Foodborne diseases have large economic and societal impacts worldwide. To evaluate how the risks of foodborne diseases might change in response to climate change, credible and...

Ionospheric day-to-day variability is a ubiquitous feature, even in the absence of appreciable geomagnetic activities. Although meteorological perturbations have been recognized...

We report observations of small-scale swirls seen in the solar chromosphere. They are typically 2 Mm in diameter and last around 10 minutes. Using spectropolarimetric...

Responses of the thermohaline circulation (THC) to freshwater forcing (hosing) in the subpolar North Atlantic Ocean under present-day and the last glacial maximum (LGM)...

The National Center for Atmospheric Research (NCAR) led a partnership to advance the state-of-the-science of solar power forecasting by designing, developing, building,...

The way in which people perceive climate change risk is informed by their social interactions and cultural worldviews comprising fundamental beliefs about society and nature....

Electron density in the topside ionosphere has significant variations with latitude, longitude, altitude, local time, season, and solar cycle. This paper focuses on the global...

Speleothem records from the South Asian summer monsoon (SASM) region display variability in the ratio of O-18 and O-18 (delta O-16) in calcium carbonate at orbital frequencies....

When compared with differences in snow accumulation predicted by widely used hydrological models, there is a much greater divergence among otherwise "good" models in their...

In this work we show how it is possible to derive a new set of nudging equations, a tool still used in many data assimilation problems, starting from statistical physics...

The formation of organic nitrates during the oxidation of the biogenic hydrocarbon isoprene can strongly affect boundary layer concentrations of ozone and nitrogen oxides (NOx =...

Geoengineering with stratospheric sulfate aerosols has been proposed as a means of temporarily cooling the planet, alleviating some of the side effects of anthropogenic CO₂...

Large wind farms are expected to influence local and regional atmospheric circulations. Using a mesoscale parameterization of the effects of wind farms that includes a momentum...

We present OH observations made in Amazonas, Brazil during the Green Ocean Amazon campaign (GoAmazon2014/5) from February to March of 2014. The average diurnal variation of OH...

Although optical components in Fourier transform infrared (FTIR) spectrometers are preferably wedged, in practice, infrared spectra typically suffer from the effects of optical...

Reconstructing past climates remains a difficult task because pre-instrumental observational networks are composed of geographically sparse and noisy paleoclimate proxy records...

This document is a description of the design, implementation, and operation of the third-generation NCAR General Circulation Model (GCM). It contains the information needed by...

The Global Positioning System (GPS) Radio Occultation (RO) is an active remote sensing technique, which is complementary to passive microwave and infrared sounders and microwave...

Variability in the ionosphere during the 2020-2021 sudden stratospheric warming (SSW) is investigated using a combination of Constellation Observing System for Meteorology,...

This paper describes development of a method for discriminating high ice water content (HIWC) conditions that can disrupt jet-engine performance in commuter and large transport...
