The archive also includes meteorological observations for a multitude of climatic and atmospheric variables at various time steps and periods. The archive contains continuous hourly records of the main climatic variables, such as air temperature, maximum and minimum daily temperature, atmospheric pressure, relative humidity, and wind speed and direction. Additionally, precipitation and atmospheric data, such as sunshine duration, cloudiness, visibility, etc., are included. Daily time series of the most important climatic variables are also included in the repository of the National Network for Climate Change and its Impacts (CLIMPACT – https://data.climpact.gr/dataset).
