NASA Rocket Discovers New Energization Process in Upper Atmosphere – NASA Science

Using data from the Twin Rockets to Investigate Cusp Electrodynamics (TRICE-2) rocket launch, NASA scientist Francesca Di Mare and Gregory Howes from the University of Iowa studied waves traveling down Earth’s magnetic field lines into the polar atmosphere. These waves were known to accelerate electrons, which pick up speed as they “surf” along the electric … Read more

As part of ARCSIX, NASA is flying two of its aircraft, with the first flights having occurred on May 28, 2024. The P-3 Orion aircraft from NASA’s Wallops Flight Facility flies at relatively low altitudes to characterize sea ice surface properties, the optical and microphysical properties of cloud and aerosol particles, atmospheric chemistry, radiative fluxes, … Read more

Summary of the Ninth DSCOVR EPIC and NISTAR Science Team Meeting – NASA Science

Kai Yang [UMD] presented the algorithm for retrieving tropospheric O3 from EPIC by estimating the stratosphere–troposphere separation of retrieved O3 profiles. This approach contrasts with the traditional residual method, which relies on the stratospheric O3 fields from independent sources. Validated against the near-coincident O3 sonde measurements, EPIC data biased low by a few DU (up to 5 DU), … Read more

Summary of the 2023 Precipitation Measurement Mission Science Team Meeting – NASA Science

As discussed in Will McCarty’s remarks, AOS is a key component of the Earth System Observatory that was recommended in the 2017 Decadal Survey. The mission will deliver transformative observations fundamental to understanding coupled aerosol– and cloud–precipitation processes that profoundly impact weather, climate, and air quality. Two AOS projects are in the mission concept and … Read more

The year-to-year circulation changes along the coast of the western U.S. can have significant impact on the transport of nutrients that affect fisheries. A 2021 article published in the journal Limnology and Oceanography described a study that used ocean currents derived from satellite altimetry to understand the trajectory of water masses from the southern coast … Read more

The topic of terrestrial water storage variations in California came up in several presentations, focusing on the see-saw swings between very wet and very dry years and the early impacts on groundwater recharge after the record-breaking snow accumulation during the 2022/2023 winter. The process of groundwater recharge – an important objective in the 2017 Earth … Read more
