Updates on the ISOBAR campaign on Hailuoto, Finland
Today we are a bit confused! All weather forecasts agree fully (that didn’t happen so often here before during the last weeks) and predict perfect measurement conditions for the coming night. Temperatures below -15 C and relatively weak winds. Thus the best perspectives for IOP7, the last one during the Hailuoto2018 experiment. Unfortunately, our colleagues Read More …
We’re nearing the end of our campaign, with tonight being our last IOP. So you only have a couple more days to guess some ISOBAR Sounds of Science!
Though it’s not very loud, the gentle whirr you hear is coming from one of three aspirated temperature sensors on our 10 m tower. We also have one of these sensors on our secondary mast, 70 m away.
You may have noticed that the Sounds of Science have been absent during the past few days. Though the clips are short, they still take some time to prepare, and over the course of five straight IOPs we exhausted all the prepared material. But now we’re back! See if you can figure out what an Read More …
While doing quadcopter profiles, you can get pretty cold. It’s mostly waiting, holding the remote, or laptop and staring intently upwards. But when you turn around and see this behind you, the warmth seems to return to your numb fingers.
We love weather; you might have gathered that. So when we see something new in the atmosphere that we’ve never seen before, we get really excited. This picture was taken 20Feb, just after 2 pm local. The sun is directly behind the camera, and off in the distance a white icebow tops the horizon. The Read More …
Another beautiful sunrise marks the end of IOP6 that started at 17 local time late afternoon yesterday. The conditions were a bit different from the forecast, but nevertheless, very interesting to cover. With mid level clouds coming in, the temperatures close to the ground increased from -15 and peaking at -11 C around 3 in the night, before dropping Read More …
A wrong word can destroy friendships, or as in our case, force a change of plans for our IOP5. When calling in at 5 this morning to deactivate the Danger Zone “Hailuoto West”, we are flying in, I used the phrase “….we are done for the day…” instead of ” …. we are done for the night….”. Therefore Read More …
During the last SUMO flight of IOP4, we launched with a broken cloud base around 150-200 m. By the end of the flight, about 30 mins later, the fog had rolled in, and drastically reduced visibility. Not only that, but during the final stage of landing, we noticed on the Ground Control Station that the Read More …
IOP4 is now over after fog came rolling in and caused heavy icing on the SUMO at around 3:30 local time last night. Before that, we measured several cold pool events with up to 4°C difference over a vertical distance of 5 meters. The first pronounced cold pool event started at 14 UTC and ended Read More …
