Recent optical observations of aerosols in the upper stratosphere and mesosphere show significant amounts of extinction at altitudes above about 40 km where the stratospheric sulfate aerosol layer ends. Recent modeling of this region reveals that meteoritic smoke settling from the mesosphere and its interaction with the upper part of the sulfate aerosol layer is the origin of the observed extinction. Extinction in this region has major implications for the interpretation and analysis of several… 

Stratospheric SO 2 and sulphate aerosol, model simulations and satellite observations

Abstract. A multiyear study with the atmospheric chemistry general circulation model EMAC with the aerosol module GMXe at high altitude resolution demonstrates that the sulfur gases COS and SO 2 ,

Modeling Stratospheric Aerosols Using a Coupled Aerosol-Chemistry-Climate Model

The presence of the stratospheric aerosol layer, also known as the Junge layer, was first discovered in the early 1960s. This aerosol layer contains mainly binary H2SO4/H2O solution droplets, which

Variability of the Aerosol Content in the Tropical Lower Stratosphere from 2013 to 2019: Evidence of Volcanic Eruption Impacts

This paper quantifies the tropical stratospheric aerosol content as impacted by volcanic events over the 2013–2019 period. We use global model simulations by the Whole Atmosphere Community Climate

Meteoric smoke and H2SO4 aerosols in the upper stratosphere and mesosphere

Meteoric smoke has traditionally been understood as a passive tracer which follows the global mesospheric circulation. Smoke extinction measured by the Solar Occultation For Ice Experiment, however,

Global volcanic aerosol properties derived from emissions, 1990–2014, using CESM1(WACCM)

Accurate representation of global stratospheric aerosols from volcanic and nonvolcanic sulfur emissions is key to understanding the cooling effects and ozone losses that may be linked to volcanic

The contribution of anthropogenic SO2 emissions to the Asian tropopause aerosol layer

Recent observations reveal a seasonally occurring layer of aerosol located from 0° to 100°E, 20° to 45°N and extending vertically from about 13 km to 18 km; this has been termed the Asian tropopause

Recent anthropogenic increases in SO2 from Asia have minimal impact on stratospheric aerosol

Observations suggest that the optical depth of the stratospheric aerosol layer between 20 and 30 km has increased 4–10% per year since 2000, which is significant for Earth's climate. Contributions to

The contribution of anthropogenic SO[subscript 2] emissions to the Asian tropopause aerosol layer

Recent observations reveal a seasonally occurring layer of aerosol located from 0◦ to 100◦E, 20◦ to 45◦N and extending vertically from about 13 km to 18 km; this has been termed the Asian tropopause

Improved tropospheric and stratospheric sulfur cycle in the aerosol-chemistry-climate model SOCOL-AERv2

Abstract. SOCOL-AERv1 was developed as an aerosol-chemistry-climate model to study the stratospheric sulfur cycle and its influence on climate and the ozone layer. It includes a sectional aerosol

Radiative forcing by volcanic eruptions since 1990, calculated with a chemistry-climate model and a new emission inventory based on vertically resolved satellite measurements

Abstract. This paper presents model simulations of stratospheric aerosols with a focus on explosive volcanic eruptions. Using various (occulation and limb based) satellite instruments, with vertical

Long-term, surface-based observations of the stratospheric aerosol layer are presented and compared. These include three LIDAR aerosol backscatter measurements, at Mauna Loa Observatory (Hawaii),

Increase in background stratospheric aerosol observed with lidar at Mauna Loa Observatory and Boulder, Colorado

The stratospheric aerosol layer has been monitored with lidars at Mauna Loa Observatory in Hawaii and Boulder in Colorado since 1975 and 2000, respectively. Following the Pinatubo volcanic eruption

Smoke and Dust Particles of Meteoric Origin in the Mesosphere and Stratosphere

Abstract A height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10−16 g cm−2 s−1 (44 metric tons per day) and the velocity distribution of Southworth and Sekanina,

Dual‐wavelength aerosol lidar backscatter measurements at Mauna Loa Observatory are used to monitor and characterize the 15–30 km stratospheric aerosol layer. The decay of aerosol loading following

Variability in the stratospheric background aerosol over Mauna Loa Observatory

The stratospheric aerosol layer above Mauna Loa Observatory (MLO), Hawaii, has been at low background levels for the past 5 years. This is the first time that an extended non‐volcanic background

The Persistently Variable “Background” Stratospheric Aerosol Layer and Global Climate Change

An increase in the amount of aerosols in the stratosphere during the past decade has decreased the rate of global warming, and climate model projections neglecting these changes would continue to overestimate the radiative forcing and global warming in coming decades.
