Site assessment and selection

Group picture time
Of course you wouldn’t call it a real campaign without decent group photo. Therefore, here it comes even in duplex version, the traditional, well-established ground based photography and the more fancy view from a camera drone.
Sounds of Science: Episode 01 – ANSWER
The sounds you hear come from our Scintec MFAS Sodar, which provides vertical profiles of the 3 dimensional wind field, up to around 500 m. You can read more about it here.
Sounds of Science: Episode 01
Good morning from the ice! We’re approaching the mid-way point of the campaign, here in Hailuoto, and we’ve grown accustom to some familiar daily sounds. Watch the clip below, and comment with your guess on what ISOBAR instrument you hear (hint: check out our instrumentation pages, to narrow your possibilities). We’ll post the answer later Read More …
Measurement Marathon
Today at 10 local time we finalized our first Intensive Observational Period after 22 hours of high activity. We captured an interesting case of a wintertime boundary layer transition, starting with air temperatures of -3 C at noon of February 10 that gradually decreased to close to -10 C towards the end of the IOP. Over the same time surface Read More …
And so it begins…
This morning the decision was made to make today our first Intensive Observational Period (IOP). With forecasts for the clearest night time conditions we’ve had since first arriving in Hailuoto, we will have a chance to work the kinks out of our procedures. Conditions are quite windy, and unfortunately the GFI team’s first SUMO profile Read More …
What do you do when it’s too windy to fly?
What do you do when you can’t fly UAVs? Eat, of course. The food here at Hailuodon Majakkapiha has everyone keeping a careful eye on the clock, since you don’t want to risk being late. Knowing that a hearty bowl of Salmon dill soup is waiting for you makes checking on ground stations in 10 m/s winds Read More …
Practice, practice, practice
They say it takes 10 000 hours to master a skill. If that’s true, we have a long way to go, but you have to start somewhere. This morning, the GFI team started conducting our first independent flights with the SUMO, though still under the watchful tutelage of Martin and Christian. It was especially paramount Read More …
Honing our aerial skills
The last two days have been very busy ones, with a real focus on getting our UAV operations off the ground (pun intended). We have been joined by colleagues from the University of Oklahoma, who also bring multiple UAV platforms with them. Unfortunately, the luggage issues we have all suffered so far have continued to Read More …
Site installations finished
With the end of the initial setup in sight, we all dug down deep and have now finished installing all of our instrumentation sites. Our SODAR system has been running since noon, and will be providing us with valuable details on the structure of the 3 dimensional winds in the boundary layer. Being such a Read More …
Installation
The last three days we’ve been busy preparing our 10-m mast and today it could finally be erected. Now we are sampling data on turbulence at three different levels. Three additional levels with standard observations on horizontal wind, temperature and humidity will give more detailed insight in the vertical gradients. So everything is running and Read More …
