Polar Research Ionospheric Doppler Experiment (PRIDE)

The project will use a simple radio system to measure waves in the upper atmopshere (ionosphere) above Svalbard.

Great to see you here!

Did you know that there are {{related}} projects registered now with keywords matching your project, and {{close}} projects with fieldwork within 10km of your fieldwork site?

check them out here!

Thank you for adding your research project to the growing pool of knowledge about the research going on in Svalbard and its surrounding waters!

As we would like you to know a bit about what is going on in Svalbard in your discipline and fieldwork surroundings, we have selected some projects that should be interesting for you to have a look at. There are {{related}} projects registered in RiS that match with your keywords, and below you will find links to the 3 that have the most relevant match.

As we all work to reduce our environmental footprint, we want to give you an easy way to find projects that have fieldwork close to you, so you can contact the project owner and coordinate your logistics whenever possible. This could also help you save some expensive costs ;) There are {{close}} projects registered in RiS that have registered their fieldwork sites within 10 km from you, and below you will find links to the 3 closest fieldwork locations.

Summary

A low power (20W), single frequency HF transmitter, located at the Polish Research Base in Hornsund, will transmit a signal into the ionized part of the upper atmosphere (the ionosphere), where it is reflected at an altitude of ~200km before being received at the Kjell Henriksen Observatory in Longyearbyen. The reflection altitude will change depending on various ionospheric processes such as Gravity Waves or ULF (Ultra Low Frequency) waves. This change in altitude will be registered as a doppler shift of the received signal. The experiment will allow us to continuously monitor the wave structures in the ionosphere (magnitude, frequency, local time dependence, geomagnetic dependence..) which can provide information about various energy transfer processes. The antenna will be a simple half wave dipole design and once deployed, (using existing infra-structure) requires no additional input (other than occasional maintenance from personnel at Hornsund). The transmitter unit will be stored in zargess box at the base of the antenna and again requires no additional input once switched on (other than occasional maintenance, if a fault develops, from personnel at Hornsund). The receiver system is already in place at the Kjell Henriksen Observatory. We plan to deploy the system iat the Polish Research Base in Hornsund in summer 2020, depending on availability of transport to the research base. It should take a few days to deploy.
