SCoPEx: Stratospheric Controlled Perturbation Experiment SCoPEx is a scientific experiment to advance understanding of stratospheric aerosols that could be relevant to solar geoengineering.
What is the experiment? We plan to use a high-altitude balloon to lift an instrument package approximately 20 km into the atmosphere. Once it is in place, a very small amount of material (100 g to 2 kg) will be released to create a perturbed air mass roughly one kilometer long and one hundred meters in diameter. We will then use the same balloon to measure resulting changes in the perturbed air mass including changes in aerosol density, atmospheric chemistry, and light scattering.
What material will be released? In the future, if a science flight is approved by the independent Advisory Committee, we plan to release calcium carbonate, a common mineral dust. We may also release other materials such as sulfates in response to evolving scientific interests.
For more background, sulfate aerosol (chemically sulfuric acid) is one of the most studied materials for stratospheric aerosol geoengineering because it already exists naturally in the stratosphere. This means that researchers have some level of understanding of its potential effects even though there are still many uncertainties. However, this also means we know that sulfate aerosol, despite its potential benefits, has two major first order stratospheric impacts: ozone destruction and stratospheric heating. The dangers of ozone destruction are fairly well documented, but stratospheric heating is a poorly understood risk because we don’t yet understand how it could change the dynamics of the stratosphere (the motion of the stratosphere).
Do other environmental science experiments release materials outdoors? Yes. A number of environmental science experiments release or have released materials outdoors to create controlled perturbation for the same essential reason as we plan to do in SCoPEx—to directly control an experimental variable, which is crucial to scientific understanding. Examples of experiments include Free-Air Carbon Dioxide Enrichment (FACE) experiments, which release ozone and carbon dioxide (CO2) in the air for long durations to understand the impacts of climate and air pollution on crops and natural ecosystems; or Dispersion of Air Pollution and its Penetration into the Local Environment (DAPPLE) experiments, which have released sulfur hexafluoride (SF6) and perfluoromethylcyclohexane into urban air to study the transport of air pollutants.
What is the location and timing of the first flight? We formally asked the independent SCoPEx Advisory Committee to review our plans for a proposed platform test in Sweden in June 2021. In March 2021, the Advisory Committee recommended that we suspend the platform test until a more thorough societal engagement process can be conducted to address issues related to solar geoengineering research in Sweden.
How often are stratospheric balloons flown? Because this is not the science flight, the platform test is a rather standard stratospheric balloon flight when viewed in the context of other balloon flights. In 2019, for example, estimates suggest there were more than 300 stratospheric balloon flights over the course of the year.

Zweden heeft geweigerd om haar luchtruim beschikbaar te stellen voor het experiment ( voorzien voor juni 2021)
SSC has had dialogues this spring with both leading experts on geo-engineering and with other stakeholders, as well as with the SCoPEx Advisory Board. As a result of these dialogues and in agreement with Harvard, SSC has decided not to conduct the technical test flight planned for this summer.
The scientific community is divided regarding geoengineering, including any related technology tests such as the planned technical balloon test flight from Esrange this summer.” https://sscspace.com/.../no-technical-test-flight-for.../
An effort to dim the sun to stop global warming has been scrapped by the Swedish Space Agency, who announced that the program, funded by Bill Gates, has ‘divided the scientific community’ and will therefore not be carried out.
The Gates funded idea would have seen the release of calcium carbonate, essentially chalk dust, into the atmosphere from a high-altitude balloon to observe the effect it has on sunlight reaching the planet surface.
The ultimate goal of the study was to reduce the temperature on the planet in an effort to stave off global warming.
However, not surprisingly, the notion of blocking out the Sun proved somewhat unpopular, with environmental groups warning of potential “catastrophic consequences.” The Saami Council, an advocate group for Sweden’s indigenous population, warned that the Gates experiment “essentially attempts to mimic volcanic eruptions by continuously spewing the sky with sun-dimming particles.”
The group also pointed out that SCoPEx could have “irreversible sociopolitical effects” and would do nothing to reduce Carbon emissions, which are touted as the leading cause of climate change.
Essentially, the whole idea comes off as a weird vampirish effort to starve the planet of sunlight, the driver of all life, with little scientific logic behind it at all. Bill Gates, who is flogging a book about climate change, has poured millions into geoengineerng, funnelling at least $4.6 million to the lead researcher on SCoPEx, Harvard applied physics scientist David Keith.
Alles is klaar voor dit experiment. Gezien Zweden geweigerd heeft zal het ergens anders plaats vinden ( er worden gekeken naar de US ).
Wist u trouwens dat SCoPEX in 2019 meer dan 300 stratosferische ballonvaarten heeft verricht voor andere experimenten ?
Ik wist het niet, wegens.... niet op het nieuws.
