modeling leaf area index (lai) extension of winter wheat as a function of moisture condition

the swleww computer model (soil water leaf extension of winter wheat) was developed in order to simulate the daily extension of winter wheat (triticum aestivum l. cv.ghods) leaf area as a function of soil moisture stress. the model consists of two main components: (1) the previously developed sw a tre (soil water and actual transpiration rate extended) program for simulating the soil water budg...

Seasonal changes of leaf area index (LAI) in a tropical deciduous forest in west Mexico

Light canopy transmittance and the Beer-Lambert equation were utilized to assess monthly leaf area index (LAI) of a tropical deciduous forest ecosystem on the west coast of Mexico. The light transmittance coefficient (k) was obtained by analyzing vertical leaf and light distribution in the forest canopy. An independent LAI estimate was obtained using litterfall data. The calculated k value was ...

Retrieval of a Temporal High-Resolution Leaf Area Index (LAI) by Combining MODIS LAI and ASTER Reflectance Data

This paper aims to retrieve temporal high-resolution LAI derived by fusing MOD15 products (1 km resolution), field-measured LAI and ASTER reflectance (15-m resolution). Though the inversion of a physically based canopy reflectance model using high-resolution satellite data can produce high-resolution LAI products, the obstacle to producing temporal products is obvious due to the low temporal re...
