The potential mechanisms underlying the observed increasing trend in Antarctic summertime sea ice cover for the 1979-2017 period have been investigated using a relatively novel...

Atmospheric chemistry plays a key role in determining the amounts and distributions of oxidants and gaseous precursors that control the formation of secondary gaseous and...

Sudden stratospheric warmings (SSWs) are key to understanding and predicting subseasonal Northern Hemisphere winter climate variability. Here we study the uncertainty in the...

Refractory black carbon (rBC) is a primary aerosol species, produced through incomplete combustion, that absorbs sunlight and contributes to positive radiative forcing. The...

Water vapor in the lower stratosphere exhibits localized maximum values during Northern Hemisphere summer in the Asian and North American (NA) monsoon regions. The processes...

On 24 September 2021, JEDI-MPAS 1.0.0, a new data assimilation (DA) system for the Model Prediction Across Scales - Atmosphere (MPAS-A) built on the software framework of the...

We report observational evidence of cold plasmaspheric electron (< 200 eV) acceleration by ultralow frequency (ULF) waves in the plasmaspheric boundary layer on 10 September...

The observed stratospheric quasi-biennial oscillation (QBO) and the tropospheric Madden-Julian oscillation (MJO) are strongly connected in boreal winter, with stronger MJO...

We measured the carbon isotopic composition (δ(13)C) of ecosystem respiration (δ(13)C(R)) in a subalpine forest across four growing seasons to examine whether patterns in...

We present an observational study of stratospheric gravity wave spectra and seasonal variations of potential energy density at the South Pole (90°S) and Rothera (67.5°S,...

Land models are often used to simulate terrestrial responses to future environmental changes, but these models are not commonly evaluated with data from experimental...

Measurements from passive microwave satellite instruments such as the Advanced Microwave Sounding Unit B (AMSU-B) are sensitive to both liquid and ice cloud particles. Radiative...

This paper describes the implementation of a coarser-resolution physics grid into the Community Atmosphere Model (CAM), containing...

The method developed by the authors referred to in the Preface has been improved in a number of minor respects, to make possible calculations at Taylor numbers up to about 106,...

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth's climate, limiting terrestrial and aquatic food production. Here, we use climate,...

Radiative kernels at the top of the atmosphere are useful for decomposing changes in atmospheric radiative fluxes due to feedbacks from atmosphere and surface temperature, water...

We use simultaneous observations of tropospheric ozone and outgoing longwave radiation (OLR) sensitivity to tropospheric ozone from the Tropospheric Emission Spectrometer (TES)...

Water scarcity is exacerbated by rising water use and climate change, yet state-of-the-art Earth system models typically do not represent human water demand. Here we present an...

GCMs are used by many national weather services to produce seasonal outlooks of atmospheric and oceanic conditions and fluxes. Postprocessing is often a necessary step before...

The Mediterranean region has been identified as a climate hot spot, with models projecting a robust warming and rainfall decline in response to increasing greenhouse gases. The...
