Atmospheric Science Data
Canada's SCISAT satellite measures chemical molecules (over 40 atmospheric gases) that influence the distribution of ozone in the stratosphere.
Since 2003, SCISAT has monitored ozone in the stratosphere and helped scientists understand the depletion of the ozone layer, especially over Canada and in the Arctic.
OSIRIS is a Canadian Optical Spectrograph and InfraRed Imaging System. Located on the Swedish Odin satellite, it measures concentrations of ozone, aerosols and nitrogen dioxide in the upper atmosphere.
Since 2001, OSIRIS has helped scientists better understand the impact of human activities and natural phenomena on the environment and climate.
MOPITT is a Canadian instrument aboard the Terra satellite. It measures carbon monoxide concentrations in the high atmosphere. Its data are used to assess the scope of certain pollution control initiatives and to help understand environmental effects of other human activities such as biomass burning.
Since 1999, MOPITT has contributed to the study of environmental pollution by continuously scanning the troposphere to make long-term measurements of carbon monoxide concentrations. Initially planned for a five-year term, this experiment has been prolonged because the data collected is still of high quality and the satellite is in good health.
CloudSat is a NASA satellite that has been gathering data on clouds structure, occurrence and volume to improve our knowledge of clouds and their effect on climate and weather.
Launched in 2006, it contains two key elements that are Canadian: the extended interaction klystrons (EIKs), as well as a central component of an electronic receiver (RFES). A klystron is a specialized electronic tube that generates radar waves. CloudSat uses its klystrons to probe the vertical structure of clouds.
Space Environment/Space Weather Data
The ePOP probe, aboard Canada's CASSIOPE satellite, observes the Earth's ionosphere, where space meets the upper atmosphere. It collects data on the effects of solar storms and, more specifically, their harmful impact on radio communications, satellite navigation and other space and ground-based technologies.
The e-POP science payload carries a suite of eight science instruments, including imaging plasma and neutral particle sensors, magnetometers, radio wave receivers, dual-frequency GPS receivers, Charge Coupled Device cameras, and a beacon transmitter.
The three satellites of the European Swarm mission precisely measure the magnetic fields generated from Earth's core, mantle, crust, oceans, ionosphere and magnetosphere. By observing the complexities of Earth's protective magnetic shield, Swarm is providing insight into many natural processes.
The Canadian Electric Field Instrument on Swarm provides high-precision data on ionospheric winds to characterize the electric field around Earth.
The Canadian Array for Realtime Investigations of Magnetic Activity (CARISMA), previously known as CANOPUS, is the magnetometer element of the Geospace Observatory Canada project and is operated by the University of Alberta.
Magnetometers are used to measure disturbances in the Earth's magnetic field caused by activity occurring in the magnetosphere, a region of space near the Earth.
Launched on September 29, 1962, the Alouette-I scientific satellite marked Canada's entry into the space age and was seen by many as initiating the most progressive space program of that era. In its first three months of operation, Alouette-I's four scientific instruments produced some of the most exciting data on the status of the ionosphere. Almost 55 years later, the CSA has digitized more than 450 canisters of 35-mm film provided by the satellite, data with a rich historical value that is still of interest to scientists today.
Alouette's ionograms show details in the layers of the ionosphere that can help us understand subtle variations in signals that are transmitted by highly sophisticated Global Navigation Satellite Systems (GNSS) and telecommunication satellites.
Riometers passively monitor radio noise from extrasolar sources and have been shown to be an effective way to monitor high-energy electron populations in the region of space around the Earth.
An historic dataset was acquired from 1989 to 2007 through a pan-Canadian network of 11 riometers.
Earth Observation Data
Planned for launch in 2018, the RADARSAT Constellation Mission (RCM) is made up of three identical satellites. It is designed to build on Canada's Earth observation capabilities, particularly for maritime surveillance (ice, surface winds, oil pollution and ship monitoring), disaster management (mitigation, warning, response and recovery) and ecosystem monitoring (agriculture, wetlands, forestry and coastal change monitoring).
RCM will provide daily revisits of Canada’s vast territory and maritime approaches, as well as daily access to 90% of the world’s surface. It will also significantly increase our coverage of the Canadian Arctic with up to four passes per day in Canada's far north, and several passes per day over the Northwest Passage.
More information on RCM
RCM simulated data over Vancouver is available, along with archived RADARSAT-1 and RADARSAT-2 products of the same area.
Two freewares that display and analyze RADARSAT-1 and RADARSAT-2:
A mosaic of Canada was developed in 2014 from 121 images captured by Canadian satellite RADARSAT-2. The data used to create these images was acquired from May 1 to June 1, 2013. The colour variation in the mosaic represents the changes in soil texture, roughness and the level of soil moisture.
Space Astronomy Data
Launched in 2003, the Microvariability and Oscillations of STars (MOST) is a Canadian microsatellite designed to monitor optical variability in a few stellar targets for up to 60 days. As the first telescope dedicated to astroseismology, MOST measured the oscillation in light intensity of stars in order to determine their composition as well as age. It also measured transit of known exoplanets. The Advanced MOST Science Archive is published in collaboration with the Canadian Astronomy Data Centre.
The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a 2-m telescope that has conducted a series of astronomy observation missions.
Built and flown by a collaboration of universities from Canada, the United States, the United Kingdom and Mexico, the telescope initially used a prototype of the Spectral and Photometric Imaging Receiver (SPIRE) camera for the Herschel satellite.
The Far Ultraviolet Spectroscopic Explorer (FUSE) was a NASA space telescope, led by Johns Hopkins University, and built in collaboration with the Canadian and French space agencies. It made high-resolution spectroscopic observations in the far-ultraviolet from 1999 to 2007.
Planetary Exploration Data
The data represent Laser-Induced Breakdown Spectroscopy (LIBS) emission obtained from 68 samples of rocks and minerals. The calibration table of known chemical content of the samples is also contained in the data.
