What is the source of the data used in the forecast process?

WeatherPlanner depends on several sources for information: its own proprietary scientific technology, international weather services, and the National Weather Service (NWS).

WeatherPlanner uses historic weather information as part of its forecasting process and maintains one of the most extensive forecast databases ever assembled by a private weather company.

Our greatest source of information is the National Weather Service and National Climatic Data Center (NCDC) which provides WeatherPlanner with data for the United States and international data. That information includes historical and current temperature values, precipitation and snowfall amounts, and satellite and radar intelligence. For locations outside the United States. WeatherPlanner relies on many meteorological services from other countries.

NWS is the standard for all weather companies.

The National Weather Service sets the standard for data collection that every other meteorological service seeks to emulate. NWS's responsibilities fall into many areas which include collecting weather observations from sites around the country, developing and monitoring sophisticated weather models, and providing storm warnings and advisory services for the public.

Making its data available to the public is also part of the NWS mission, WeatherPlanner uses this service to further interpret the information, making it more understandable and accessible to the general public.
