Basin-wide actual evapotranspiration estimation using NOAA/AVHRR satellite data
(2005)The present study elaborates on the estimation of actual evapotranspiration at watershed scale using mathematical models and remote sensing techniques. A water balance model was updated and used to simulate runoff from a ... -
Convective and ventilation transfers in greenhouses, part 2: Determination of the distributed greenhouse climate
(2002)In this paper, the characterisation and modelling of the most relevant convective transfers contributing to the description of the distributed greenhouse climate are studied in detail. After a brief review of the equations ... -
Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ... -
Effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity
(2014)The effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity were investigated in a Mediterranean climate (Eastern Greece) under three covering materials (i) a pearl insect-proof ... -
Greenhouse microclimate and soilless pepper crop production and quality as affected by a fog evaporative cooling system
(2007)The influence of greenhouse! humidity control on greenhouse microclimate, crop transpiration rate, and yield and. fruit quality of a soilless grown pepper crop was studied in a greenhouse located at the coastal area of ... -
Influence of greenhouse ventilation regime on the microclimate and energy partitioning of a rose canopy during summer conditions
(2001)The influence of the greenhouse ventilation regime (natural or forced ventilation) on the energy partitioning of a well-watered rose canopy (Rosa hybrida, cv. First Red) was investigated during several summer days in warm ... -
INFLUENCE OF HEATING SYSTEM ON GREENHOUSE MICROCLIMATE DISTRIBUTION
(2010)Convective and radiative heat transfer from heating systems significantly determines greenhouse microclimate during the cold period of the year. These mechanisms are complicated because they combine free and forced convection ... -
Influence of leaf area index on canopy energy partitioning and greenhouse cooling requirements
(2002)Canopy transpiration, which represents the major cooling process in greenhouses, depends strongly on the crop leaf area index I-LA. In this paper, the influence Of I-LA on canopy and greenhouse energy balance of a soilless ... -
Leaf boundary layer conductance in ventilated greenhouses: An experimental approach
(2007)Improving the design, control and management of greenhouse ventilation systems requires a better insight into the coupling and feedback mechanisms between the crop, the internal atmosphere and the outside atmosphere. The ... -
Response of an eggplant crop grown under Mediterranean summer conditions to greenhouse fog cooling
(2009)The effects of greenhouse cooling using a high-pressure fog system on greenhouse microclimate and on eggplant (Solanum melongena) crop response were studied at the coastal area of western Greece. Measurements were carried ... -
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ...
