National Oceanic and Atmospheric Administration

• 1. Introduction

  ›

  The National Oceanic and Atmospheric Administration issues more than 734,000 weather forecasts and 850,000 river forecasts every single year. It tracks hurricanes as they form over warm Atlantic water, monitors the ozone layer from orbit, and counts the fish in America's coastal seas. And yet, for most of its existence, NOAA has never been established in law. An agency this central to American life was created by an executive order in 1970 and, decades later, still operates without formal congressional authorization.

  That legal gap became a real vulnerability in the 2020s, when proposals to slash the agency's research division put its future in question. How did such a sprawling scientific institution come into being? What does it actually do, and who runs it? And what happens when the science it produces collides with political pressure?

• 2. Deep Roots

  ›

  The U.S. Survey of the Coast, one of NOAA's oldest ancestors, was founded in 1807, making it one of the earliest federal agencies ever created. The Weather Bureau followed in 1870, and the Bureau of Commercial Fisheries in 1871. By 1917, the Coast and Geodetic Survey Corps had taken form as well. These institutions spent more than a century accumulating expertise, ships, and equipment before they were ever unified under one roof.

  The immediate predecessor to NOAA was the Environmental Science Services Administration, known as ESSA, which absorbed the Coast and Geodetic Survey, the Weather Bureau, and the uniformed Corps in 1965. ESSA lasted only five years before it too was folded into something larger.

  President Richard Nixon proposed the new agency in 1970 with a specific vision: he wanted better protection from natural hazards, a fuller understanding of the total environment, and what he called "exploration and development leading to the intelligent use of our marine resources." But where to house this new body inside the federal government became an unexpected problem.

  NOAA landed in the Department of Commerce rather than the Department of Interior, and the reason was entirely personal. Nixon was furious at his interior secretary, Wally Hickel, who had written a letter urging Nixon to listen to Vietnam War demonstrators. Nixon punished Hickel by keeping NOAA out of his department. A letter about a war protest shaped the bureaucratic home of the nation's weather and ocean agency.

• 3. A Flag and Its History

  ›

  Ships of the old Coast and Geodetic Survey flew a distinctive flag, authorized in 1899, that carried a red triangle centered inside a white circle on a blue field. The triangle symbolized triangulation, the geometric method surveyors used to measure the land. That flag flew until 1970.

  When NOAA absorbed the Survey's ships and personnel, it adapted the design rather than inventing a new one. The NOAA flag kept the blue field, the white circle, and the red triangle, but placed the NOAA logo at the center of the triangle: a circle divided by the silhouette of a seabird into a dark upper section and a lighter lower section.

  NOAA ships today fly the same ensign as U.S. Navy vessels, but the NOAA flag serves as a distinguishing mark so they are not confused for Navy ships. On single-masted vessels, the flag flies just beneath the ship's commissioning pennant; on multi-masted ships it goes at the head of the forwardmost mast.

• 4. The Science Network

  ›

  NOAA's research arm, the Office of Oceanic and Atmospheric Research, studies phenomena as varied as tornadoes, El Nino and La Nina events, deep-sea thermal vents, and the transport of air pollutants across continents. The research network includes seven internal laboratories, 30 Sea Grant university programs, six undersea research centers, and 13 cooperative institutes with academic partners.

  One of those labs, the Atlantic Oceanographic and Meteorological Laboratory, sits on Virginia Key in Miami, Florida. Its scientists work on hurricanes, coastal ecosystems, ocean chemistry, and global carbon systems in partnership with the University of Miami's Rosenstiel School of Marine and Atmospheric Science through a joint enterprise called the Cooperative Institute for Marine and Atmospheric Studies.

  In 1977, the Pacific Marine Environmental Laboratory deployed the first successful moored equatorial current meter, an instrument that became the foundation of the Tropical Atmosphere Ocean array. That effort fed into the Tropical Ocean-Global Atmosphere program, which began in 1984.

  The Air Resources Laboratory focuses on a narrower but crucial problem: tracking how pollutants move through the atmosphere. Its specific goal is to improve prediction of air quality, dispersion of pollutant plumes, and atmospheric deposition. The work is less dramatic than hurricane tracking but shapes the air quality forecasts millions of people check every day.

  Every year, NOAA also publishes the Arctic Report Card, an annual accounting of how changing conditions affect the Arctic environment and the communities that live there. In 2019, the report was compiled by 81 scientists from 12 nations.

• 5. Satellites and the Sky

  ›

  NOAA's National Environmental Satellite, Data, and Information Service traces its satellite lineage back to TIROS-1, NASA's first geostationary satellite, launched in 1960. NESDIS has managed polar-orbiting satellites since 1966 and geosynchronous satellites since 1974. NOAA's first polar-orbiting environmental satellite of its own launched in 1979.

  In 1983, NOAA assumed operational responsibility for the Landsat satellite system. Since May 1998, NESDIS has also operated the Defense Meteorological Satellite Program satellites on behalf of the Air Force Weather Agency.

  The current generation of geostationary satellites, the GOES-R series, launched in November 2016. These satellites are the eyes that track severe storms developing over the continental United States and adjacent ocean regions.

  The data those satellites collect does not stay with NOAA alone. NESDIS's National Centers for Environmental Information archives weather and climate records gathered not just by NOAA, but also by the U.S. Navy, the U.S. Air Force, the Federal Aviation Administration, and meteorological services from around the world. That archive is one of the most extensive collections of atmospheric and oceanic data in existence.

• 6. The Sharpwater Moment

  ›

  In September 2019, Hurricane Dorian bore down on the southeastern United States after devastating the northwestern Bahamas. By the 1st of September, NOAA had already issued a statement making clear that the storm's forecast path did not include Alabama. That same day, President Donald Trump posted that Alabama, among other states, would most likely be hit harder than anticipated.

  The Birmingham, Alabama office of the National Weather Service responded almost immediately, posting that Alabama would not see any impacts from Dorian. The correction was accurate. But on the 6th of September, NOAA published a statement from an unnamed spokesperson that backed Trump's original claim and labelled the Birmingham office's correction as wrong.

  According to reporting by The New York Times, that statement was issued after Commerce Secretary Wilbur Ross threatened to fire high-level NOAA staff unless they fell in line. The Department of Commerce called that account false.

  The Washington Post separately reported that NOAA had twice ordered National Weather Service employees not to offer any opinion on Dorian and to stick only to official National Hurricane Center forecasts. The first order followed Trump's September 1st comments. The second came on the 4th of September, after Trump displayed a weather map that had been altered with a black marker to show Dorian possibly reaching Alabama.

  On the 9th of September, the director of the National Weather Service addressed staff at an Alabama NWS meeting and said the Birmingham team had stopped public panic and ensured public safety. He noted the office had not known the incoming calls were triggered by the president's tweet when it issued its clarification. The agency's acting chief scientist meanwhile said he was pursuing potential violations of NOAA's scientific integrity policy.

• 7. The Workforce and Its Fractures

  ›

  As of 2021, NOAA employed 11,833 civilian workers. Another 321 uniformed service members formed the NOAA Commissioned Officer Corps, a branch of uniformed personnel who crew the agency's ships and aircraft and fill scientific and administrative roles. The Corps is led by a two-star Rear Admiral.

  In January 2023, Congressman Frank Lucas, newly appointed chair of the House Science, Space and Technology Committee, released draft legislation to give NOAA an independent legal footing for the first time in its history. His reasoning was blunt. Republican leaders had signaled they did not want to fund programs that had not been formally reauthorized by Congress. "NOAA is very important, so we need to get it authorized," Lucas said.

  Two years later, the agency faced a sharper disruption. On the 27th of February 2025, staffers from the Department of Government Efficiency entered NOAA's headquarters and several hundred employees, mainly those on probationary status, were laid off. By early March, the total number of departures had reached roughly 1,300 staff members, or about 10% of the total workforce.

  In June 2025, the Department of Defense announced it would no longer supply critical weather data to scientists and forecasters, including those at NOAA. The withdrawal of that data marked a new pressure point for an agency that had spent more than two centuries building the most comprehensive picture of American weather and seas ever assembled.
