At the AWS Askole station the CX115P Lsi-Lastem barometer is connected with measurement system (recorder, data logger) that accepts analog signals. The barometer functions according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance. The CX115P model mounts a special thermal compensation system that significantly reduces drift. Specific characteristic: Range: 800 ž 1100 hPa (1 hPa=1 mBar) Sea level correction range: -300...+2000 mt. Thermal drift: 0,01 hPa/°C (-10..+60°C) Linearity&Hysteresis: < 0,3% of the range Overload: max. 2 Pa Load resi stance: Current output types: <500W. Power consumption: 3 W Response time (T90): 1 ms Environmental limits: -25 .. +60°C Output connections: terminals Weight: 650 gr. Housing case material: Plastic Protection: IP40 Downward cable outlet

At the AWS Askole station the CombiSD DNA022 Lsi-Lastem combined wind speed-direction sensor is mounted on a 5m pole. The CombiSD sensor includes, in a single apparatus, the both transducers for measuring wind speed and wind direction. Its use simplifies the installation and the plant design in respect of the sensors with separate measurements plus giving some other advantages being smaller, lighter and cheaper. The CombiSD DNA022: sensor has a direct signal output. Frequency (Hz) for wind speed and resistance (Ohm) for wind direction. the CombiSD has low power consumption, it can be used in systems with small energy availability. The technical characteristics are: - Principle of operation: 3 cups and vane anemometer - Speed sensor: Optoelectronic disk - Direction sensor: 2000 Ohm wire potentiometer / Positioning Hall effect sensor - Housing: Heavy gauge anodised aluminium - Shaft carriers: Low-torque stainless steel bearings - Protection (vertical position): IP65 - Mechanical mounting: On 48 50 mm diameter mast - Electrical outlet terminators: IP65 watertight connector - Weight (instrument with rotors): 950 gr. The Physical and operational specification are: - damage threshold > 75 m/s - operating temperature: -30°+70°C The speed measures are specified by: - Measurement range: 0-60 m/s (using transfer function) - Threshold: 0,21 m/s - Response time (63% at 5 m/s): 0.8 s - Distance constant (delay distance) at 5 m/s: 4 m - Resolution (integration time=1s): 0.05 m/s - Accuracy & Linearity: 0,1 m/s+1%VL (readout), if connected to LASTEM data loggers. The direction measures are specified by: - Measurement range: 0 ÷ 360 - Threshold: 0,15 m/s - Response time (at 5 m/s): 0,26 s - Delay distance (at 5 m/s): 1,32 m - Damping coefficient (VDI3786): 0,21 - Transfer function: Dir(°)= 355 x R(Ohm)/2000 - Resolution: 0,1 - Accuracy: 1% FS (Full scale) - Integral linearity: 0,5%

Askole is the last village on the route to the Baltoro Glacier and K2. Its average elevation is 3000 m a.s.l., the village is on the right side of the valley and just north of the main river, on a moraine highland with a low inclination toward the river, where local people carry out little agriculture. The station is on the lower, southern part of the moraine platform, near the edge above the river, and it has open visibility toward East (valley upward), West (valley downward), South (in front of opposite side of the valley) and North (leading to the slopes of the mountain surrounding the village). The installation is located about 200 meters south from the Lorenzo Mazzoleni Dispensary in the middle of the cultivated area, protected by a resistant fencing. Geographical coordinates: Latitude: 35° 40' 50" N Longitude: 75° 48' 55" E Elevation: 3000 m a.s.l.
