The role of aqueous multiphase chemistry in the formation of secondary organic aerosol (SOA) remains difficult to quantify. We investigate it here by testing the rapid formation...

Nitrogen is a dominant regulator of vegetation dynamics, net primary production, and terrestrial carbon cycles; however, most ecosystem models use a rather simplistic...

Seasonal predictions of Arctic sea ice conditions often rely on statistical relationships of a set of predictors that have shown skill for historical conditions. However, with...

The skillful prediction of monthly scale rainfall in small regions like Taiwan is one of the challenges of the meteorological scientific community. Taiwan is one of the...

The Community Land Model version 4 (CLM4) overestimates gross primary production (GPP) compared with data-driven estimates and other process models. We use global, spatially...

Previous work has shown that estimates of climate sensitivity vary over time in response to abrupt CO 2 forcing in climate model simulations. The energy fluxes that drive...

Discriminating climate impacts between 1.5 degrees C and 2 degrees C warming levels is particularly important for Central Africa, a vulnerable region where multiple biophysical,...

Thermosphere densities from the CHAMP and GRACE satellites are utilized, for the first time, to study the recovery of the thermosphere as a function of latitude during the...

During boreal summer, convective activity over the eastern Pacific (EPAC) inter-tropical convergence zone (ITCZ) exhibits vigorous intraseasonal variability (ISV). Previous...

A global, 10-yr (February 1997-April 2006), 2-hourly dataset of atmospheric precipitable water (PW) was produced from ground-based global positioning system (GPS) measurements...

The electromagnetic (EM) field variations capable of probing the electrical conductivity of the upper mantle and mantle transition zone have a period range between a few hours...

Much detailed, incremental knowledge being generated by current scientific research on ocean acidification (OA) does not directly address the need of decision makers, who are...

We introduce GUARDIAN, a near-real-time (NRT) ionospheric monitoring software for natural hazards warning. GUARDIAN's ultimate goal is to use NRT total electronic content (TEC)...

Long-lasting Pc5 ultralow frequency (ULF) waves spanning the dayside and extending from L similar to 5.5 into the polar cap region were observed by conjugate ground...

This report depicts the design and preliminary evaluation of an optical flowmeter for measurement of the liquid water content in warm clouds and rain showers. The sensing...

Variability of ice microphysical properties like crystal size and density in cirrus clouds is important for climate through its impact on radiative forcing, but challenging to...

Low-cost sensors have the potential to facilitate the exploration of air quality issues on new temporal and spatial scales. Here we evaluate a low-cost sensor quantification...

This study compares the planetary boundary layer (PBL) height produced by the Goddard Earth Observing System-version 5 (GEOS-5) model with Cloud-Aerosol Lidar and Infrared...

A method for the parameterization of ice-phase microphysics is proposed and used to develop a new bulk microphysics scheme. All ice-phase particles are represented by several...

We present a multiyear time series of column abundances of carbon monoxide (CO), hydrogen cyanide (HCN), and ethane (C2H6) measured using Fourier-transform infrared (FTIR)...
