main land use on this plateau (2 km

) and are traditionally managed for hay pro-
duction with low mineral fertilization and one cut per year in mid-July. Soil can
be classified as a Typic Hapludalfs, lyme loamy, mixed, mesic with the following

2.2.14 Negrisia (IT-Neg)
The site is located in North-Eastern Italy in a commercial vineyard located in
Negrisia di Ponte di Piave (45.74756° N; 12.44673° E, 11 m.a.s.l.). The climate
is mediterranean, with average annual precipitations of 833 mm and an average
annual temperature of 13.1 °C. The station, set up in July 2005, is in the center of
a one single 25 ha plot. The terrain is quite flat and both soil and canopy are very
homogeneous and thus suitable for both micrometeorological and remote-sensing
approaches. The vineyard is mainly composed of
Vitis vinifera

rootstock. The vines were planted in 1992 in north-south ori-
ented rows (500-600 m long) 2.50 m apart. Plant spacing on the rows is 1.30 m,
resulting in a density of 3,076 vines per hectare. Vines were grown with a sin-
gle trunk trained to spur-pruned cordon, at about 1.7 m aboveground, for vertical
shaker harvesting. The floor is grass covered and a 1 m wide strip on the rows is
chemically treated. The silty-clay loam soil (International textural classes), classi-
fied as Vertic Eutrudent (FAO
2008
), is >1 m deep and highly homogeneous within
the study site, rich in organic matter (about 18.2 g kg
−
1
) and with an average pH
of 7.7. The vineyard receives standard management. Maximum canopy height was
kept at 2.70 m, and no foliage could be found below the cordon. Maximum LAI,
monitored both by direct and by indirect methods, ranges from 2.2 to 2.5.
2.2.15 Noè (IT-Noe)
The No￨ site is located within a nature reserve called “Le Prigionette” (40.60613°
N; 8.15146° E, 27 m.a.s.l.). The area is part of the Capo Caccia peninsula, in
North-Western Sardinia, near the town of Alghero. The nature reserve, with a sur-
face area of approximately 1,200 ha, is delimited by a cliff dropping to the sea on
the north-western and western boundaries.
The climate is Mediterranean, semiarid with a warm summer, mild winter,
and a prolonged water shortage from May through September. The averages for
annual, minimum and maximum temperatures are respectively 15.9, 7.0, and
28.0 °C. The average annual thermal excursion is about 14 °C (10 °C in January
and 24 °C in August). The average annual precipitation is 588 mm, mainly con-
centrated during the spring season. In the course of the autumn intense rainstorms
often occur with high runoff and low water storage.
