NSG Weather

Network Services Group is a proud contributor of weather data to the following:

APRSWXNET (Automatic Position Reporting System as a WX NETwork)
The Automatic Position Reporting System (APRS tm) is a part of ham radio that provides an ideal way for weather station operators to distribute their weather data much further than the regions within their transmitter range. APRS was originally intended for position information data but actually provides a means for automatic transmission of all sorts of digital data. This is especially true now that the original APRS packet radio concept has been enhanced to include the capabilities of the Internet. The reporting of citizen weather data is a particularly useful application of the APRS Internet Service (APRS-IS).

Citizen Weather Observer Program (CWOP)
The Citizen Weather Observer Program (CWOP) is a group of ham radio operators and other private citizens around the country that have volunteered the use of their weather data for education, research and use by interested parties. The APRS-IS collects weather data transmitted from individual stations and communicates these data to the amateur radio findU server where the data are organized and made available to the MADIS Program at 15-minute intervals.

The CWOP data also go to the MADIS Quality Control and Monitoring System (QCMS) which checks data quality using a variety of techniques. Based on these checks, data may be declared questionable. Occasional questionable data is normal. However, a high percentage of questionable data may indicate instrument or siting problems.

The results of this quality checking are then made available to the station operators on the CWOP Data Quality web page. This feedback to the weather station owners can alert them when a problem has developed. The goal here is to provide tools for station owners to help them keep the data quality high so that the data can be widely used with confidence.

Meteorological Assimilation Data Ingest System (MADIS, NOAA)
The Meteorological Assimilation Data Ingest System (MADIS) is dedicated toward making value-added data available from the National Oceanic and Atmospheric Administration's (NOAA) Earth System Research Laboratory (ESRL) Global Systems Division (GSD) (formerly the Forecast Systems Laboratory (FSL)) for the purpose of improving weather forecasting, by providing support for data assimilation, numerical weather prediction, and other hydrometeorological applications.

This data is also used to initialize the Advanced Regional Prediction System (ARPS) , MM5 , and Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPStm) forecast models.

Weather Underground
wunderground.com is most likely the best internet weather site. It allows you to not only receive accurate weather forecasts and alerts, but it allows you to select a weather station nearest to you to receive weather forecasts closest to your location.
