Satellite data reveal widespread changes in Earth's vegetation cover. Regions intensively attended to by humans are mostly greening due to land management. Natural vegetation,...

A 3D growth model is used to simulate pristine ice crystals, which are aggregated using a collection algorithm to create larger, multicrystal particles. The simulated crystals...

Background: Women's status and empowerment influence health, nutrition, and socioeconomic status of women and their children. Despite its benefits, however, research on women's...

This paper argues that a global large eddy simulation can be achieved through the application of the superparametrization (SP) methodology on massively parallel computers. SP...

Results from simulations performed for the Atmospheric Chemistry and Climate Modeling Intercomparison Project (ACCMIP) are analysed to examine how OH and methane lifetime may...

Injection of SO2 into the stratosphere has been proposed as a method to, in part, counteract anthropogenic climate change. So far, most studies investigated injections at the...

This document presents a new global 2? x 2? monthly sea surface temperature (SST) climatology, which was primarily derived from a 1950 to 1979 based SST climatology from the...

Air temperature T a , specific humidity q, CO₂ mole fraction x c , and three-dimensional winds were measured in mountainous terrain from five tall towers within a 1 km region...

The Earth's magnetic field changes in orientation and strength over time. We study the response of the magnetosphere-ionosphere-thermosphere system to a 25% reduction in...

This paper studies the seasonal variation of surface and column CO at three different sites (Paris, Jungfraujoch and Wollongong), with an emphasis on establishing a link between...

To assess a national need for facilities to simulate atmospheric processes, a Colloquium on Atmospheric Simulation was set up to survey current laboratory experimentation on...

The purpose of this document is to describe in detail the code known as the CSM Flux Coupler. This code was developed to serve two specific functions within the NCAR Climate...

This report discusses the Data Base as it is today, assesses CEDAR community utilization of the Data Base and makes recommendations for its future development. Section 2 covers...

To mitigate the projected global warming in the 21st century, it is well-recognized that society needs to cut CO2 emissions and other short-lived warming agents aggressively....

The impacts of black carbon (BC) and particulate matter with aerodynamic diameters less than 2.5 mu m (PM2 : 5) emissions from different source sectors (e.g., transportation,...

Solar prominences are structures of importance because of their role in polar field reversal. We study the long-term variation of the time latitude distribution of solar...

Many methods using ensemble integrations of prediction models as integral parts of data assimilation have appeared in the atmospheric and oceanic literature. In general, these...

Several important developments in the 1960s showed the way to using spectral analysis to identify and describe atmospheric waves predicted by theory. Among these waves were...

Radiative fluxes are critical for understanding the energy budget of the Arctic region, where the climate has been changing rapidly and is projected to continue to change. This...

Lossy compression of climate model output is desperately needed to reduce the massive storage burden on research centers. Lossy compression must be applied carefully to avoid...
