Arthropodborne viruses (arboviruses) have presented a health threat to humans throughout history. In recent years, however, high-profile arbovirus introductions and...

The impact of ice phase cloud microphysical processes on prediction of tropical cyclone environment is examined for two microphysical parameterizations using the Coupled Ocean-...

A characteristic feature of the main phase of geomagnetic storms is the dawn-dusk asymmetric depression of low- and mid-latitude ground magnetic fields, with largest depression...

This technical note serves several purposes. In Part I, the development of adjoints is described in general terms for spatially and temporally discrete models. In Part II, the...

This study evaluates a hypothesis for the role of vertical wind shear in deep convection initiation (DCI) that was introduced in Part I by examining behavior of a series of...

We study novel spectra from 310 nm to 5.5 mu m obtained during the 2017 August 21 eclipse. Four spectrometers were deployed at Camp Wyoba (altitude 2402 m) on Casper Mountain,...

Performance of the simultaneous multiple pulse repetition frequency algorithm (SMPRF) for recovery of mean power and mean Doppler velocity is investigated using simulated...

Dynamic Global Vegetation Models (DGVMs) provide a state-of-the-art process-based approach to study the complex interplay between vegetation and its physical environment. For...

In this study, a simple stochastic climate model is used to examine the impact of the ocean mixed layer depth, surface turbulent energy fluxes, and Ekman currents on the...

This document presents a comprehensive description of the Spectral Vegetation Radiometer (SVR) used on NCAR aircraft to derive information about the vegetation cover....

Global-mean surface temperature has experienced fast warming during 1985-98 but stabilized during 19992013, especially in boreal winter. Climate changes over East Asia between...

A warming climate is altering land-atmosphere exchanges of carbon, with a potential for increased vegetation productivity as well as the mobilization of permafrost soil carbon...

The Hurricane Rainband and Intensity Change Experiment (RAINEX) used three P3 aircraft aided by high-resolution numerical modeling and satellite communications to investigate...

In the past few decades, there has been an evolution in our understanding of soil organic matter (SOM) dynamics from one of inherent biochemical recalcitrance to one deriving...

Dry deposition is an important process affecting the lifetime and spatial distributions of atmospheric aerosols. Black carbon (BC) plays an important role in the Earth's...

Aerosol–cloud interactions continue to constitute a major source of uncertainty for the estimate of climate radiative forcing. The variation of aerosol indirect effects (AIE)...

This study presents digital flight data recorder (DFDR) analyses and high-resolution numerical simulations relevant to a severe clear-air turbulence (CAT) encounter over western...

Rimed hydrometeors (graupel or hail) are added to a stratiform cloud scheme for global models and tested in a variety of configurations. Off-line tests compare well to other...

The solar cycle variation of F₂ region winter anomaly is related to solar cycle changes in the latitudinal winter-to-summer difference of O/N₂. Here we use the National...

Leadership from the NCAR and NOAA modeling communities spearheaded an effort to identify collaboration opportunities in effort to advance weather and climate prediction...
