1 . Measurement platforms :

• Building of measurement for monitoring outflows ( stilling of reinforced concrete and hydrological instrumentation to the closing section of the stream.

• Within a fenced area , you have installed a metal tower 16 m high . At the top you have installed a telescopic pole steel to reach 9 m above the vegetation cover . The tower was installed most of the micrometeorological sensors , while on the pole additional sonic anemometer has been installed and the air sampling tube for the measurement of concentrations in the air of carbon dioxide and water vapor. In order to ensure the continuity of power to the energy measurements performed , were installed four solar panels ( 2 to 110 W and n . 2 70 W ) to 16 m in height , together with 8 batteries 6 V x 240 Ah .

2 . Instrumentation in-situ :

• Hydrological Instrumentation basic ( idrometrografo ) , to be strengthened

• Instrumentation to measure the exchange of CO2 and water vapor follows: gas analyzer ' closed path' fast-response LiCor 7000 ( LiCor , Lincoln , Nebraska - USA) ; CSAT -3 sonic anemometer ( Campbell Scientific , Logan, Utah - USA ) ; pump " brushless " by 11 l min- l ( KNF Neuberger GmbH , Germany)

• micrometeorological sensors for the measurement of:

a. Net radiation sensor ( Middleton , Brunswick, Victoria, Australia) ;

b . Components of long-wave (infrared) and shortwave ( global radiation ) ( radiometer CNR1 , Kipp & Zonen ) ;

c . Photosynthetically active radiation ( PAR sensor , LiCor , Lincoln , Nebraska - USA) ;

d. Temperature and humidity of the air above the canopy , to 2 m in height and soil temperature at 5 and 20 cm depth ( PT100 sensors , MICROS Srl , Treviso , Italy) ;

and . Soil heat flux ( REBS sensor , Campbell) ;

f . 0-30 cm soil water content ( CS615 , Seattle, Washington, USA) ;

g . Rain gauge Voices ( sensor MICROS , Italy).

• Data- logger CR 5000 ( Campbell Scientific) is used for the collection of data at high frequency (20 Hz) for the measurement of turbulence and flows, both for the collection of micrometeorological data.
