Objective
The objective of the project is to create an European Light-dosimeter network which can provide, through the internet, data on light fluxes around Europe in real time to all interested users.
In contrast to the planned or existing networks which measure the spectral distribution of solar radiation, the
European Light Dosimeter Network (ELDONET) is intended to satisfy the interests and needs of the scientific
community involved in the study of the effects of solar radiation. Our aim is to build an accurate, but low cost
network.
The instruments operate with three channels (UV-B, 280-315 nm; UV-A, 315-400 nm; PAR, 400-700 nm) based
on custom-made filters and specific photodiodes. They will be amplified and processed together with the
temperature and pressure (for underwater measurements) data and send to a computer running under
WINDOWS which allows data storage, graphical presentation as well as calculation of hourly, daily and weekly
doses. The ELDONET stations will be arranged along a north-south transect from Northern Sweden (Abisko,
69 N) to the Canary islands (Gran Canaria, 27 N) and extend from east to west from Greece (Korinth, 23
E) to the Canary Islands (17 W); we plan to include Iceland (22 W) and Wales as locations (4 W) in the
near future to cover the major light climate areas in Europe. Other stations are encouraged to join the network,
which will be very easy, as the hardware and installation costs are comparatively low.
Some stations will be installed at high altitudes (Zugspitze, Germany and Sierra Nevada, Spain) to measure the
significantly higher UV-B levels compared to lower altitudes. Land-based instruments are installed at all sites;
in addition, at some sites water-proof versions are installed in the water column to detect the irradiance which
is experienced by the organisms growing at that specific depth. Precision and reliability strongly depend on frequent calibration against standards (Optronic 752). Also the
dependence on temperature and solar angle will be analyzed and corrected for.Even though the instruments
are designed to be low cost, a high amount of precision is intended; therefore one important aspect of the project
is the identification and remedy of potential sources of error. The existing hardware and software prototypes
have been rigorously tested in the lab and at various sites under different climatic conditions to minimise
measurements errors. This process will continue during the installation and operation of the network. The local
computers will be responsible for control monitoring and maintenance of the local resources and they must
automatically detect severe errors in data acquisition and eliminate or indicate them before transmission.
File storage and handling as well as transmission to the central data server (Pisa) will be done by automatic
protocols. The central server in Pisa will be responsible for data storage and processing. Most sites will be
interconnected via INTERNET and the data files will be automatically transferred every day at the end of the
daily acquisition via FTP or, if it is not available, via E-mail on the hard disk of the central server. Stations
in remote areas with no INTERNET connection will send the data on disk to the data manager on a regular
basis.
The set of raw data if the various stations will then be made available at no cost to the scientific community via
anonymous FTP, Gopher, E-mail and the World Wide Web (WWW). Thus, in contrast to other networks, the
irradiance and dose data will be available on an instant basis to the scientific community on the World Wide
Web. For this purpose a HTML-home page will be created indicating that the data are made available by the
European Community. Each year the raw data from the stations will be copied onto CD ROMs which will then
be made available to every interested user.
