  text: "Access to precise meteorological data is crucial to be able to plan and install
    renewable energy systems \r\nsuch as solar power plants and wind farms. In case
    of solar energy, knowledge of local irradiance and air temperature \r\nvalues
    is very important. For this, various methods can be used such as installing local
    weather stations or using \r\nmeteorological data from different organizations
    such as Meteonorm or official Deutscher Wetterdienst (DWD). An \r\nalternative
    is to use satellite reanalysis datasets provided by organizations like the National
    Aeronautics and Space \r\nAdministration (NASA) and European Centre for Medium-Range
    Weather Forecasts (ECMWF). In this paper the \r\n“Modern-Era Retrospective analysis
    for Research and Applications” dataset version 2 (MERRA-2) will be presented,
    \r\nand its performance will be evaluated by comparing it to locally measured
    datasets provided by Meteonorm and DWD. \r\nThe analysis shows very high correlation
    between MERRA-2 and local measurements (correlation coefficients of 0.99) \r\nfor
    monthly global irradiance and air temperature values. The results prove the suitability
    of MERRA-2 data for \r\napplications requiring long historical data. Moreover,
    availability of MERRA-2 for the whole world with an acceptable \r\nresolution
    makes it a very valuable dataset."
