The notion that the Atlantic Meridional Overturning Circulation (AMOC) can have more than one stable equilibrium emerged in the 1980s as a powerful hypothesis to explain rapid...

This report describes a research and development program conducted for the National Center for Atmospheric Research by the Minnesota Mining and Manufacturing Company, St. Paul,...

The water solubility of oxidation intermediates of volatile organic compounds that can condense to form secondary organic aerosol (SOA) is largely unconstrained in current...

Tropical forest degradation from logging, fire, and fragmentation not only alters carbon stocks and carbon fluxes, but also impacts physical land surface properties such as...

Measurements of particle formation following the gas phase oxidation of volatile organic compounds (VOCs) emitted by Scots pine (Pinus sylvestris L.) seedlings are reported....

We present airborne observations of gaseous reactive halogen species (HCl, Cl-2, ClNO2, Br-2, BrNO2, and BrCl), sulfur dioxide (SO2), and nonrefractory fine particulate chloride...

The impact of Mexico City (MCMA) emissions is examined by studying its effects on air quality, photochemistry, and on ozone production regimes by combining model products and...

In autumn deep convection in the Mediterranean region is a common phenomenon. The local events characterized by deep convection are still a difficult task even for high...

The variability of zonally resolved tropical energy budgets in association with El Niño-Southern Oscillation (ENSO) is investigated. The most recent global atmospheric...

Atmospheric rivers (ARs) are intensive poleward moisture transport events that are essential to the global hydrological cycle and are often linked to extreme weather events. We...

The newly developed fast Earth system model CLIMBER-X is presented. The climate component of CLIMBER-X consists of a 2.5-D semi-empirical statistical- dynamical atmosphere...

Spatial variability in the exchange of energy and moisture is a key control on numerous atmospheric, hydrologic, and environmental processes. Using observations made on fair...

The low-resolution version of the Community Climate System Model, version 4 (CCSM4) is a computationally efficient alternative to the intermediate and standard resolution...

Citizen science promotes public participation in the discovery of new knowledge. Also known as volunteer monitoring or crowd sourcing, this form of public science has taken hold...

Many problems in the environmental and biological sciences involve the analysis of large quantities of data. Further, the data in these problems are often subject to various...

An unusually long data set was acquired at the sodium lidar facility at Colorado State University ( 41N, 105W), between Sep 18 and Oct 01, 2003, including a 9-day continuous...

We present observational evidence for the presence of MHD (magnetohydrodynamic) waves in the solar photosphere deduced from SOHO/MDI(Solar and Heliospheric Observatory/Michelson...

This work presents a method for estimating the migrating diurnal tide (DW1) component of mesospheric H2O from observations of the temperature tide and zonal-mean H2O made by the...

The measurement of OH reactivity, the inverse of the OH lifetime, provides a powerful tool to investigate atmospheric photochemistry. A new airborne OH reactivity instrument was...

During Biogenic Aerosols--Effects on Clouds and Climate (BAECC), the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Program deployed the Second ARM Mobile...
