This research focus on the method termed here, the Intermittent Small Baseline Subset (ISBAS), which, compared with the Small Baseline Subset (SBAS) method, appears to improve results over natural, woodland and agricultural terrain.
A new fire detection algorithm ALGO3, has been tested and validated for ATSR-1/-2 and AATSR. This extends the ATSR World Fire Atlas (WFA) to 21 years of night-time fire series.
The Santorini caldera has been a source of numerous eruptions and tsunamis in the past with the most recent seismic sequence ending in 1950 .Since then, Santorini volcano was in a "quiet" phase, with insignificant deformation and limited seismic activity.

Remote sensing applications benefit from the use of data fusion approaches based on spectral unmixing, which have proven their value for delivering spectrally consistent fused images while reducing the mixed pixel problem. In this study the scientists propose a multi-temporal setting of the algorithm that is applied to full MERIS and Landsat TM time series. The final goal is to complete or fill gaps in the Landsat time series by using MERIS data with more frequent coverage. Hence obtaining consistent time series at high spatial resolution and with the enhanced spectral properties of MERIS.
The availability of light in the water column and at the seabed determines the euphotic zone and constrains the type and the vertical distribution of algae species. Light attenuation is traditionally quantified as the diffuse attenuation coefficient of the downwelling spectral irradiance at wavelength 490 nm (Kd490) or the photosynthetically available radiation (KdPAR).
In order to prepare for the exploitation of Sentinel-2 type of time series, the European Space Agency, in collaboration with RapidEye, collected an unprecedented time series from February to June 2013 with a 5 day revisit at high resolution over 14 selected sites around the world.
