The first model assumes spherical particles with the composition of each particle being a uniform mixture of ice, water, and air. The second model assumes concentric spherical particles. Each particle has a snow core covered with water. The computed results are compared with the experimental results obtained by a dual-frequency air-borne radar in the case of tropical storm which was accompanied by bright-band. Three negative exponential type drop-size distributions, i.e. Marshall and Palmer distribution, Joss drizzle distribution, and Joss thunderstorm distribution, are used in the computations. The best agreement between computations and experimental results is obtained by the first model assuming Joss thunderstorm drop-size distribution.<<ETX>>","PeriodicalId":312260,"journal":{"name":"Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127290756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparison of a map of surficial geology with an image of Landsat TM channel 7 shows that carbonate rich tills match the white (high reflectance) part of the image. These carbonate tills were carried by glaciers from lowlands to the east of the peninsula. The tills vary in thickness from less than one meter to more than 10 meters and effectively screen out radiation form the underlaying granitoid bedrock. A potassium map, derived from airborne gamma ray spectrometry, can be adequately explained only if the blanketing of the till, which overlies granitic bedrock, is taken into account. Bedrock geology, especially in glaciated regions, cannot be adequately mapped by Landsat and airborne spectrometry unless the nature of the surficial geology is well understood.<<ETX>>","PeriodicalId":312260,"journal":{"name":"Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132381088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dominant gravity wavelengths exhibit a systematic lengthening with penetration distance into the MIZ for three different regions examined. The extracted dominant wavelengths were analyzed using a linear least square fit with penetration distance and a flexure-gravity wave model to estimate mean ice thickness. The extracted mean thickness varies from about 1/spl plusmn/0.4 m near the ice edge to approximately 2/spl plusmn/0.4 m near the deepest detectable penetration of the waves, about 20 km. These thicknesses are in agreement with 31 in-situ measurements taken in the Fram Strait MIZ within two weeks of the SAR measurements.<<ETX>>","PeriodicalId":312260,"journal":{"name":"Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium","volume":"152 3-6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132846016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the environmental monitoring, in order to detect the changes in multi-temporal images, it is necessary to correct these data to a peculiar reflectance of the target, or convert them into the same scale. Atmospheric correction is one of the most important and complicated kinds of correction. A simplified alternative method has already been proposed and successfully applied to the Thematic Mapper (TM) data of the Earth resource observation satellite LANDSAT. In this paper, the alternative atmospheric correction method was extended and applied to the Advanced Very High Resolution Radiometer (AVHRR) on board of NOAA satellites. Atmospheric correction for the Normalized Difference Vegetation Index (NDVI) estimation is also discussed.<<ETX>>","PeriodicalId":312260,"journal":{"name":"Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132981009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The image shows sea surface manifestations of atmospheric boundary layer rolls generated by heating of a cold air mass moving over a warm sea surface. This is inferred from the orientation of the quasi-periodic sea surface pattern which is aligned approximately with the wind direction, from the ratio of the wavelength of the pattern to the height of the boundary layer, which is close to its theoretical value of 2.8, and from the conditions encountered in the atmospheric boundary layer as measured quasi-simultaneously by radiosondes. For the first time, quantitative estimates of variations of the wind velocity at the sea surface associated with the atmospheric rolls are extracted from a spaceborne radar SAR image.<<ETX>>","PeriodicalId":312260,"journal":{"name":"Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127880216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
