This is a .net wrapper to the NCDC Climate Data Online (CDO) api.

You will need an access token. You can request one here.

var client = new ClimateDataClient(httpClient, "<your_token>", "<user_agent>")

// Construct a request object for "GHCND" data from the station "GHCND:USC00425837" for dates between 1908-05-01 and 1908-06-01
var dataRequest = new DataRequest("GHCND", new DateTime(1908, 5, 1), new DateTime(1908, 6, 1))
    .WithStations("GHCND:USC00425837");

// Get data
var response = client.GetData(dataRequest);
