The empirical localization algorithm described here uses the output from an observing system simulation experiment (OSSE) and constructs localization functions that minimize the...

Supercooled liquid water (SLW) and mixed phase clouds containing SLW and ice over the Southern Ocean (SO) are poorly represented in global climate and numerical weather...

Decreases in stratospheric NOx associated with enhanced aerosol have been observed after large volcanic eruptions, for example, after the eruption of Mount Pinatubo in 1991....

Over the eastern United States (EUS), nitrogen oxides (NOx) emission controls have led to improved air quality over the past two decades, but concerns have been raised that...

Ozone pollution transported to the Arctic is a significant concern because of the rapid, enhanced warming in high northern latitudes, which is caused, in part, by short-lived...

Government-administered adulticiding is frequently conducted in response to dengue transmission worldwide. Anecdotal evidence suggests that spraying may create a "false sense of...

Mesoscale forecasts are strongly influenced by physical processes that are either poorly resolved or must be parameterized in numerical models. In part because of errors in...

We provide the first ever characterization of the primary modes of ionospheric Hall and Pedersen conductance variability as empirical orthogonal functions (EOFs). These are...

How and where are coronal loops rooted in the solar lower atmosphere? The details of the magnetic environment and its evolution at the footpoints of coronal loops are crucial to...

Estimates of sources/sinks of carbon dioxide (CO₂) at the Earth's surface are commonly made using atmospheric CO₂ inverse modeling, terrestrial and oceanic biogeochemical...

To improve the initial condition ("analysis") for numerical weather prediction, we attempt to assimilate observations from the Advanced Microwave Sounding Unit-A (AMSU-A) on...

In an effort to prioritize diversity, equity, inclusion, and accessibility (DEIA) in scientific environments, the following guide will help meeting and conference organizers...

Earth system models suggest that anthropogenic climate change will influence marine phytoplankton over the coming century with light-limited regions becoming more productive and...

The 2016 austral spring was characterized by the lowest Southern Hemisphere (SH) sea ice extent seen in the satellite record (1979 to present) and coincided with anomalously...

The NCAR Local Network is an interconnection of all of the computer systems of the SCD and some of the computer systems of other NCAR divisions. It is the function of the...

We integrated soil models with an established ecosystem process model (SIPNET, simplified photosynthesis and evapotranspiration model) to investigate the influence of soil...

This article does not have an abstract or article summary.

The Weather Research and Forecasting Model (WRF) "hybrid" variational-ensemble data assimilation (DA) algorithm was used to initialize WRF model forecasts of three tropical...

Warm season cold cloud-top climatology in the Austral - Indonesian region is examined for evidence of propagating modes of precipitation that originate from elevated heat...

We determine how long a time series must be to estimate covariances and moments up to fourth order with a specified statistical significance. For a given averaging time T there...
