Thermography and Sonic Anemometry to Analyze Air Heaters in Mediterranean Greenhouses

Thermography and Sonic Anemometry to Analyze Air Heaters in Mediterranean Greenhouses

The present work has developed a methodology based on thermography and sonic anemometry for studying the microclimate in Mediterranean greenhouses equipped with air heaters and polyethylene distribution ducts to distribute the warm air. Sonic anemometry allows us to identify the airflow pattern generated by the heaters and to analyze the temperature distribution inside the greenhouse, while the...

Sonic Anemometry to Measure Natural Ventilation in Greenhouses

The present work has developed a methodology for studying natural ventilation in Mediterranean greenhouses by means of sonic anemometry. In addition, specific calculation programmes have been designed to enable processing and analysis of the data recorded during the experiments. Sonic anemometry allows us to study the direction of the airflow at all the greenhouse vents. Knowing through which v...

A Networked Two-Dimensional Sonic Anemometer System for the Measurement of Air Velocity in Greenhouses

The experimental study of air movement induced by natural ventilation in greenhouses requires a system to measure the air velocity "eld. A networked, two-dimensional sonic anemometer system was developed for simultaneous measurement of the instantaneous air speed and direction at 12 locations. The system performance was tested and validated against a mass #ow controller and a commercial, three-...

Exposure to Air Pollution and Pregnancy Outcomes in the East Mediterranean Region: a Systematic Review

The East Mediterranean region suffers from high levels of air pollution which has a negative impact on pregnancy outcomes. This work systematically reviews the epidemiological evidence on maternal exposure to air pollution and adverse pregnancy outcomes in the region. Relevant papers and reports published between 2000 and 2014 were searched. Combinations of search terms including countries, exp...
