NSF NCAR GV Aces

Eclipse Observations with the Airborne Coronal Emission Surveyor (ACES)  

The Airborne Coronal Emission Surveyor (ACES) is a new instrument using the Airborne Stabilized Platform for Infrared Experiments (ASPIRE) to explore the large-scale coronal IR emission spectrum during the 2024 total solar eclipse. ACES and ASPIRE will fly on the NSF NCAR Gulfstream V along the path of totality during the second Great American Eclipse in 2024. ACES will use the 20 cm optical feed from ASPIRE to map emission line intensity as a function of radius and solar magnetic structure.

Cold Air Outbreak Experiment in the Sub-Arctic Region (CAESAR)

One of Earth's most intense air mass transformations happens when cold Arctic air flows out over the much warmer open oceans in so-called Cold-Air Outbreaks (CAOs). The surface heat fluxes are among the highest observed on Earth, supporting highly convective clouds capable of producing heavy snowfall and occasionally spawning intense "polar lows." Surprisingly little is known about their Lagrangian evolution, the relationship between up- and downstream conditions, and between the surface fluxes, boundary-layer structure, cloud and precipitation properties, and mesoscale circulations. These clouds provide a powerful modeling test bed for improving the representation of mixed-phase cloud processes in large eddy simulations, numerical weather prediction, and global climate models.

NSF Facility and Instrumentation Request Process (FIRP)

A revised version of the Facility and Instrumentation Request Process (FIRP) solicitation was published by NSF on 3 July 2023.  The solicitation describes the mechanism by which the research community can propose projects that require access to facilities and instrumentation sponsored by the Facilities for Atmospheric Research and Education (FARE) Program in the Division of Atmospheric and Geospace Sciences (AGS).  Specialized FARE instrumentation and facilities include the Lower Atmosphere Observing Facilities (LAOF) and the Community Instruments and Facilities (CIF).  For more information, please contact Dr. Shree Mishra, NSF FARE Program Director  (sumishra@nsf.gov).

The Mystery of Missing Water From Mountain Sources

On the westward side of the Rocky Mountains, the Upper Colorado River Basin has historically been a wintertime storage bin for snowpack. As the snowpack melts, the resulting runoff joins water sources from other mountain watersheds and fills the coffers of streams and rivers fanning out into the Western United States.

EOL Scientist Spotlight: Hunga Tonga-Hunga Ha’apai Volcano Eruption Plume Study

Dr. Holger Vömel, a Senior Scientist in EOL’s In-situ Sensing Facility, has a publication in Science, on his study of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano. 

How monsoon winds impact climate change by transporting pollutants into the upper atmosphere

While the Asian monsoon brings rain that is vital for the agricultural economy of the vast region, it is also known to suck up into the upper atmosphere chemical pollutants that accelerate climate change.
