Correction of sun glint effect on MIVIS data of the Sicily campaign in July 2000
MIVIS water leaving radiance sun glint path radiance probability density function
2015/9/7
To assess the suspended and dissolved matter in water in the visible and near infrared spectral regions it is necessary to estimate with adequate accuracy the water leaving radiance. Consequently radi...
Strain patterns along the Kaparelli–Asopos rift (central Greece) from campaign GPS data
GPS Strain Kaparelli Central Greece
2015/8/14
We present results from four GPS campaigns in the broader Kaparelli–Asopos area in central Greece. This area is undergoing extension as demonstrated by seismological, geodetic and geological data. The...
