    Satellites measure radiance, and inspection of data from the Multi-angle Imaging SpectroRadiometer (MISR) reveals that cloud cover does have an effect on the measured radiances over bright surfaces. MISR observations by employing a radiative transfer model to examine the effects of cloud micro- and macrophysical properties, surface albedo, sun and view angle on the top-of-atmosphere (TOA) measured...

  • The accuracy of SAGE III: comparing limb scattering measurements

    Publication Year: 2004, Page(s):4363 - 4366 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (454 KB) | HTML iconHTML

    Our intent is to compare the SAGE III limb scattering (LS) data to other instruments measuring similar ozone profiles. Comparisons made show an agreement in the mean ozone profile between SAGE III and OSIRIS LS measurements. Similar comparisons show an agreement between SAGE III and SOLSE/LORE data. Both comparisons show an accuracy and precision of relatively ten percent. The quality and accuracy... View full abstract»

    Land surface albedo, which is a fundamental component needed for determining the radiation balance of the Earth-atmosphere system, is the surface hemispherical reflectivity integrated over the solar spectrum. Briefly said, it is the ratio of the total upwelling irradiance to the total downward irradiance. Given the limit of experiment field and instrument equipment, it is very difficult to obtain ...

  • Aerosol Optical Thickness determination by exploiting the synergy of TERRA and AQUA MODIS (SYNTAM)

    Publication Year: 2004, Page(s):4371 - 4374 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (446 KB) | HTML iconHTML

    Aerosol retrieval over land remains a difficult task because the solar light reflected by the Earth-Atmospheric system mainly comes from the ground surface. Dark Dense Vegetation (DDV) for MODIS data has showed excellent competence at the aerosol distribution and properties retrieval, which is, however, restrictedly used for lower reflectance ground surface such as water body and dense vegetation....

    Publication Year: 2004, Page(s):4375 - 4378 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (424 KB) | HTML iconHTML

    Vegetation Index (VI) and Leaf Area Index (LAI) are very important parameters for crop growth situation monitoring and crop yield estimation. However, it is not easy to get accurate VI or LAI. One of the reasons is because of the difficulty in the inversion of aerosol optical depth (AOD), which is the key factor in atmospheric correction. This study addresses an algorithm of AOD inversion in Agric... View full abstract»

  • Monitoring of sea ice in Far East Russia

    Publication Year: 2004, Page(s):4379 - 4381 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1287 KB) | HTML iconHTML

    In Far East Russia, the Sea of Okhotsk is covered by sea ice in winter every year. The Amur River plays an important role of generating sea ice. Sea ice goes south by the monsoon. In this paper, we present a four-dimensional histogram method and a threshold method for detecting the sea ice pixels of NOAA AVHRR images. We used 699 scenes from February to March for five years from 1995 to 1999. We c... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (509 KB) | HTML iconHTML

    The algorithm for separating Baltic Sea Ice and open water from our operational SAR data are presented. The algorithm is based on segment wise autocorrelation with some simple additional rules to improve the classification. The algorithm results are compared to the open water and sea ice separation available in daily digitized ice charts and the algorithm performance is also compared to open water...

  • Study on the sea ice thickness observation in the Sea of Okhotsk by using dual-frequency and fully polarimetric airborne SAR (Pi-SAR) data

    Publication Year: 2004, Page(s):4386 - 4389 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (481 KB) | HTML iconHTML

    The Sea of Okhotsk is located in the most southerly region of the Northern Hemisphere in which sea ice exists during winter. Since the area and volume of the sea ice in this region are related to climate change locally as well as globally, it is important to develop methods for monitoring sea ice parameters around this region. Since Synthetic Aperture Radar (SAR) can observe continuously in any we... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (326 KB) | HTML iconHTML

    A linear regression model is developed to predict spring ice conditions in Hudson Bay 3 months in advance. The model has 8 atmospheric, oceanic and sea ice predictors that together explain 90% of the variability in the predicted time series with a MAE of 0.26. The categorical forecast accuracy ranges from 73% to 77% A series of diagnostics including Monte Carlo simulations are used to ensure that ... View full abstract»

  • An indexing method for spatial object in video using image processing and photogrammetry

    Publication Year: 2004, Page(s):4394 - 4397 vol.7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (428 KB) | HTML iconHTML

    To support video-map cross-reference and bi-directional search, it is necessary to index spatial object with regard to each video frame. However, it costs a great deal of effort to index spatial objects in all frames of video whose frame rate is about 30 frames/second. Therefore, we index spatial object only about 1 random frame per second, and index the spatial object in other frames by interpola... View full abstract»

    OLAP can answer questions such as 'what next' and 'what if'. OLAP, which always needs the support of data warehouse, is a complement to data mining. In the early steps of data mining progress, OLAP tools might be helpful in tasks such as exploring the data sets, locating more important variables and unwanted data, which can help users to understand the source data and quicken the data mining progr...

    The cumulative attenuation (A) along TRMM PR path given by the surface reference technique (SRT) can be distributed along the radar range using a power law relation between the specific attenuation (k) and reflectivity factor (z) written as, k=aZbeta. A commonly used approximation is that beta is constant and alpha changes according to the raindrop size distribution (DSD). More recently... View full abstract»

  • Semantics-based satellite image retrieval using low-level features

    Publication Year: 2004, Page(s):4406 - 4409 vol.7
    Cited by:  Papers (9)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (332 KB) | HTML iconHTML

    Content-based techniques enable retrieval of remotely sensed data based on low-level features. However, the deep gap between low-level features and high-level semantics concepts is a major obstacle to more effective image retrieval. Therefore, a semantics-based retrieval approach was implemented. The semantics classifiers are trained using heterogeneous features from a group of satellite images. T... View full abstract»

    Spatial database has become the dominant techniques to manage spatial data in geographical information systems, and geographic structured query language (GSQL) is the key of spatial database design and implementation. At present, GSQL for vector data has been widely studied. However, when the raster data are considered, there is little specific research. On the basis of corresponding ADTs (abstrac...
