On Nov 20, the NSF NCAR High Altitude Observatory (HAO) celebrated 85 years (you read that right: 85 years!!!) of studying the Sun! Founded in 1940 and then merged with NCAR in 1962, HAO has conducted world-class research, pioneering coronagraph development, eclipse expeditions & more!

Let’s explore the NSF NCAR Timeline! In 1961, NCAR found its forever home in Boulder, CO, on Table Mesa. After a vote by Boulder residents in favor of the site, the land on Table Mesa was donated to the NSF by the State of Colorado.

Hurricane Melissa produced the fastest hurricane winds to be recorded by a dropsonde, verified by reviewing data at NSF NCAR! Hurricane Melissa’s 252 mph wind gust surpassed the previous record from Typhoon Megi over the Western Pacific in 2010, where a dropsonde measured wind gusts of 248 mph.

The team aimed not only to get a better picture of the air in and around NYC– where ocean, city, and forests converge– but also how pollution ebbs and flows in 24 hours. NSF NCAR pilots would fly the plane, a “flying lab” with research equipment, at both high and low altitudes to collect data.
