The McIntosh Archive consists of four solar cycles (SC20-23) of synoptic maps of solar features (magnetic polarities, coronal holes, filaments, sunspots, plage) that were...

Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 30 degrees-40 degrees C temperature anomalies across the ice sheet. In Part I,...

Dry deposition (DD) is a major loss process for tropospheric ozone and some reactive nitrogen and carbon precursors. We investigate the response of summertime ozone and its...

The goal of this study is to examine the horizontal scale dependence of vertical eddy flux in the tropical marine surface boundary layer and how this scale dependence of flux...

Methane hydrates, ice-like compounds in which methane is held in crystalline cages formed by water molecules, are widespread in areas of permafrost such as the Arctic and in...

When using the eddy correlation method to measure turbulent scalar fluxes, there is often a spatial separation between the instruments measuring the scalar and the vertical...

This report contains speakers' abstracts as presented at the workshop on Numerical Modeling and Physical Reality held at the Mesa Laboratory of NCAR on September 3-5, 1997 and...

We explore the value of multispectral CO retrievals from NASA/Terra Measurement of Pollution In The Troposphere (MOPITT v5), along with Atmospheric CO₂ Observations from Space...

Organic peroxy radicals (often abbreviated RO₂) play a central role in the chemistry of the Earth's lower atmosphere. Formed in the atmospheric oxidation of essentially every...

We evaluate ozone profile retrievals from the Atmospheric Infrared Sounder (AIRS), the Infrared Atmospheric Sounding Interferometer (IASI), and the Ozone Monitoring Instrument...

The Stratospheric Aerosol and Gas Experiment (SAGE) III has been operating on the International Space Station (ISS) since mid-2017. Nitrogen dioxide (NO2) number density...

Forecasts and observations of thunderstorm motion are key components of severe thunderstorm communication and decision support for preparedness and protective behaviors, as all...

This article presents a case study of large-scale ionospheric convection in the Northern and Southern Hemispheres under strongly northward interplanetary magnetic field (IMF)...

We present results from an analytical model for magnetic buoyancy and rotational instabilities in full spherical shell stellar tachoclines that include rotation, differential...

This paper studies the seasonal variation of surface and column CO at three different sites (Paris, Jungfraujoch and Wollongong), with an emphasis on establishing a link between...

The Arctic is experiencing rapid climate change in response to changes in greenhouse gases, aerosols, and other climate drivers. Emission changes in general, as well as...

A number of studies have used time series of air temperature and specific humidity observations to estimate turbulent heat fluxes. These studies require the specification of...

Background error modeling plays a key role in a variational data assimilation system. The National Meteorological Center (NMC) method has been widely used in variational data...

To better characterize anthropogenic emission-relevant aerosol species, the Gridpoint Statistical Interpolation (GSI) and Weather Research and Forecasting with Chemistry...

The principal objective of this project is to develop an Eulerian regional acid deposition model suitable for assessing source-receptor relationships. The initial task is the...
