Mapping incident photosynthetically active radiation from MODIS data over China

Photosynthetically active radiation (PAR) is a key input parameter for almost all terrestrial ecosystem models, but the spatial resolution of current PAR products is too coarse to satisfy regional application requirements. In this paper, we present an operational system for PAR retrieval from MODIS data that is based on an idea proposed by [Liang, S., Zheng, T., Liu, R., Fang, H., Tsay, S. -C.,...

Parametric models to estimate photosynthetically active radiation in Spain

Different applications dealing with plant physiology, biomass production and natural illumination in greenhouses require knowledge of the photosynthetically active radiation. In absence of measurements of this flux, one must rely on parametric approaches. In this way, the radiant energy is computed using available atmospheric parameters. In the present work, we have developed a comparison among...

Mapping High-Resolution Incident Photosynthetically Active Radiation over Land from Polar-Orbiting and Geo stationary Satellite Data

Incident photosynthetically active radiation (PAR) is required by almost all terrestrial ecosystem models and many other applications. The current PAR products that are developed for climate studies have much coarser spatial resolution and higher temporal resolution and are not suitable for land applications. This article reviews stateof-the-art methods for mapping land spatial-resolution incid...

Photosynthetically active radiation: measurements and modelling

Photosynthetically-active radiation is a necessary input in applications dealing with plant physiology, biomass production and natural illumination in greenhouses. Unfortunately, a worldwide routine network for the measurement of photosynthetically-active radiation is not yet established and it is often calculated as a constant ratio of the broadband solar radiation. This ratio is affected by m...

Simultaneous Assessment of Photosynthetically Active and Ultraviolet Solar Radiation

A new dosimetric package for assessing solar radiation affecting photosynthesis in the visible and ultraviolet wavebands in plant canopies has been developed and tested. The package consists of several detectors sensitive to various wavebands between 290 and 700 nm. For photosynthetically active radiation (PAR), the dosimeter was calibrated for exposures in terms of photosynthetically active ph...
