Data source period

[m.alkour]

Hi,

How can I import updated period for a data resource, the period that I have for meteonom is 1992 to 2004. is there any problem with the accuracy of the data if it is 1992 to 2004 or i must have an update period for it to the year we are on.

Anyone can help me ?

Many thanks

When you perform a study for the forecast of a new installation, you should indeed use an average over many years. The period doesn't have much importance.

Now you can get more recent data from private companies, but this will be for pay. Remember that a simulation performed with one only (measured) year - even recent - will be less reliable than an average, due to the annual variability of the meteo data.
