Biogenic volatile organic compounds (BVOCs) are oxidized quickly in the atmosphere to form oxygenated VOC (OVOC) and play crucial roles in the formation of ozone and secondary...

Ambiguity is uncertainty in the prediction of forecast uncertainty, or in the forecast probability of a specific event, associated with random error in an ensemble forecast...

Seven climate models were used to explore the biogeophysical impacts of human-induced land cover change (LCC) at regional and global scales. The imposed LCC led to statistically...

A blending method to merge the NCEP global analysis with the regional analysis from the WRF variational data assimilation system is implemented using a spatial filter for the...

We collected surface snow samples from three different glaciers - Yala, Thana, and Sachin - in the central and western Himalayas to understand the spatial variability and...

This study examines differences in the surface black carbon (BC) aerosol loading between the Bay of Bengal (BoB) and the Arabian Sea (AS) and identifies dominant sources of BC...

We use the extensive set of aircraft and ground-based observations from the NSF/National Center for Atmospheric Research (NCAR) and State of Colorado Front Range Air Pollution...

A coupled magnetosphere ionosphere thermosphere (CMIT 2.0) model has been developed. It is capable of self-consistently calculating global ionospheric electric fields that...

The Gridpoint Statistical Interpolation three-dimensional variational data assimilation (DA) system coupled with the Weather Research and Forecasting/Chemistry (WRF/Chem) model...

This article does not have an abstract or article summary.

The Variable Infiltration Capacity (VIC) model is a macroscale semi-distributed hydrologic model. VIC development began in the early 1990s and the model has since been used...

We discuss and evaluate the representation of atmospheric chemistry in the global Community Atmosphere Model (CAM) version 4, the atmospheric component of the Community Earth...

The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) mission was launched in April 2006. As part of its mission, COSMIC will provide...

The radio occultation (RO) sounding technique that uses signals transmitted by the Global Positioning System (GPS) has evolved as an important global observing technology. In...

Understanding the roles of land surface conditions and atmospheric circulation on continental daily tempera-ture variance is key to improving predictions of temperature...

A novel approach in addressing cyclone global navigation satellite system (CyGNSS) intersatellite and GPS-related calibration issues is proposed, based on a track-wise ﾏバ...

Observations of CO₂ concentration at a mountaintop in the Colorado Rockies in summer show a large diurnal variability with minimum CO₂ concentrations found between 10:00 and...

The primary goal of this study is to derive ice particle terminal velocities from micron to centimeter sizes and for atmospheric pressures covering the range 200–1000 hPa...

The effects of solar wind driving conditions on the polar distribution of large-scale, nondispersive Alfvénic Poynting flux at low altitude during steady magnetosphere...

Observations of long-lived mixed-phase Arctic boundary layer clouds on 7 May 1998 during the First International Satellite Cloud Climatology Project (ISCCP) Regional Experiment...
