Reports of the Intergovernmental Panel on Climate Change have stated that precipitation has changed by up to 1% for each decade in the 20th century [1]. Indeed, the Clausius Clapeyron equation predicts absolute humidity increases by about 7% for each degree of warming assuming no change in the relative humidity. This study analyzed monthly precipitation observations recorded at over 1,000...

Sulfur dioxide oxidation and the effect of oxidation products in formation and growth of aerosols have been studied widely. Despite this, significant gaps still exist in understanding the SO2 oxidation pathways in various locations. A study of SO2 and aerosol sulphate downwind of the oil sands region was conducted as part of the FOSSILIS campaign in the summer 2013. Size segregated aerosols...

The chaotic behavior of the space plasma in the polar region is analyzed and characterized. The study was carried out using the amplitude and phase components of the GPS (Global Positioning System) L1 signal time series sampled at 50 Hz. A stationary signal is obtained after removing the trend due to the background electron density variability and the Doppler shift due to the satellite...

534. Comparison of IGS Network GPS Receiver DCBs Provided by CODE and a Single Station Estimation Method

Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)

The Global Positioning System (GPS) is a valuable tool in the measurement and monitoring of ionospheric total electron content (TEC). To obtain accurate GPS-derived TEC, satellite and receiver hardware biases, known as differential code biases (DCBs), must be removed. A number of sources calculate and provide GPS satellite DCBs, one such source is the Centre for Orbit Determination in Europe...

511. Ionospheric Sounding Opportunities Using Signal Data From Pre-existing Amateur Radio And Operational Networks

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

Amateur radio and other signals used for dedicated purposes, such as the Automatic Position Reporting System (APRS) and Automatic Dependent Surveillance Broadcast (ADS-B), are signals that exist for another reason, but can be used for ionospheric sounding. Whether mandated and government funded or voluntarily constructed and operated, these networks provide data that can be used for scientific...

752. Determining the equatorial dayside plasma density using travel-time magnetoseismology

Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

Plasma density in the outer terrestrial magnetosphere is highly variable, both in space and time. Spacecraft observations are very sparse, and photoelectric charging makes direct in-situ measurements extremely challenging. In this report we present a new remote sensing method which could be a significant source of information about conditions in the dayside magnetosphere. This...

658. A Statistical Study of Drifts of Patchy Pulsating Aurora：Observed by THEMIS All-Sky Imagers

Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)

Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)

Patchy pulsating aurora (PPA) is a very common ionospheric phenomenon and thus offers us a unique opportunity to study the inner magnetospheric dynamics. It is usually excited by a few to 10s Kev electrons and occurs in the equatorward part of the auroral oval. Many previous studies have been done to investigate the motion of PPA patches, but none of them were based on a large dataset. In this...

This work will present the analysis approach developed to detect of gravity waves and the variation in gravity wave parameters deduced from the airglow images taken by the Polar Environment Atmospheric Research Laboratory (PEARL) All Sky Imager (PASI). PASI has been in operation since November 2007 at PEARL in Eureka, Nunavut with images being taken on average every minute during the winter...

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

Arc-like auroral structures in the polar cap often move in the dawn-dusk direction. Speeds of such motions vary between ~100 m/s and 2 km/s depending on the magnetic local time of observations. In the midnight sector, typical speeds of 300-500 m/s have been reported. We show that these values are somewhat larger than plasma flow speeds in the zonal direction typically observed by the Clyde...

The Herschel Space Observatory, Herschel, is a flagship mission of the European Space Agency operational from 2009-2013 with Canadian participation supported by the Canadian Space Agency. Herschel has enabled ground-breaking astrophysical observations through providing the first unfettered access to the far-infrared region of the electromagnetic spectrum. The Herschel Gould Belt Survey (GBS)...

ABOVE, the Array for Broadband Observations of VLF/ELF Emissions, is a network of radio instruments located across western Canada. The instruments monitor natural and artificial electromagnetic radiation in the frequency range from 200 Hz to 75 kHz. The primary scientific focus is on energetic particle precipitation: we infer precipitation into the atmosphere based on the observed amplitude...

We report first results on energetic electron precipitation using the recently deployed ABOVE array. ABOVE is a ground-based array of Very Low Frequency (VLF) radio receivers located across western Canada. With the new instruments, we characterize the properties of electron precipitation during a geomagnetic storm using changes to the phase and amplitude of VLF radio waves from ground based...
