Formic (HCOOH) and acetic acids (CH3COOH) are the most abundant carboxylic acids in the Earth's atmosphere and key compounds to aqueous-phase chemistry. Here we present the...

The severity of the double Intertropical Convergence Zone (DI) problem in climate models can be measured by a tropical precipitation asymmetry index (PAI), indicating whether...

Observations of atmospheric carbon monoxide (CO) can only be made on continental and global scales by remote sensing instruments situated in space. One such instrument is the...

Winter storms are disruptive to society and the economy, and they often cause signifi-cant injuries and deaths. Innovations in winter storm forecasting have occurred across the...

The evolution of bubbles in a turbulent oceanic boundary layer is simulated using a multi-size multi-gas bubble model coupled with a Large Eddy Simulation model. Bubbles...

Climate forcing and climate sensitivity are two key factors in understanding Earth's climate. There is considerable interest in decreasing our uncertainty in climate...

This study uses the GRACE (Gravity Recovery And Climate Experiment) and CHAMP(CHAllenging Minisatellite Payload) accelerometer measurements from 2003 to 2008. These measurements...

Global observations of cloud and humidity distributions in the upper troposphere within all geophysical conditions are critically important in order to monitor the present...

Very few frameworks exist that estimate global-scale soil moisture through microwave land data assimilation (DA). Toward this goal, such a framework has been developed by...

The feasibility of using an ensemble Kalman filter (EnKF) to retrieve the wind and temperature fields in an isolated convective storm has been tested by applying the technique...

We present numerical simulations using the Whole Atmosphere Community Climate Model, extended version, constrained below 90km by a combination of NASA's Modern Era Retrospective...

We perform the first multi-model intercomparison of the impact of nudged meteorology on the stratospheric residual circulation using hindcast simulations from the Chemistry-...

Lakes and reservoirs are an integral part of the terrestrial water cycle. In this work, we present the implementation of different water balance models of lakes and reservoirs...

The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In...

The Model for Prediction Across Scales (MPAS) is a novel set of Earth system simulation components and consists of an atmospheric model, an ocean model and a land-ice model. Its...

Ensemble filters are used in many data assimilation applications in geophysics. Basic implementations of ensemble filters are trivial but are susceptible to errors from many...

We use Whole Atmosphere Community Climate Model simulations made under various climate change scenarios to study the evolution of the global-mean temperature trend in the late...

Research on urban vulnerability has grown considerably during recent years, yet consists primarily of case studies based on conflicting theories and paradigms. Assessing urban...

This document describes the multigrid package MUDPACK which includes Fortran subroutines for efficiently approximating the solution to a variety of linear elliptic partial...

Heat and flooding are frequently cited as among the deadliest and costliest climate hazards, respectively, and both are intensifying due to urban developments and climate...
