This study presents high-resolution airborne geophysical estimates of the distribution of 137Cs across three areas of northern Britain and Ireland. The radiometric spectra were acquired as part of a program of modern resource and environmental surveying. The largest survey area considered covers the whole of Northern Ireland. All three data sets display some clustering on high ground together w...

The CORSAR project (Carbon Observation and Retrieval from SAR), which is supported by the UK Natural Environment Research Council (NERC), has the objective to examine polarimetric decomposition and polarimetric SAR interferometry methods for estimating the effects of canopy structure in biomass-backscatter relationships. Forest canopy height is a useful input parameter to yield models, carbon c...

[1] We report airborne organic aerosol (OA) measurements over Los Angeles carried out in May 2010 as part of the CalNex field campaign. The principal platform for the airborne data reported here was the CIRPAS Twin Otter (TO); airborne data from NOAA WP-3D aircraft and Pasadena CalNex ground-site data acquired during simultaneous TO flybys are also presented. Aerodyne aerosol mass spectrometer ...

Synthetic Aperture Radar (SAR) images are being used more extensively than ever before for geoscience applications in the moist tropics. In this investigation, a RADARSAT1-1 C-HH SAR image acquired in 1998 was used for coastal mapping and land-cover assessment in the Bragança area, in the northern Brazil. The airborne GEMS 1000 X-HH radar image acquired in 1972 during the RADAM Project was also...

This paper considers the problem of locating a stationary radar emitter from a single airborne platform making frequency measurements in the presence of aperture state uncertainty. It is shown that the location accuracy is most sensitive to aperture velocity uncertainty and that location accuracy can be improved by using a MEMS accelerometer at the aperture A decentralized method is developed f...

In the current research, we present the results from a growth detection study in young forest and mature pine-dominated forest located on poor sites. Canopy height distributions were created from small-footprint airborne laser scanner data collected over 87 georeferenced field sample plots. The size of each plot was 300-400 m. The laser data were acquired in 1999 and 2001, and none of the plots...

Multi baselinc rcpeat track interferometry (RTI) can potentially be uscd to measure both velocities and the micro topogra hy of glaciers. The Danish Center for Remote (DPC) has established a test cite for studies of glacier dynamics on the Storstreimmen glacier i n North East Greenland. DCRS has acquired RTI data over the glacier in 1994 and 1995 and ERS-112 tandem mode data are also available....

SUMMARY Various electromagnetic (EM) techniques have been developed for exploring natural resources. The novel frequency-domain semi-airborne controlled source (semi-AEM) method takes advantages of both ground and airborne techniques. It combines ground-based high-power electrical dipole sources with large-scale spatially densely covered magnetic fields measured via receivers. can survey the su...

Airborne hyperspectral data play an important role in remote sensing of coastal waters. However, before their application, atmospheric correction is required to remove or reduce the effects caused by molecular and aerosol scattering absorption. In this study, we first processed airborne CASI-1500 acquired on 4 May 2019 over Uljin coast Korea with Polymer then compared performance other two wide...
