Check the above link to access and download lot of Italy weather history parameters including:

Temperature (2m)

Relative humidity (2m)

Pressure (mean sea level)

Precipitation amount

Snowfall amount

Total cloud cover

Low, mid and high cloud cover

Sunshine duration (minutes)

Solar radiation

Wind speed and direction (10m)

Wind speed and direction (80m)

Wind speed and direction (900hPa)

Wind gusts (10m).

Hope could help.

Dear Gareth,

obviously your need for wind data raises from a specific purpose.

Generally speaking, I think that wind generation is still a tricky point for weather generators, due to the fact that it could be properly generated just via spatially explicit physical models of the atmosphere.

Moreover, models need to be properly parameterized, so there is the primary need to retrieve observed data to perform the task.

Anyway, I would suggest you to ask regional meteorological system (https://www.arpae.it/) for data you need.

Try the work by Lawan et al. I have put in a link to it. https://pdfs.semanticscholar.org/675f/a12de3508020f41dcc36e40effe4760d1c92.pdf

Hi Gaieth,

I don't know if you can calculate evaporation, but I am sure you can't estimate transpiration correctly from the state-of-the-art leaf boundary layer parameterization and the similarity theories employed in the models are not sufficient, and not to mention the quality of wind data.

Cheers,

Kishore

Dear Dr.Mehdizadeh, thank you for the link

Dear Mr.Wörner , thank you. That is very interesting. Do you know where I can data before 1981?

Hi Ghaieth

Artificial neural network is a popular method for wind speed and wind power forecasting. You can find wind power, wind speed and wind direction data of a Spanish wind farm. However, the data starting from 2004.

Thank you Qin Chen , But I need data starting from the seventies
