This report presents absorption cross sections at temperatures of 293, 273, 253, 233, 213 and 203 K for the chlorofluorocarbon species CFC-11 (CC13F), CFC-12 (CC12F2), CFC-13...

Potential future changes in the genesis frequency and distribution of tropical cyclones are important for society, yet uncertain. Confidence in the model projections largely...

A nascent in situ cirrus was observed on January 11, 2019 in the tropical tropopause layer (TTL) over the southwestern Indian Ocean, with the use of balloon-borne instruments....

This study presents an analytical model for the amplitude of lee waves on the boundary-layer inversion in two-dimensional flow. Previous linear lee wave models, in which the...

The International Monitor for Auroral Geomagnetic Effects network magnetic measurements during the period 1995-2009 are used to characterize the annual variations in the...

In a recent study, the authors performed numerical simulations of moist nearly neutral flows over a ridge using the Weather Research and Forecasting (WRF) Model in a regime...

Paleoclimate model simulations provide reference data to help interpret the geological record and offer a unique opportunity to evaluate the performance of current models under...

Nitric oxide (NO) is emitted in large quantities from coal-burning power plants. During the day, the plumes from these sources are efficiently mixed into the boundary layer,...

Conversations with Bernhard Haurwitz.

Two high-precision CEDAR instruments, an OH Mesospheric Temperature Mapper (MTM) and a Na Temperature Lidar, have been used to investigate seasonal variability in the mid-...

We use observations of N₂O and mean age to identify realistic transport in models in order to explain their ozone predictions. The results are applied to 15 chemistry climate...

Tropical cyclone (TC) low-level tangential wind structure is known to be an important input for risk assessment (e.g., storm surge). However, a realistic TC wind structure model...

Combining new constraints on future socio-economic trajectories and the climate system's response to emissions can substantially reduce the projection uncertainty currently...

The influence of cloud radiative feedback, remote ENSO heat flux forcing, and oceanic entrainment on persisting North Pacific sea surface temperature (SST) anomalies is...

Thailand experiences severe air quality issues, predominantly due to PM2.5 pollution that surpasses WHO guidelines. The main sources are attributed to energy production,...

In this paper, we examine the mode of dynamo action in the implicit large-eddy magnetohydrodynamical simulation of solar convection reported upon in Ghizaru et al. Motivated by...

Isoprene, a volatile organic compound that is mainly emitted from trees, rapidly reacts with hydroxyl radical (OH) during daytime and subsequently forms ozone and aerosols in...

Gravity waves (GWs) strongly affect atmospheric dynamics and photochemistry and the coupling between the troposphere, stratosphere, mesosphere, and thermosphere. In addition,...

In this two-part paper, a description is provided of a version of the AM4.0/LM4.0 atmosphere/land model that will serve as a base for a new set of climate and Earth system...

We report on measurements of acyl peroxy nitrates (APNs) obtained from two ground sites and the NSF/National Center for Atmospheric Research C-130 aircraft during the 2014 Front...
