English to Spanish Tech/Engineering Energy / Power Generation wind turbines / wind farm

Agradecería sugerencias de traducción para "met masts" en este contexto. Fase de evaluación de sitio previa a la instalación de turbinas eólicas:

"• Identify the wind turbine positions that are suitable for power performance measurements, in case these have not been selected by the Customer or the wind turbine manufacturer;
• Determine the number of met masts required for measurements and their corresponding locations;
• Recommend a measurement topology and check whether a single permanent met mast may be shared for measurements at two wind turbines;
• Determine the wind direction sectors that are free of obstacles and perturbations to the flow, at both the wind turbines selected for measurements, as well as at the met masts;
• Determine the need for temporary wind speed measurements to calibrate the power curve measurement, which must take place prior to the wind turbine installation."
