An ensemble-based tangent linear model (TLM) is described and tested in data assimilation experiments using a global shallow-water model (SWM). A hybrid variational data...

This paper examines the impacts of technology (e.g., Chromebooks, Google Drive) on teacher learning and student activity in the development and implementation of a deeply...

The International GNSS Service (IGS) diurnal ROTI maps ionospheric product was developed to characterize ionospheric irregularities occurrence over the Northern hemisphere and...

This study uses data from a survey of coastal Miami-Dade County, Florida, residents to explore how different types of forecast and warning messages influence evacuation...

A climatology of cold air outbreaks (CAOs) over North America is presented on the basis of a 50 year simulation of the Whole Atmosphere Community Climate Model (WACCM). This...

Observed tidal geomagnetic field variations are due to a combination of electric currents in the ionosphere, ocean, and their induced counterparts. Using these variations to...

The Southern Ocean has warmed substantially, and up to early 21st century, Antarctic stratospheric ozone depletion and increasing atmospheric CO2 have conspired to intensify...

Ground-based Fourier transform infrared (FTIR) measurements of solar absorption spectra can provide ozone total columns with a precision of 2% but also independent partial...

Temperature profiles in polar latitudes during summer reveal a strong and persistent inversion layer associated with the polar summer tropopause. This inversion layer is...

We here present, document and validate a new atmospheric component of the Community Earth System Model (CESM1): the Specified Chemistry Whole Atmosphere Community Climate Model...

This paper presents the design of a 449 MHz radar for wind profiling, with a focus on modularity and solid-state transmitter design. It is one of the first wind profiler radars...

The Community Land Model version 4 overestimates gross primary production (GPP) compared with estimates from FLUXNET eddy covariance towers. The revised model of Bonan et al....

This is a report on Omega wind error estimation. To make this a single source document on Omega windfinding and its errors, the authors have included derivation of basic...

Numerous components of the Arctic freshwater system (atmosphere, ocean, cryosphere, and terrestrial hydrology) have experienced large changes over the past few decades, and...

Regional climate change impacts show a wide range of variations under different levels of global warming. Watersheds in the northeastern region of the United States (NEUS) are...

This article does not have an abstract or article summary.

The Climate Project at the National Center for Atmospheric Research held a symposium on analysis and modeling of climate on large spatial scales from 29 November to 2 December...

Satellite observations of carbon dioxide (CO₂) offer novel and distinctive opportunities for improving our quantitative understanding of the carbon cycle. Prospective...

We use seeing-free high spatial resolution Ca II H data obtained by the SUNRISE observatory to determine properties of slender fibrils in the lower solar chromosphere. In this...

With today's increasing attention to open science and open data, knowledge production and data production have significant impacts on both research and policy arenas. We...
