The in-situ measurement campaigns are complementary to the remote observations activity and they are used to make
an intercalibration at the local scale of such satellite data/products. Considering that along the Ionian coast there are
the mouths of five rivers: Sinni, Agri, Cavone, Basento and Bradano, a sampling grid was carried out which includes a series
of transects perpendicular to the line of coast at the mouths of rivers, and one parallel to the coastline.
Between 18 and 19 April 2013, a first measurement campaign in-situ was carried out with two particular aims: the acquisition and measurement of
data and parameters provided and the assess of timing, logistical difficulties and costs necessary to make possible the in-situ activity, informations
that will be useful for the subsequent campaigns assessment.
