This dataset comprises high-resolution historical time series (hourly frequency) from automatic weather stations covering all states of Brazil. Included Variables: Thermodynamics: Air Temperature (instantaneous, max, and min), Relative Humidity (instantaneous, max, and min), and Dew Point (instantaneous, max, and min). Dynamics & Wind: Atmospheric Pressure (station level, max, and min), Wind Direction, Wind Speed, and Maximum Gust. Others: Total Precipitation (rainfall) and Global Radiation. These data are suitable for climate modeling, renewable energy potential assessment (wind and solar), hydrological analysis, and precision agriculture.
