Reconstructions of the El Niño-Southern Oscillation (ENSO) are often created using the oxygen isotopic ratio in tropical coral skeletons (δ¹⁸O). However, coral δ¹⁸O can be...

Teleconnections from the Madden–Julian Oscillation (MJO) are a key source of predictability of weather on the extended timescale of about 10–40 d. The MJO teleconnection is...

Dynamical models of organized mesoscale convective systems have identified the important features that help maintain their overarching structure and longevity. The standard...

This paper proposes new diagnostic plots that take advantage of the lack of symmetry in the mean-error distance measure (MED) for binary images to yield a new concept of false...

Airborne measurements of methane (CH₄) and carbon dioxide (CO₂) were taken over the rice growing region of California's Sacramento Valley in the late spring of 2010 and 2011....

In this study, a multi-time-scale four-dimensional variational data assimilation (MTS-4DVar) scheme is developed and applied to the assimilation of radar observations. The...

We highlight a mechanism for the coproduction of research with local communities as a means of elevating the social relevance of the geosciences, increasing the potential for...

Satellite and incoherent scatter radar observations have shown frequently a strong enhancement of upward vertical E x B drifts in the equatorial ionospheric F region near...

The air-sea drag coefficient controls the transfer of momentum from wind to water. In modeling storm surge, this coefficient is a crucial parameter for estimating the surge...

Biological processes in Southern Ocean surface waters have widespread impacts on global productivity and oceanic CO2 storage. Here, we demonstrate that biological calcification...

The Community Land Model (CLM) exhibits biases in evapotranspiration (ET) and total water storage (TWS) in semiarid regions. The TWS seasonal cycle amplitude is too low, while...

A novel additive model analysis of multimodel trends is presented. The approach is motivated by, and particularly suited to, the analysis of multimodel time series of varying...

We compare global-scale changes in satellite estimates of the temperature of the lower troposphere (TLT) with model simulations of forced and unforced TLT changes. While...

A suite of eighteen simulations over the U.S. and Mexico, representing combinations of two mesoscale regional climate models (RCMs), two driving global general circulation...

Recently, two physically based algorithms, the "beta" (β) method and the "constrained-gamma" method, have been proposed for retrieving the governing parameters of the gamma drop...

The ensemble data assimilation version of the Whole Atmosphere Community Climate Model+Data Assimilation Research Testbed developed at National Center for Atmospheric Research...

Observations suggest that processes maintaining subtropical and Arctic stratocumulus differ, due to the different environments in which they occur. For example, specific...

We conducted observational and modeling studies of thermospheric composition and ionospheric total electron content (TEC) variations during two geomagnetically quiet periods...
