Weather data is everywhere: on the morning news broadcast, your phone, newspapers, websites, and smart home devices. Ever wonder exactly where all these different weather sources get their information from? This post explores the key weather data sources and how they contribute to our understanding of atmospheric conditions.
Reliable weather data is crucial in forecasting, climate research, and disaster preparedness. Weather data collection relies on diverse technologies and methods, ranging from surface-based stations to satellites orbiting the Earth. These data sources work together to create accurate forecasts and climate models, helping industries, governments, and individuals make informed decisions.
Federal and global organizations provide weather data in a variety of forms. These include weather-centric organizations like the US National Oceanic and Atmospheric Association (NOAA), European Centre for Medium-Range Weather Forecasts (ECMWF), UK Meteorological Office (UKMET), and space agencies such as the US National Aeronautic and Space Association (NASA), Japan Aerospace Exploration Agency (JAXA), and Brazil's National Institute for Space Research (INPE).
Weather Data at a Single Location
Surface Weather Stations
One of the most fundamental sources of weather data is surface weather observation stations. These stations are equipped with sensors that measure variables including temperature, humidity, wind speed, wind direction, atmospheric pressure, and precipitation. Networks of these stations exist globally, operated by organizations like the National Weather Service (NWS) and the World Meteorological Organization (WMO). The Automated Surface Observing Systems (ASOS) is one such program in the United States that provides continuous real-time weather observations. Weather station networks encompass a diverse range of data collection systems, including road weather sensors, river monitoring stations, and personal weather stations strategically placed in residential areas worldwide.
Weather Data from the Ground to the Sky
Weather Balloons (Radiosondes)
Meteorologists use weather balloons to gather data from the upper atmosphere. These balloons are released twice daily from hundreds of locations worldwide - including NOAA's National Weather Service (NWS) offices. Each balloon's instrumentation measures temperature, pressure, humidity, and wind speed at different altitudes. The balloons' data is critical for understanding atmospheric stability, detecting jet streams, and predicting storm development. Meteorologists have been launching weather balloons to capture atmospheric weather information for over 150 years.
Weather Data from Radio Waves
Weather Radar
Weather radars use radio waves to detect precipitation, storm intensity, and wind patterns. Doppler radar, for example, is widely used to track severe weather events like thunderstorms and tornadoes. It works by emitting pulses of radio waves and analyzing how they scatter when they encounter precipitation. The National Weather Service operates the NEXRAD radar network, which provides high-resolution storm tracking and warnings. While some weather radars are stationary, others are installed on vehicles like the Center for Severe Weather Research (CSWR) Doppler on Wheels (DOW). These mobile units allow for data to be collected that may be missed from traditional single-location radars.
Weather Data from Space
Satellites and Remote Sensing
Satellites provide a global perspective on weather patterns by capturing data on cloud cover, sea surface temperatures, atmospheric moisture, and even pollution levels - just to name a few. Agencies such as NOAA, NASA, and JAXA operate geostationary and polar-orbiting satellites that monitor weather. These satellites use remote sensing technology, including infrared and microwave sensors, to detect weather phenomena from space. Additionally, private satellite companies are quickly entering the satellite space.
Weather Data from the Air
Aircraft-Based Observations
Commercial aircraft contribute to weather data collection through systems like the Aircraft Meteorological Data Relay (AMDAR) and the Meteorological Data Collection and Reporting System (MDCRS). These systems measure atmospheric pressure, temperature, and wind speed during flight, offering valuable insights into conditions at different altitudes. Aircraft data can significantly improve forecast accuracy, especially for mid-altitude weather predictions. Specialized hurricane hunter aircraft have been flying directly into storms since 1946. These aircraft gather critical data on wind speeds, pressure, and storm structure, aiding in hurricane forecasting and preparedness.
Weather Data from Across the Seas
Ocean Buoys and Ship Reports
Marine observations are essential since oceans cover vast portions of the Earth's surface. Anchored and drifting buoys measure sea surface temperature, wave height, and atmospheric pressure. These buoys and ship-based observations provide crucial data for tracking hurricanes and ocean temperatures and understanding global climate patterns. Buoy information for the United States and other international partners are primarily managed by organizations like NOAA National Data Bouy Center (NDBC).

Citizen Science and Crowdsourced Data
In recent years, crowdsourced weather data has become increasingly valuable. Networks of personal weather stations, such as those integrated with services like Weather Underground, Tempest, Davis, and Ambient, contribute hyper-local observations that enhance meteorological analyses. Additionally, mobile applications and IoT devices allow citizens to report real-time weather conditions, further enriching data availability. Take mPING, for example, a NOAA-funded crowdsource weather reporting app.
Weather Data Really is All Around
Weather data originates from a vast network of ground-based, airborne, and spaceborne instruments. Each data source plays a critical role in providing accurate, timely weather information that supports forecasting, research, and emergency preparedness. As technology advances, the ability to collect and analyze weather data will continue to improve, leading to even more reliable predictions and deeper insights into our planet's climate.
