This server is an on-going effort of Ecole
des Mines de Paris/Armines, Center for Energy and Processes,
to provide information on solar radiation. It is a companion to
the SoDa Service.
The item Education
is available in English and French. It comprises a series
of lectures on the climatology of the radiation over Europe.
Also available are applets Java for the course of the sun in
the sky. Units and Terminology are dealt with.
The Heliosat method converts
Meteosat satellite images into data maps of solar radiation.
The method calls upon libraries describing the solar geometry,
the satellite geometry and clear-skies models. These libraries
are freely available as sources in C as well as the method Heliosat.
The calibration
of Meteosat images is an important element for the exploitation
of large time-series of images.
By the means of the methods Heliosat, the databases
HelioClim of solar radiation (irradiation or irradiance),
were, and are, created by processing Meteosat images. These
databases run since 1985. They can be accessed through the SoDa
service. The SoDa service delivers information on solar radiation
(data, databases, algorithms, advanced applications).
Values of Linke
turbidity factor can be accessed through the SoDa Web service. The database of the Linke turbidity factor is available for the whole world.
Other services, previouly offered by the HelioClim server, such as simulations of the clear-sky irradiation, simulation
of system for hot water production, PAR computation...) are
now part of the service SoDa.
ESRA
(European Solar Radiation Atlas) is an atlas made on behalf
of the European Commission (Brussels, Belgium). The CD-ROM and
the PC-software for its exploitation are commercially available
through Les
Presses de l'Ecole des Mines de Paris. An overview of the
atlas is given here, with an emphasis on maps.
A
service is available for the control
of the quality of measurements of global irradiation. Enter your own series of data and check their plausibility.
Other servers exist whose main goals support the HelioClim initiative.
Links are given to these
servers.
