European air quality data
The KMZ files below show the air quality in Europe as measured from the monitoring networks of each European country. Sites are represented in green if they comply with the European Union directives on air quality on sulphur dioxide (SO2), particulate matter with aerodynamic size up to 10 micron (PM10), ozone (O3), nitrogen dioxide (NO2), nitrogen oxides (NOX), benzene (C6H6) and lead (Pb). In red if they do not. Only values measured at monitoring stations with more than 75% of valid data are represented.Once in Google Earth, zoom and click on points to get information on air quality.

Wind roses
The KMZ files below can be displayed with Google Earth or directly imported within a Google map in your web pages (as the exemple here shown for Montreal, Canada). They show the wind roses in some places of the world. All the wind roses have been produced using the WindRose PRO software starting from processed METAR data.

Global wind power
A global wind power estimation has been carried out by Enviroware using the GDAS (Global Data Assimilation System) data for years 2007 and 2008. The wind power is estimated at 50 m and 80 m above ground level starting from wind speed at 10 m above ground and applying a logarithmic vertical profile. The roughness length needed in the logarihmic profile has been obtained from the Global Land Cover Facility.
The operating probability and the annual specific yield have been calculated for a hypothetical wind turbine with a rated power of 2000 kW, a blade diameter of 80 m, a cut-in wind speed of 3.5 m/s and a cut-out wind speed of 25 m/s. Wind turbines similar to this hypothetical one are, for example, the Gamesa G80, the REpower MM82, and the Vestas V80-2.0. The wind power class does not depend on the particular wind turbine, but only on the average wind speed.<7p>
