Estimation of soybean leaf wetness from meteorological variables

Intensity of Powdery Mildew in Soybean Under Changes of Temperature and Leaf Wetness

Leaf wetness within a lily canopy

A wetness duration experiment was carried out within a lily field situated adjacent to coastal dunes in the Netherlands. A within-canopy model was applied to simulate leaf wetness in three layers, with equal leaf area indices, within the canopy. This simulation model is an extension of an existing model. It appeared that in most cases leaf wetness started in the uppermost layer followed by the ...

Rapid estimation of sunflower leaf area from linear measurements

an evaluation and comparison of physical and empirical models for estimation of leaf wetness duration

leaf wetness duration (lwd) is a key parameter in agricultural meteorology. because of difficulties involved in lwd being readily measured, several methods have been developed to estimate it from weather data. among the employed to estimate lwd, those that use physical principles of dew formation plus dew and/or rain evaporation have shown to be especially transmittable and of sufficiently accu...

Meteorological Variables Associated with Stroke

To elucidate relationships between meteorological variables and incidence of stroke, we studied patients diagnosed with stroke after presenting to the emergency department (May 1, 2010-August 8, 2011). Patient demographics and medical data were reviewed retrospectively with regional meteorological data. Across 467 days, 134 stroke events were recorded on 114 days. On stroke days, maximum temper...
