In recent years, the mesosphere (50 to 85-100 km) has evoked great scientific interest as long-term changes due to global warming can be clearly captured due to the large...

A dense forest of slender bright fibrils near a small solar active region is seen in high-quality narrowband Ca II H images from the SuFI instrument onboard the SUNRISE balloon-...

Dry deposition velocities (V-d) for peroxyacetyl nitrate (PAN) calculated using two community dry deposition models with different treatments of both stomatal and nonstomatal...

An oxidation flow reactor (OFR) is a vessel inside which the concentration of a chosen oxidant can be increased for the purpose of studying SOA formation and aging by that...

While internal climate variability is known to affect climate projections, its influence is often underappreciated and confused with model error. Why? In general, modeling...

Stratocumulus clouds over the Southern Ocean have fewer droplets and are more likely to exist in the predominately supercooled phase than clouds at similar temperatures over...

This study reviews the progress made in modeling precipitations in four generations of reanalyses from the European Center for Medium‐Range Weather Forecasts, using...

The semiannual oscillation (SAO) is a twice-yearly northward movement (in May-June-July (MJJ) and November-December-January (NDJ)) of the circumpolar trough of sea level...

The joint Taiwan-United States FORMOSAT-3/COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate) mission, hereafter called COSMIC, is the first...

Oxidation of biogenic volatile organic compounds (BVOC) by the nitrate radical (NO3) represents one of the important interactions between anthropogenic emissions related to...

In situ observations of reduced stratospheric water vapor combined with those of ice particle formation are rarely conducted. On the one hand, they are essential to broaden our...

In this study, the canopy effects on the vertical ozone exchange within and above Californian orchard are investigated. We examined the comprehensive dataset obtained from the...

This paper develops a multivariate mosaic subgrid approach to represent subgrid variability in land surface models (LSMs). The k-means clustering is used to take an arbitrary...

We examine characteristics of the seasonal variation of thermospheric composition using column number density ratio n-ary sumation O/N-2 observed by the NASA Global Observations...

This study employs a fully coupled meteorology-chemistry-snow model to investigate the impacts of light-absorbing particles (LAPs) on snow darkening in the Sierra Nevada. After...

The Van Allen Probes spacecraft have provided detailed observations of the energetic particles and fields environment for coronal mass ejection (CME)-shock-driven storms in 2012...

Two cases of observed widespread moderate-or-greater (MOG) clear-air turbulence (CAT) in different synoptic patterns are investigated using a nested high-resolution NWP model....

For the first time, vertical column measurements of nitric acid (HNO₂) above Eureka (80.1°N, 86.4°W), Canada, have been made during polar night using lunar spectra recorded...

Long-range transport of biogenic emissions from the coast of Antarctica, precipitation scavenging, and cloud processing are the main processes that influence the observed...

We used SCIAMACHY (10:00 LT) and OMI (13:30 LT) tropospheric NO₂ columns to study diurnal and seasonal patterns in NO₂ concentrations over India. Using characteristics of...
