    public long utc_offset_seconds { get; set; }

    public string timezone { get; set; }
    public string timezone_abbreviation { get; set; }
    public string elevation { get; set; }
    
    Public class Hourly_Units {

         public string temperature_2m { get; set; } 
    }   
    Public class Hourly {
         public List<string> time { get; set; }
    }
