Contributions of dust and biomass burning to aerosols at a Colorado mountain-top site [PDF]
Atmospheric Chemistry and Physics, 2015 Visible Multifilter Rotating Shadowband Radiometer (vis-MFRSR) data were collected at Storm Peak Laboratory (SPL), a mountain-top facility in northwest Colorado, from 1999 to 2011 and in 2013.

Whether duration of the recovery phase of magnetic storm depends on the development rate of storm at its main phase? [PDF]
Geomagnetism and Aeronomy, Vol. 55, No. 4, pp. 421-424, 2015, 2014 We compare dependences between the storm development rate $|Dst_{min}|/\Delta T$ ($\Delta T$ is the durations of main phase) and the duration of recovery phase of magnetic storms generated by three various types of interplanetary drivers: (1, 2) compression regions CIR and Sheath, and (3) body of interplanetary CME (magnetic clouds and Ejecta).

R-Storm: Resource-Aware Scheduling in Storm [PDF]
In Proceedings of the 16th Annual Middleware Conference
(Middleware 2015). ACM, New York, NY, USA, 149-161, 2019 The era of big data has led to the emergence of new systems for real-time distributed stream processing, e.g., Apache Storm is one of the most popular stream processing systems in industry today. However, Storm, like many other stream processing systems lacks an intelligent scheduling mechanism.

Characteristics of flight delays during solar flares
Scientific Reports, 2023 Solar flares are one of the severest solar activities that have important effects on near-Earth space. Previous studies have shown that flight arrival delays increase as a result of solar flares, but the intrinsic mechanism behind this relationship is ...

Satellite orbital drag during magnetic storms [PDF]
Published in Space Weather, 2019, volume 17, 2019 We investigate satellite orbital drag effects at low-Earth orbit (LEO) associated with thermosphere heating during magnetic storms caused by coronal mass ejections. CHAllenge Mini-satellite Payload (CHAMP) and Gravity Recovery And Climate Experiment (GRACE) neutral density data are used to compute orbital drag.
