Accessing Airborne and Field Campaign Data with the Sub-Orbital Order Tool
Suborbital campaigns serve as a key component of the integrated observing system of the atmosphere by linking satellite observations and surface measurements, as well as probing atmospheric phenomena critical to climate change and air quality issues. These suborbital campaigns often deploy many instruments on different platforms, including aircraft, ships, sondes, …
Full Micro-ArticleACTIVATE Travels to Bermuda
The Aerosol Cloud meTeorology INteractions oVer the western Atlantic Experiment (ACTIVATE) provides much needed knowledge on the relationships between aerosols and clouds. Expanding this knowledge is crucial in understanding the different cloud properties and their resulting impact on climate and weather. Throughout the campaign, two aircraft were deployed: the King …
Full Micro-ArticleAdvancing Aerosol-Cloud-Meteorology Knowledge through ACTIVATE
Despite the crucial role of clouds in maintaining the Earth’s energy balance and water cycle, their formation and evolution processes still have large uncertainties among the international scientific research community. Expanding knowledge on the relationships between aerosols and clouds is key to understanding different cloud properties and their resulting impact …

Full Micro-ArticleA Look into the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES)
- The NASA North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) project was the first NASA Earth Venture – Suborbital mission focused on studying the coupled ocean ecosystem and atmosphere. NAAMES utilizes a combination of ship-based, airborne, autonomous sensor, and remote sensing measurements that directly link ocean ecosystem processes, emissions of …
Exploring the Impact of the 2020 West Coast Wildfires
On September 9, 2020, the fire known as 'The August Complex' became the largest wildfire in California’s history. The fire started as a series of separate fires ignited by lightning strikes. Fueled by periods of drought, record-breaking high temperatures, and drier-than-usual air, the individual fires combined into a single blaze …
Full Micro-ArticleFiring Up Our Understanding of the Atmosphere: A Look into FIREX-AQ
With the occurrence of every annual fire season, fire becomes a more pressing issue as the news in inundated with stories of wildfires raging across the western coast of North America. Though visible smoke from fires dissipates, emissions from the fires can remain in the air longer after fires stop …
Full Micro-ArticleMISR L1 and L2 Product Generation Resumes with New Product Format
The change in Terra orbit altitude in October 2022 required a major update to the generation of MISR L1 and L2 products because the spacecraft orbit tracks are no longer tied to a fixed set of 233 WRS-2 paths. L1 and L2 products from October 14, 2022 (orbit 121388) and …

Full Micro-ArticleObserving Sea-to-Air Aerosol Gas Fluxes Under Extreme Weather Conditions
NAAMES was the first NASA Earth Venture – Suborbital mission focused on studying the coupled ocean ecosystem and atmosphere. NAAMES utilized a combination of ship-based, airborne, autonomous sensor, and remote sensing measurements that directly linked ocean ecosystem processes, emissions of ocean-generated aerosols and precursor gases, and subsequent atmospheric evolution and …
Full Micro-ArticleUnderstanding the North American Monsoon Anticyclone with DCOTSS
Each summer, the North American Monsoon Anticyclone (NAMA) dominates the circulation of the North-Western Hemisphere and acts to partially confine and isolate air from the surrounding atmosphere. Because of NAMA, strong convective storms develop over North America and overshoot the tropopause into the lower stratosphere. These storms carry water and …
