Radionuclide Data from GEOTRACES Improve Particle Flux Estimates
New measurements of multiple radionuclides in the Atlantic Ocean offer a robust constraint on the sinking flux of particles and associated vertical fluxes of biogeochemically important elements.
Jupiter’s Stressed Out Magnetosphere Causes Aurora and Heating
Force imbalance between Jupiter’s ionosphere and magnetosphere leads to wave generation to release this stress, but the waves also accelerate particles, causing aurora and heating.
A Comprehensive Estimate on the Entropy Budget in the Ocean
An analysis of the energy budget in the ocean estimates the Carnot work to be 110 terawatts and the ocean’s Carnot efficiency to be 0.86%.
First Multi-Decade Simulation of the Earth’s Radiation Belt
A new simulation of the Earth’s electron radiation belts captures large-scale variations over nearly three solar cycles, and replicates primary cyclical features and extreme behaviors.
Fiber Optics Opens Window into Subsurface Deformation
The distributed deformation of buried materials is difficult to map, but a new approach is able to resolve vertical deformation over the length of a fiber optic cable.
High Resolution Imaging of Ionosphere by Lightning
The three-dimensional distribution of electron density in the Earth’s ionosphere could be obtained using the broadband radiation of naturally occurring lightning discharges.
Measuring the Magnetic Reconnection Rate in the Magnetotail
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.
Improving Retrievals for Partially Cloudy Pixels
Cloud retrievals for partly cloudy pixels might be able to be improved by using high-resolution samples in a visible to near-infrared band, which many satellite sensors offer.
The ILAMB System for Benchmarking Land Surface Models
An evolving set of tools helps land surface model developers optimize the realism of their parameterizations for the next generation of weather and climate models.
