Hi all,

The Real-Time Weather Converter tool for creating Actual Meteorological
Year (AMY) files for North Europe have been updated.

News for version 2.1:

- Solar radiation data can now be retrieved from an arbitrary
coordination point covered by the STR?NG modeling system. These data can
for example be used for creating customized weather files by combing them
with site-specific measurements of temperature and humidity and wind and
atmospheric pressure data from the nearest official weather station.

News for version 2.0:

- All data from ISD is available, also data marked as "Additional". If
you tried the tool before but didn't get any data for your station, you
should now be able to get usable data for most locations.
- A new server that maps data from the SMHI server. Now retrieval time
is just a few seconds for one year of solar radiation data. AMY-files can
now be created in under a minute.
- Missing data points are visualized graphically.

The tool was made as part of my MSc degree project at M?lardalens
University, Sweden. It uses observed actual weather data from the
Integrated Surface Database (ISD), http://www.ncdc.noaa.gov/oa/climate/isd,
and modeled solar radiation data from STR?NG, http://strang.smhi.se.

Roughly, the tool covers most of Europe excluding south Europe. Long-term
coverage is from 1 of January 1999 to up to date for the northernmost area,
the southern area is covered from 1 of June 2006 (see website for map).

The quality of the solar radiation data from STR?NG varies in the
geographical dimension. Roughly the model gives good result for Sweden and
Central Europe, but underestimates for ocean coast near areas like UK,
Norway etc. The model does underestimate as well for the Baltics, northern
Finland and some high altitude sites. There's a validation figure (for
Google Earth) at the tools homepage in the help section.
