SpaceWeather.NoaaClient

Overview

SpaceWeather.NoaaClient is an unofficial .NET client for NOAA's Space Weather Prediction Center (SWPC) JSON services.

The library focuses initially on aurora monitoring (Kp index, short-term predictions, OVATION model), and expands gradually toward full SWPC JSON coverage.

Installation

dotnet add package SpaceWeather.NoaaClient

Basic Usage

using SpaceWeather.NOAAClient;

// 1. Create an instance of HttpClient to be used for making HTTP requests.
var httpClient = new HttpClient();

// 2. Create an instance of SpaceWeatherNoaaClient, passing in the HttpClient.
var spaceWeatherNoaaClient = new SpaceWeatherNoaaClient(httpClient);

// 3. Retrieve data using the SpaceWeatherNoaaClient methods.
var kpIndex1MinData = await spaceWeatherNoaaClient.GetKpIndex1MinAsync();

Console.WriteLine("Kp Index 1-Minute Data: ");
Console.WriteLine();
foreach (var item in kpIndex1MinData.KpData1MList)
{
    Console.WriteLine($"\tTime: {item.Date}, Kp Index: {item.KpIndex}, Estimated Kp: {item.EstimatedKp}, Kp: {item.Kp}");
}
Console.WriteLine("-- End of Data --");
Console.WriteLine();
Console.WriteLine();

var kpIndexForecast = await spaceWeatherNoaaClient.GetKpIndexForecastAsync();

Console.WriteLine("Kp Index Forecast Data: ");
Console.WriteLine();
foreach (var forecast in kpIndexForecast.KpForecastList)
{
    Console.WriteLine($"\tTime: {forecast.Date}, Forecast Kp Index: {forecast.Kp}, Observation Type: {forecast.ObservationType}, NOAA Scale: {forecast.NoaaScale}");
}

Console.WriteLine("-- End of Data --");
Console.WriteLine();
Console.WriteLine();

var ovationAuroraData = await spaceWeatherNoaaClient.GetOvationAuroraLatestDataAsync();

Console.WriteLine("OVATION Aurora Latest Data: ");
Console.WriteLine($"\t Forecast Time: {ovationAuroraData.ForecastTime}");
Console.WriteLine($"\t Observation Time: {ovationAuroraData.ObservationTime}");
Console.WriteLine();

foreach (var dataItem in ovationAuroraData.DataItems)
{
    if(dataItem.Coordinates.Y > 66 || dataItem.Coordinates.Y < -66)
    Console.WriteLine($"\tLatitude: {dataItem.Coordinates.Y}, Longitude: {dataItem.Coordinates.X}, Probability: {dataItem.Probability}");
}

Console.WriteLine("-- End of Data --");

Changes

- Fixed timezone conversion issues in DateTimeOffset deserialization
- Normalized nullable types across data models for consistent JSON handling
- Implemented RtswWind1MinClient for real-time solar wind plasma data retrieval
- Resolved constructor parameter type mismatches causing deserialization failures

All integration tests now pass successfully.
