This infographic shows numbers on SCISAT, a small Canadian satellite that monitors ozone in the stratosphere and helps scientists improve their understanding of ozone depletion, with a special emphasis on the changes occurring over Canada and in the Arctic.
Here are the numbers and the explanations:
- Launch in 2003. The satellite was launched on August 12, 2003.
- 74° inclination. In order to collect data over a large part of the Canadian Arctic, SCISAT orbits Earth at an angle of 74° in relation to the equator.
- 2 instruments. Equipped with two optical instruments, SCISAT measures the distribution of gas species in Earth's atmosphere.
- 34 publications per year. SCISAT data is found in 34 scientific journal articles per year on average.
- 450 institutions. About 450 institutions worldwide have been involved in publications related to SCISAT.
- 70 trace gases. SCISAT measures more gases than any other space-based instrument in the world.
- 15 orbits per day. SCISAT completes an orbit every 95 minutes or so, meaning that it circles Earth about 15 times per day.
- Altitude of 650 km. SCISAT orbits Earth at an altitude of 650 km.
6316 solar occultations per year on average. SCISAT experiences many sunrises and sunsets in a day. At those times, it takes various measurements using the Sun’s rays passing through Earth's atmosphere. This technique is called solar occultation.
