This study documents and describes supercells embedded within the outer rainbands of Hurricane Katrina (2005). Radar reflectivity and velocity data collected on 29 August 2005...

In this study, the variability of the spectral dispersion of droplet size distributions (DSDs) in convective clouds is investigated. Analyses are based on aircraft measurements...

Gridpoint Statistical Interpolation (GSI) is an assimilation tool that is used at the National Centers for Environmental Prediction (NCEP) in operational weather forecasting in...

Climate warming is unequivocal and exceeds internal climate variability. However, estimates of the magnitude of decadal-scale variability from models and observations are...

In this paper we examine a low-energy solar energetic particle (SEP) event observed by IS circle dot IS's Energetic Particle Instrument-Low (EPI-Lo) inside 0.18 au on 2020...

As droughts have widespread social and ecological impacts, it is critical to develop long-term adaptation and mitigation strategies to reduce drought vulnerability. Climate...

This document discusses selected aspects of the NCAR computer hardware systems and some of the considerations involved in choosing data formats. It also describe some of the...

The Canopy Horizontal Array Turbulence Study (CHATS) took place in spring 2007 and is the third in the series of Horizontal Array Turbulence Study (HATS) experiments. The HATS...

Hydrogen fluoride (HF) is often used as a simple reference for other column observations of chemically active stratospheric species. However, seasonal and shorter timescale...

Using the climate feedback response analysis method, the authors examine the individual contributions of the CO₂ radiative forcing and climate feedbacks to the magnitude,...

This represents a collection of papers written by graduate students participating in the 1977 Summer Fellowship Program in Scientific Computing. Included are brief descriptions...

The influence of the Atlantic multidecadal variability (AMV) on the North Atlantic storm track and eddy-driven jet in the winter season is assessed via a coordinated analysis of...

Report on a complete theory development that gives an exact calculation for all angles with irrotational flow around a sphere, the easiest shape for a nose radome which includes...

We present in situ ion composition and velocity measurements during the August 2017 solar eclipse from the Enhanced Polar Outflow Probe (e-POP), which crossed the path of...

The manuscript is an attempt to present in a single document the various types of confidence intervals, their assumptions, and other issues as they pertain to forecast...

The daytime O(¹S) emission at 557.7 nm observed at 250 km with the Wind Imaging Interferometer (WINDII) is dominantly excited by photoelectron impact on atomic oxygen, so the...

The Orbiting Carbon Observatory-2 has been on orbit since 2014, and its global coverage holds the potential to reveal new information about the carbon cycle through the use of...

Radiosonde humidity data provide the longest record for assessing changes in atmospheric water vapor, but they often contain large discontinuities because of changes in...

This study evaluates the representation of precipitation in a set of multi-year convection-permitting sensitivity experiments over the European Alpine region. In the last few...

The supereruption of Los Chocoyos (14.6 degrees N, 91.2 degrees W) in Guatemala similar to 84 kyr ago was one of the largest volcanic events of the past 100 000 years. Recent...
