GOES-16 is ready to embark on another major milestone.
Since NOAA’s GOES-16 satellite lifted off on November 19, 2016, a team of scientists and engineers from both NOAA and NASA, has been working around the clock to power on the satellite’s advanced instruments and to get their data back to Earth. Now that the data has begun to flow, GOES-16 and its team of experts on the ground are ready to embark on another major milestone—the GOES-16 Field Campaign.

During this three-month campaign, a team of instrument scientists, meteorologists, GOES-16 engineers, and specialized pilots will use a variety of high-altitude planes, ground-based sensors, unmanned aircraft systems (or drones), the International Space Station, and the NOAA/NASA Suomi NPP polar-orbiting satellite to collect measurements across the United States.
From arid desserts and areas of dense vegetation, to open oceans and storms exhibiting lightning activity, these measurements will cover nearly everything NOAA’s GOES satellites see from their orbit 22,300 miles above the Earth.
Although these data are collected on Earth, GOES-16’s operators will obtain similar measurements of the same locations using two of the satellite’s most revolutionary instruments—the Advanced Baseline Imager and the Geostationary Lightning Mapper. The data sets will be analyzed and compared to the data collected by the planes, drones, and sensors to validate and calibrate the instruments on the satellite.
Making Data Accurate

Data from NOAA’s GOES satellites are used 24 hours a day, seven days a week for everything from flight plan forecasting and air quality alerts to potentially life-saving severe storm and tornado warnings. They provide vital information to support storm tracking, seasonal predictions, drought outlooks, and space weather predictions.
NOAA’s mission is to ensure that data from its satellites are precise, accurate, and widely available, so before GOES-16 becomes operational, it must go through an exhaustive testing phase, wherein its instruments are checked and re-checked using measurements from a vast range of verified sources.
When the testing is complete, all of the GOES-16 Field Campaign information will be permanently stored as reference data at NOAA’s National Centers for Environmental Information.
Launching a Field Campaign

This is the first NOAA satellite-focused field campaign since GOES-8 launched in April 1994. In many cases, the satellite’s predecessor is used to ensure that the new satellite is taking accurate measurements. For example, when NOAA launched the Jason-3 ocean altimetry satellite, it orbited directly behind Jason-2 for several weeks so engineers could verify and fine-tune its instruments.
The instruments aboard GOES-16, however, are brand new and more advanced than those aboard previous GOES satellites. So, scientists will use instruments mounted on NASA’s ER-2 high-altitude aircraft, as well as various other instruments closer to Earth—a drone, and a sensor on the International Space Station—to validate the data the GOES-16 satellite is collecting.
