Download the following documents to learn more about the Swarm mission and its products. The definition and justification of Level 1b data is documented in, Level 2 data and auxiliary products are documented in and of the ESA Swarm study under ESA contract no. By a complex assimilation of these individual satellite measurements into one set of products for the satellite constellation, the Level 2 Processor ensures a very significant improvement of the quality of the final scientific data products. The Swarm Level 1b data products are the corrected and formatted output from each of the three Swarm satellites. The product handbook is intended to support the use of the products for further processing or application. These products include Swarm magnetic field models, ionospheric and thermospheric products, and Precise Orbit Solutions including supporting information.

In the meantime, it was a nice afternoon chatting and mixing art and science in equal measure. In the evening we will go back and record some audio from the antenna which will be used in an installation r a d i o q u a l i a has in Italy in April. Additionally, it was interesting to learn about the rarity of whistlers (caused by large electromagnetic events such as nuclear explosions or lightning strikes), and other sounds that can cause interference with VLF observations and cause problems for scientists (such as emissions from submarines). This is a very interesting phenomenon, peculiar to VLF, and it has been suggested that VLF communication could exploit the earthвЂ™s magnetic field in a similar fashion and produce a highly efficient long range communications system. For example, the sounds we were hearing could have been occurring directly above us in the earthвЂ™s ionosphere, but equally, they could have been occurring in the Northern Hemisphere and being communicated here by the earthвЂ™s magnetic field. One of the most interesting things is that VLF travels along the earthвЂ™s magnetic field, which means you have points of mirror-like reflection. Remmy explained to me quite a lot about VLF. The scene cut quite a mix of the familiar and the bizarre, and I had to tell myself I must remember this moment as itвЂ™s not every day you see a space scientist sitting on a rock fishing for rare radio waves. There were plenty of rocks for us to lie comfortably on, the sun was out and the wind was almost non-existent. About 800m from the base and overlooking a huge plateau. The place we chose to set it all up is pretty beautiful. Next, we will do some longer soundings and record the output. So our tests were relatively short lived, we really went to test the set-up and see how it operated. We were hoping to hear some other sounds like the fabled whistlers, but these are rare, especially this time of year. They sound (in RemmyвЂ™s words) like fat frying in a frying pan. The little INSPIRE VLF receiver worked wonderfully and we could listen to the sferics. It was exciting as Remmy is a space scientist specialising in VLF and he had never heard live VLF sounds before. We then connected it all up and plugged in the headphones.

So we got as far away from power sources as was practical and dug the earth cable into some rocks. The problem with VLF is that if you are close to power sources (cables etc), the receiver will pick it up and all you will hear is hum. We grabbed it and the receiver and headed off after lunch to a nice quiet spot about 800 metres away from the base. The VLF antenna itself is about 3 metres long and looks like a long fishing rod. Then we made a nice antenna cable to run between the receiver and the antenna, and an earth cable. So we located an extra filament and reconstructed it.

It was sitting on the roof of the base but got destroyed in a storm. Remmy and I had renovated a VLF antenna from the base just 2 days ago. It is the type of tuner that people use to listen to the auroras, but it conjures up some interesting sounds at any time. The VLF receiver allows you to tune in to, and listen, to the earthвЂ™s ionosphere. So today I decided it would be great to try out the Very Low Frequency (VLF) antenna and receiver with Remmy.
