Right now of the yr, the point out of Lapland conjures up visions of Santa getting his gift-laden sleigh and 9 reindeer able to take to the skies for crucial deliveries of all. Nevertheless, the skies of Lapland have witnessed one thing fairly completely different just lately—an enormous white balloon, which can not present the instant gratification of a much-wanted Christmas current, however nonetheless performs a job in serving to to safeguard our kids’s future.


The balloon in query was launched to measure the quantity of carbon dioxide and methane within the ambiance and is a part of ESA’s preparatory work for the brand new Copernicus Carbon Dioxide Monitoring satellite mission.

Dr. Hannakaisa Lindqvist, Head of the Greenhouse Gases and Satellite tv for pc Strategies Group on the Finnish Meteorological Institute (FMI), defined, “What a sight it was. From the center of the thick boreal forest on a chilly winter’s day, we watched the balloon rise from the snowy floor and develop in opposition to the cloudless blue sky.

“Connected to the hydrogen-filled white balloon was a field that held an vital instrument referred to as AirCore.”

Increasing to its limits, the balloon finally burst when it reached greater than 30 km above the forest.

Then, because the balloon items began falling, a parachute opened and introduced AirCore slowly again to the bottom.

On its journey again by the ambiance, AirCore collected measurements of molecules within the air that flowed by the instrument’s tubing—souvenirs from completely different heights.

To stop the molecules from mixing, the instrument needed to be collected as quick as potential after touchdown.

The institute’s researchers have developed wonderful instruments for forecasting the touchdown, which assist cease it from ending up in open water, cities or different troublesome locations.

The entire level of this elaborate experiment is to extend information of the composition of the ambiance at completely different altitudes over the Arctic—specifically, to grasp the vertical distribution of greenhouse gases.

“And, extra particularly, the purpose is to judge the feasibility of carbon dioxide observations over snow.

“Opposite to our on a regular basis expertise, snow could be very darkish on the wavelengths that greenhouse-gas measuring satellites observe—which is the place the brand new Copernicus Carbon Dioxide Monitoring mission is available in,” added Dr. Rigel Kivi, the Principal Investigator of the AirCore observations on the FMI House and Earth Commentary Middle in Sodankylä.

The Copernicus Anthropogenic Carbon Dioxide Monitoring mission, or CO2M for brief, is certainly one of six Copernicus Sentinel Growth missions that ESA is creating on behalf of the EU.

It’s deliberate as a two-satellite mission, with the choice of a 3rd satellite.

They’ll every carry a near-infrared and shortwave-infrared spectrometer to measure atmospheric carbon dioxide at excessive spatial decision.

These measurements will likely be utilized by the brand new CO2M Monitoring and Verification Assist Capability, which the European Middle for Medium-Vary Climate Forecasts is creating, and which can finally cut back uncertainties in estimates of emissions of carbon dioxide from the combustion of fossil gas at native, nationwide, and regional scales.

This may present the EU with a singular and unbiased supply of knowledge to evaluate the effectiveness of coverage measures, and to trace their impression in direction of decarbonizing Europe and assembly nationwide emission discount targets.

Furthermore, nations all through the world will be capable of assess and evaluate with transparency how they’re assembly their targets.

On a technical degree, at excessive latitudes, the mission must make observations when there may be little daylight and over snow surfaces, however nonetheless excel in accuracy and precision.

Yasjka Meijer, ESA’s CO2M mission scientist, mentioned, “The latest balloon experiment helps analysis into bettering CO2M’s measurements over the Arctic. That is particularly related for measuring methane emissions from the fuel business and from thawing permafrost in northern latitudes.”

Whereas the researchers analyze the information from this explicit balloon flight, we’re assured that the sight of a balloon taking to the skies over Lapland hasn’t deterred Santa from his personal upcoming mission.
