Relationship between net radiation and solar radiation for semi-arid shrub-land

چکیده

This paper presents the results obtained by analysing a set of measurements of surface radiation balance components at a semi-arid location in SE Spain. The relationships between net and surface shortwave radiation were explored by using 38 months of 5 min surface radiation. The study area is covered by sparse clumped shrub-land of different species, although close to the radiometric station Retama sphaerocarpa is dominant. After this study, it is evident that a single model based on surface shortwave radiation could provide appropriate estimates. The inclusion of albedo information provides a slight improvement on the estimation model. The use of seasonal models provides an appreciable improvement, while the benefits of including cloud information are only marginal. © 2003 Elsevier Science B.V. All rights reserved.

Solar Radiation Estimation from Rainfall and Temperature Data in Arid and Semi-arid Climates of Iran

Precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. Therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. This paper is about an evaluation of eight models foran estimation of daily solar radiation (Q) from ...

Application of SIMETAW simulation model for prediction of climate parameters in different regions of Iran

So far, several models have been proposed for estimating different climate parameters, but due to the lack of valid and long-term data in some meteorological stations, some models have been difficult to use. The SIMETAV V.1.0 model has been developed in cooperation with the University of California Davis and the Water Resources Authority of California in 2005. The SIMETAW model is a new and inn...

A machine learning approach to estimation of downward solar radiation from satellite-derived data products: An application over a semi-arid ecosystem in the U.S.

Shortwave solar radiation is an important component of the surface energy balance and provides the principal source of energy for terrestrial ecosystems. This paper presents a machine learning approach in the form of a random forest (RF) model for estimating daily downward solar radiation flux at the land surface over complex terrain using MODIS (MODerate Resolution Imaging Spectroradiometer) r...
