondary antenna turns this task into a scientific and technological challenge. The Synthetic Aperture Radar (SAR) observation is influenced by a resulting sensor motion in the line of sight. The consequence of this effect on the secondary SAR scene and subsequently on the DEM is described in this paper. To obtain the requested height accuracy in spite of the antenna oscillation, the principle of motion compensation is applied. The concept of this key algorithm in the X-SAR SRTM project is explained in detail. The essential parameters of the interferometric observation geometry were recorded by the Attitude and Orbit Determination Avionics (AODA) system of the JPL. These AODA data are employed to investigate the movement of the secondary antenna.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings.

For a single aperture SAR, the coherent processing interval (CPI) and bandwidth determine the number of independent measurements collected; therefore, the received time-bandwidth product limits the maximum unambiguous illumination area, or swathwidth. For a multiple aperture SAR (MSAR), however, the rank of the received signal is not as easy to determine. When the array is large, its beamwidth determines resolution rather than the radar's bandwidth and CPI length. Furthermore, redundant lags in the space-time-frequency co-array reduce the amount of unique information collected. This paper generalizes the theory behind determining the rank of a signal received from stationary targets. Resolution is determined by all radar parameters including CPI length, bandwidth, and array extent. The co-array concept for antenna arrays, which is a measure of the lags sampled in the array's spatial covariance matrix, is extended and applied. A hybrid coarray is derived that indicates lags sampled in the hybrid spacetime-frequency space. The hybrid co-array is then applied to signals received by MSAR to show that the number of unique lags in the hybrid co-array limits the number of unique samples collected. The results provide important analysis tools for MSAR systems that are likely in the future, especially sparse, constellation-flying satellite systems.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

Structural crust is a thin compact layer generated on the soil surface after rainstorm events due to raindrop energy. The crust significantly affects several soil physical properties, such as infiltration, runoff and soil erosion. In this study, a controlled spectral investigation of the properties of structural crust, using infiltration rate as an indicator, was carried out. A set of soil samples was subjected to increased levels of cumulative energy from a simulated rainstorm while measuring the infiltration rate. After drying the soil samples, their spectral features across the SWIR region (1.2 /spl mu/m-2.4 /spl mu/m) were studied in the laboratory. Empirical relationships were found between the infiltration rate and reflectance values (either in raw or in first derivative domains). Although further study is required to fully account for other soils, rainstorm energies and water qualities, this technique suggests great potential as a tool for rapid, nondestructive, in situ assessment of crusted soil properties in soils.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.
