Aerosol and Cloud Studies From CALIPSO and the A-Train
Atmospheric aerosols and clouds are important elements of the climate system, significantly affecting the radiation budget and playing important roles in the hydrologic cycle and atmospheric chemistry.
The CALIPSO satellite carries an ...
Arctic Transitions in the Land-Atmosphere System (ATLAS)
This section includes papers describing how the land surface in the Arctic respond to climate variability and influence the climate system. Results from the NSF-sponsored Arctic Transitions in the Land Atmosphere System (ATLAS) Project are ...
CalNex: Research at the Nexus of Air Quality and Climate Change
The California Air Resources Board and the National Oceanic and Atmospheric Administration conducted a joint field study of atmospheric processes over California and the eastern Pacific coastal region in 2010. CalNex, a collaborative, ...
Characterization of Asian Aerosols and Their Radiative Impacts on Climate
ACE-Asia was an international aerosol characterization experiment designed to quantify the radiative impact of Asian aerosol on climate. It involved more than 100 groups from 13 countries, three aircraft, two ships, and numerous surface ...
Climate and Weather of the Sun-Earth System (CAWSES)
A few years ago SCOSTEP initiated a new international scientific program called CAWSES (`Climate and Weather of the Sun‐Earth System') which aims at a better understanding of the Sun-Earth system including solar terrestrial influences on ...
Coupling Between the Lower and Upper Atmosphere
The Earth's ionosphere, embedded within the thermosphere, is a complex environment influenced by solar and magnetospheric processes from above, and upward propagating disturbances from below. At lower altitudes, the troposphere, ...
[D-F]
The CLOUDYCOLUMN project during the Second Aerosol Characterization Experiment (ACE2) was focused on the impact of anthropogenic aerosol on cloud radiative properties, the so-called aerosol indirect effect on climate. For the first time, ...
First Results From the RADAGAST Experiment
The RADAGAST (Radiative Atmospheric Divergence using ARM Mobile Facility, GERB data and AMMA STations) experiment took place in Niamey, Niger, in 2006, within the African Monsoon Multidisciplinary Analysis project. RADAGAST coordinated ...
[G-K]
Atmospheric aerosols play a dual role in the climate system and the hydrologic cycle. By scattering sunlight and reflecting a fraction of it back to space, aerosols cool the climate system; by absorbing sunlight, aerosols further cool the ...
Global Dimming and Brightening
Recent evidence suggests that solar radiation reaching the
Earth's surface has not been constant over time but has undergone substantial variations on decadal timescales. The available observations suggest a widespread decrease in surface ...
ILAS-II: The Improved Limb Atmospheric Spectrometer II
The Improved Limb Atmospheric Spectrometer (ILAS) is the satellite-borne sensor for stratospheric ozone layer observations on the basis of solar occultation technique, which was operated in 1996/1997 over high latitude regions of both ...
The circumpolar flaw lead is a perennial characteristic of the central Arctic. The International Polar Year (IPY) Circumpolar Flaw Lead Experiment (CFL) included a 10-month ship-based experiment that
examined the relationship of climate ...
Intercontinental Chemical Transport Experiment-North America (INTEX-A/ICARTT)
Intercontinental Chemical Transport Experiment is an ongoing two-phase integrated atmospheric field experiment being performed over North America (http://cloud1.arc.nasa.gov/intex-na/). Its first phase (INTEX-A) was performed in the summer ...
During April and May of 2002, two coordinated atmospheric chemistry field studies were conducted on opposite sides of the North Pacific: PEACE-B was organized by Japanese scientists over the western Pacific and ITCT-2K2 was organized by ...
International Consortium for Atmospheric Research on Transport and Transformation (ICARTT): North America to Europe
In the summer of 2004 several separate field programs intensively studied the photochemical, heterogeneous chemical and ...

Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA)
The Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) was designed to create the new knowledge needed to understand the climatological, ecological, biogeochemical, and hydrological functioning of Amazonia, the impact of land use ...
Modeling of Chemistry and Climate (MC2)
The stratospheric modeling community has recently collaborated in a major model intercomparison exercise as a contribution to the Stratospheric Processes and their Role in Climate (SPARC) program CCMVal (Chemistry Climate Model Validation) ...
This theme is based on the measurements and theoretical investigations that comprised the NASA-sponsored experiment, “Transport and Chemical Evolution over the Pacific (TRACE-P),” that was conducted by the NASA Global Tropospheric ...
Observations, Estimation, and Prediction of Precipitation at all Scales
New observing and modeling capabilities prompt unprecedented opportunities for progress in precipitation research. Pivotal among these are the installation of science-grade hydrometeorological networts in mountainous regions, undertaking of ...
Pacific Exploratory Mission in the Tropics - B (PEMTROPICS-B) Part 2
This special section is based on the measurements and theoretical investigations that comprised the NASA-sponsored experiment, “Pacific Exploratory Mission in the Tropics-B (PEM TROPICS-B),” that was conducted by the NASA Global ...
This special section provides a subset of papers presented at the 2003AAAR International Specialty Conference entitled “Particulate Matter: Atmospheric Science, Exposure, and the Fourth Colloquium on PM and Health.” One of the meeting's ...
