Changes in observed daily precipitation over the United States between 1950-7...
Changes in observed daily precipitation over the conterminous United States between two 30-yr periods (1950-79 and 1980-2009) are examined using a 60-yr daily precipitation... -
Solar physics from unconventional viewpoints
We explore new opportunities for solar physics that could be realized by future missions providing sustained observations from vantage points away from the Sun-Earth line. These... -
Contribution of ion-induced nucleation to new particle formation: Methodology...
This paper investigates the role of ion-induced nucleation (IIN) in new particle formation events observed near ground level at a sampling site located near Boulder, Colorado... -
The photoelectron‐driven upper hybrid instability as the cause of 150‐km echoes
150 kilometer echoes are strong, coherent echoes observed by equatorial radars looking close to perpendicular to Earth's magnetic field. Observations over a day show a distinct... -
Quantifying the influence of cloud radiative feedbacks on Arctic surface warm...
Understanding the influence of clouds on amplified Arctic surface warming remains an important unsolved research problem. Here, this cloud influence is directly quantified by... -
Seasonal variations of the mesospheric Fe layer at Rothera, Antarctica (67.5°...
Lidar observations of Fe densities between 75 and 105 km above Rothera, Antarctica, are used to characterize the seasonal variations of the mesospheric Fe layer near the... -
Effects of time step size on the simulation of tropical climate in NCAR-CAM3
This paper describes the effects of time step on the simulation of tropical climate in the NCAR-Community Atmosphere Model version 3 (CAM3). A set of multi-year integrations are... -
Projected 21st century decrease in marine productivity: A multi-model analysis
Changes in marine net primary productivity (PP) and export of particulate organic carbon (EP) are projected over the 21st century with four global coupled carbon cycle-climate... -
Predicted impacts of climate and land-use change on surface ozone in the Hous...
This paper studies the effects of climate change under future A1B scenario and land use change on surface ozone (O₃) in the greater Houston, Texas, area. We applied the Weather... -
Evershed and counter-evershed flows in sunspot MHD simulations
There have been a few reports in the literature of counter-Evershed flows observed in well-developed sunspot penumbrae, i.e., flows directed toward the umbra along penumbral... -
Summary Report--Fellowship in Scientific Computing Summer 1972
The 1972 Summer Fellowship Program in Scientific Computing was held at the NCAR Laboratory from June 19 through the end of August. The collection of papers included in this... -
Evaluation of NOAH-MP Land-Model uncertainties over sparsely vegetated sites ...
The water budget and energy exchange over the Tibetan Plateau (TP) region play an important role on the Asian monsoon. However, it is not well presented in the current land... -
Continuous rise of the tropopause in the Northern Hemisphere over 1980–2020
Tropopause height (H) is a sensitive diagnostic for anthropogenic climate change. Previous studies showed increases in H over 1980–2000 but were inconsistent in projecting H... -
Reference upper-air observations for climate: From concept to reality
The three main objectives of the Global Climate Observing System (GCOS) Reference Upper-Air Network (GRUAN) are to provide long-term high-quality climate records of vertical... -
Effects of desiccation stress on adult female longevity in Aedes aegypti and ...
Background: Transmission dynamics of mosquito-borne viruses such as dengue, Zika and chikungunya are affected by the longevity of the adult female mosquito. Environmental... -
Tropospheric ozone assessment report: Tropospheric ozone from 1877 to 2016, o...
From the earliest observations of ozone in the lower atmosphere in the 19th century, both measurement methods and the portion of the globe observed have evolved and changed.... -
Quiet-Sun imaging asymmetries in Na I D₁ compared with other strong Fraunhofe...
Imaging spectroscopy of the solar atmosphere using the Na I D1 line yields marked asymmetry between the blue and red line wings: sampling a quiet-Sun area in the blue wing... -
Hurricane Isabel (2003): New insights into the physics of intense storms. Par...
This study is an observational analysis of the inner-core structure, sea surface temperature, outflow layer, and atmospheric boundary layer of an intense tropical cyclone whose... -
Skillful decadal prediction skill over the Southern Ocean based on GFDL SPEAR...
The Model-Analogs technique is used in the present study to assess the decadal sea surface temperature (SST) prediction skill over the Southern Ocean (SO). The Model-Analogs... -
The strong impact of weak horizontal convergence on continental shallow conve...
Idealized large-eddy simulation (LES) is a basic tool for studying three-dimensional turbulence in the planetary boundary layer. LES is capable of providing benchmark solutions...
