The abundance and sources of ice-nucleating particles, particles required for heterogeneous ice nucleation, are long-standing sources of uncertainty in quantifying aerosol-cloud...

A stratospheric sudden warming episode was self- consistently generated in the coupled National Center for Atmospheric Research Thermosphere, Ionosphere, Mesosphere, and...

The atmospheric concentration of CFC-11 (CCl3F) has declined in response to the phase-out of its production by the Montreal Protocol. Nevertheless, this atmospheric...

Satellite retrievals of tropospheric-column formaldehyde (HCHO) and nitrogen dioxide (NO2) are frequently used to investigate the sensitivity of ozone (O-3) production to...

The accurate prediction of warm-season convective systems and the heavy rainfall and severe weather associated with them remains a challenge for numerical weather prediction...

Improving measurements of water vapour in the upper troposphere and lower stratosphere (UTLS) is a priority for the atmospheric science community. In this work, UTLS water...

Studying the El Nino-Southern Oscillation (ENSO) in the past can help us better understand its dynamics and improve its future projections. However, both paleoclimate...

Report on solutions to the Shallow Water Test Set using the Spectral Transform Method. The solutions in this report were produced by a spectral transform shallow water model,...

Three-hourly present weather reports from ~15000 stations around the globe and from the Comprehensive Ocean-Atmosphere Data Set from 1975 to 1997 were analyzed for diurnal...

This document presents a new global 2? x 2? monthly sea surface temperature (SST) climatology, which was primarily derived from a 1950 to 1979 based SST climatology from the...

An operational multi-model forecasting system for air quality including nine different chemical transport models has been developed and provides daily forecasts of ozone,...

Plant community composition influences carbon, water, and energy fluxes at regional to global scales. Vegetation demographic models (VDMs) allow investigation of the effects of...

Green Bay is the largest freshwater estuarine system on earth, drains one-third of the Lake Michigan basin and delivers one-third of the lake's phosphorus load. Southern Green...

Some of the most intense convective storms on Earth initiate near the Sierras de Cordoba mountain range in Argentina. The goal of the RELAMPAGO field campaign was to observe...

Considerable uncertainties remain in the global pattern of diurnal variation in stratospheric ozone, particularly lower to middle stratospheric ozone, which is the principal...

California droughts are often caused by high-amplitude and persistent ridges near and off the west coast of North America without apparent connections with ENSO. Here with a...

Statistical analysis of extreme values is applied to wind data from National Centers for Environmental Prediction and National Center for Atmospheric Research reanalysis grid...

The budget of column-integrated moist static energy (MSE) is examined in wavenumber-frequency transforms of longitude-time sections over the tropical belt. Cross-spectra with...

Precipitation forecasts from convection-allowing ensembles with 3- and 1-km horizontal grid spacing were evaluated between 15 May and 15 June 2013 over central and eastern...

This paper follows up on the conclusion by Craig and Sneyd (2005) that the solutions to a linearized magnetostatic problem are counterexamples to the magnetostatic model of...
