From 2004 to 2006 an observational array of current- and pressure-recording inverted echo sounders (CPIES) were deployed as part of the Kuroshio Extension (KEx) System Study...

A method for mapping the dynamics of the South Asian monsoon season is proposed based on the use of the coherence of CYGNSS Level 1 delay-Doppler Map measurements. Because the...

Solar soft X-ray (XUV) radiation is highly variable on all time scales and strongly affects Earth's ionosphere and upper atmosphere; consequently, the solar XUV irradiance is...

The processes occurring in the tropical tropopause layer (TTL) are of great importance for stratosphere-troposphere exchanges and the variability of the Earth's climate....

This paper reports the characteristics of the topside ionospheric O+ diffusive flux (phi O+) during both geomagnetically quiet (0 <= Kp <= 2) and moderate (2 < Kp <=...

Obituary of John W. Firor, a former Director of the High Altitude Observatory and the National Center for Atmospheric Research, and a founder of the Solar Physics Division of...

Recommendations are presented regarding the composition and accessibility of the Facilities for Atmospheric Research and Education (FARE), funded by the U.S. National Science...

A suite of numerical experiments were conducted to investigate the sensitivity of the tropical cyclone (TC) motion—western Pacific subtropical high (WPSH) intensity...

Concentrations of fine particulate matter (PM2.5) that exceed air quality standards affect human health and have an impact on the earth's radiation budget. The lack of round the...

A thermospheric O and N-2 column density ratio (Sigma O/N-2) depletion with long-duration (>16 hr) was observed by the Global-scale Observations of the Limb and Disk at the...

To understand its evolution and the effects of its eruptive events, the Sun is permanently monitored by multiple satellite missions. The optically thin emission of the solar...

Air pollution experienced by expanding urban areas is responsible for serious health effects and death for millions of people every year. Trash burning is a common disposal...

We present a boundary data-driven magnetohydrodynamic (MHD) simulation of the 2011 February 15 coronal mass ejection (CME) event of Active Region NOAA 11158. The simulation is...

Alpine tundra ecosystems are highly vulnerable to climate warming but are governed by local-scale abiotic heterogeneity, which makes it difficult to predict tundra responses to...

The identification of vortices in a fluid flow is a dynamically interesting problem that has practical applications in oceanography due to the outsized role eddies play in water...

In the present paper, we aim to reduce the discrepancies between tsunami arrival times evaluated from tsunami models and real measurements considering the role of ocean...

We describe a global atmospheric data assimilation scheme that has been adapted for use with a Martian General Circulation Model (GCM), with the ultimate goal of creating...

Direct numerical simulations (DNS) at bulk Reynolds number Re = 10(4) and bulk Richardson number Ri = 0.25 of plane Couette flow are performed with the results used to analyze...

For scientific array-based programs, optimization for a particular target platform is a hard problem. There are many optimization techniques such as (semantics-preserving)...

Tracer-tracer relations have been used for a long time to separate physico-chemical change from change caused by transport processes. In particular, for more than a decade,...
