The influence of climate feedbacks on regional hydrological changes under global warming
The influence of climate feedbacks on regional hydrological changes under warming is poorly understood. Here, a moist energy balance model (MEBM) with a Hadley Cell parameterizati…
Comparing gravity waves in a kilometre-scale run of the IFS to AIRS satellite observations and ERA5
Atmospheric gravity waves (GWs) impact the circulation and variability of the atmosphere. Sub-grid scale GWs, which are too small to be resolved, are parameterized in weather and …
On Generalized Additive Models for Representation of Solar EUV Irradiance
In the context of space weather forecasting, solar EUV irradiance specification is needed on multiple time scales, with associated uncertainty quantification for determining the a…
Coupled Geodynamical-Geochemical Perspectives on the Generation and Composition of Mid-Ocean Ridge Basalts
Owing to their abundance and relative availability on Earth’s seafloor, mid-ocean ridge basalts (MORBs) have a well-defined chemical element budget, reflected by the low standard …
Machine learning-based emulator for the physics-based simulation of auroral current system
Using a machine learning technique called echo state network (ESN), we have developed an emulator to model the physics-based global magnetohydrodynamic (MHD) simulation results of…
A NASA GISTEMPv4 Observational Uncertainty Ensemble
The historical global temperature record is an essential data product for quantifying the variability and change of the Earth system. In recent years, better characterization of o…
Why are Mountaintops Cold? The Transition of Surface Lapse Rate on Dry Planets
Understanding surface temperature is important for habitability. Recent work on Mars has found that the dependence of surface temperature on elevation (surface lapse rate) converg…
The Hunt for Perpendicular Magnetic Field Measurements in Plasma
We are reporting the discovery of a new radio analysis for studying plasma magnetic fields. In the high frequency regime, wherein the electromagnetic wave frequency exceeds the pl…
Long-term trends in the distribution of ocean chlorophyll
The concentration of chlorophyll-a (CHL) is an important proxy for autotrophic biomass and primary production in the ocean. Quantifying trends and variability in CHL are essential…
Global analysis of surface ocean CO2 fugacity and air-sea fluxes with low latency
The Surface Ocean CO2 Atlas (SOCAT) of CO2 fugacity (fCO2) observations is a key resource supporting annual assessments of CO2 uptake by the ocean and its side effects on the mari…
Physical modeling of gelatinous zooplankton sinking in the deep global ocean
Decaying gelatinous zooplankton (GZ) originating from surface waters has been proposed as a possible major contributor to the biological carbon pump. However, studies arrived at l…
Comment on calibration, validation, and evaluation of WEPP with natural runoff plot data
15 16 Wang et al (2022) undertook an evaluation of the Water Erosion Prediction Project (WEPP) 17 model on 134 USLE runoff and soil loss plots. Wang et al did not compare the capa…
A grey area of research ethics: Public vs private spaces for internet-based research
Internet-based researchers (IBR) are often presented with the challenge of determining what is in the public and private domain for online ethics. Convery and Cox (2012) argue tha…
Ensemble-Based Data Assimilation of Significant Wave Height from Sofar Spotters and Satellite Altimeters with a Global …
An ensemble-based method for wave data assimilation is implemented using significant wave height observations from the globally distributed network of Sofar Spotter buoys and sate…

Anatomy of the tsunami and Lamb waves-induced ionospheric signatures generated by the 2022 Hunga Tonga volcanic eruptio…
As tsunamis propagate across open oceans, they remain largely unseen due to the lack of adequate sensors, hence limiting the scope of existing tsunami warnings. A potential altern…
Non-tidal oceanographic fluctuation characteristics recorded in DONET ocean-bottom pressure time series using principal…
Ocean bottom pressure-gauge (OBP) records play an important role in seafloor geodesy, but oceanographic fluctuations in OBP data are a major source of noise in seafloor transient …
Convective self-compression of cratons and the stabilization of old lithosphere
