Partner for Navita Space Hackaton

We are happy to tell we are partners for the Navita Space hackaton, to be held in Linköping, Sweden in the weekend of April 22-24. It’s part of the NASA Space Apps Challenge, where volunteers from various backgrounds come up with ideas and solutions to challenges posed by NASA, using their vast public data. The best project goes on to compete against projects from other cities and can win a price and recognition.

Sparv will present Windsond and the capabilities of our sensors at the hackaton and encourage groups to come up with projects that use our tech. Especially the challenges in the Earth category are suitable for us.
There are a lot of possibilities how our tech can be used, and this is also a chance to get to know creative people and other companies. Everyone is welcome to join to watch or participate!

VORTEX-Southeast has started

Interactive hurricane tracker

The big USA tornado study VORTEX-Southeast has started. Data is now being collected from Windsond and all kinds of other instruments!

Here is a CNN article about the project.


A big research field project is now starting in USA: VORTEX-Southeast

It’s a continuation of a series of projects that aim to learn how to predict tornadoes. An Alabama newspaper covers the story.

We are happy to report that Windsond will be used in this project. With the small balloon size, Windsond is easier to use than traditional radiosondes in a field campaign where the ever-shifting atmospheric conditions makes it hard to know the most suitable launch point in advance.

Interview with sky lantern project Mboitata

We have reported a few times about the Mexican/Brazilian project Mboitata that uses Windsond to track large sky lanterns. Here is a nice interview from Facebook with Márcio Grochocki, a driving force in the project. Unfortunately the video is in Spanish. The white Windsond cups can be spotted throughout the video.

Back from AMS 2016 meeting

Last week Anders participated in the annual meeting of American Meteorological Society (AMS).


On Sunday, Anders joined WeatherSTEM at the WeatherFest event to educate children on weather and climate. Windsond uses very little helium and is reusable, which makes for low costs and makes it suitable in education for all ages.

After WeatherFest followed four days of conference, with talks on a wide range of topics, poster viewing and a commercial exhibit.

Just a look at the number of parallel sessions gives an idea of the size of the conference

In the spare time, New Orleans offered a nice paddle boat tour on the Mississippi

Thanks to everyone that talked with us about Windsond, UAV, boundary layer meteorology and more!
Don’t hesitate to get in contact to continue discussing.

2016 New Year Reflections

fireworksAs 2015 turns into 2016, it’s time to reflect on Windsond and its role in the world. There are also reflections for Sparv Embedded, the company behind Windsond.

First, I want to direct a big ‘Thank You’ to the customers and others who give valuable input on how you wish to use Windsond and how we can improve the system.

2015 was the year when Windsond started gaining a wider circle of customers. Previously, Windsond customers often had to learn of us by hearsay. During 2015 we visited ISARRA in Oklahoma and we exhibited at MTWE in Brussels. Here we got in contact with a much bigger range of customers and learned more of the market.

Business-wise, this also means a lot for our ability to put more resources into the further development of the system. 2015 has seen incremental updates to the system. Visible improvements include 1 hertz updates, support for eight simultaneous soundings, support for external sensors, on-board logging and some software improvements. In the background, we have improved our manufacturing capability, measurement accuracy etc. Now we have started to enhance Windsond from a basic radiosonde solution to a more versatile and polished system. This work continues into 2016.

The case for affordable and portable weather measurement systems is growing stronger. 2015 is shaping up to be the warmest year on record. Climate change continues to increase the frequency and severity of adverse weather events throughout the world. Right now, several big weather incidents are unfolding around the world.

In the USA, storms, floods, tornadoes and snow storms wreak havoc and kill dozens of people:

In northern England, excessive rains cause record floods and massive damage:

Several countries in South America also experience massive flooding due to a strong El Niño:

With respect to all human tragedy and economic damage, this highlights the pressing need for more pervasive measurements to improve weather forecasts for decision support. It’s our sincere wish to alleviate the suffering caused by sudden weather conditions by designing tools better suited for predicting these conditions. As we deal with the daily tasks of running a company, we must not lose track of this goal.

American Meteorological Society annual meeting

AMS16 Show Logo72ppi-smallUnderstanding and building a relation with our customers is crucial for us. It’s all too easy to develop products that perform well but perform the wrong task.

I (Anders) will go to the 2016 annual meeting of the American Meteorological Society (AMS) during January 10-14 to meet with customers and learn more about the ongoing research. I will also participate in a Windsond demonstration for schools during the WeatherFest fair on January 10th.

If you will be there too, do let me know!

Visit to United Arab Emirates

2015-12-08 12.55.34 edit-600px We visited a customer in United Arab Emirates.
They use Windsond since 1.5 years. They also have a Vaisala system, but prefer Windsond due to how easy it is to bring along and how easy it is it use.

Quoting the customer:
“With Vaisala, we need to bring a van dedicated to storing and operating the equipment and it takes two persons to use. Windsond can be operated from the trunk of the vehicle we would bring anyway. On our next field campaign, we will only bring Windsond.”

Report from FluxLite-3 high-altitude launch

The report from the October launch of a high-altitude scientific balloon with Windsond is now published here: KTH 2015 FluxLite-3 report

The experiment carried a muon detector. The external sensor interface of Windsond was used to read each measurement and incorporate it into the Windsond data feed to the ground. Windsond also logged all data using the onboard logging option.

Updated product catalogue

The Windsond product catalogue received a facelift for the MTWE expo.
Here is the new product catalogue (6.7 MB).

There’s also a a one-page product flyer (0.4 MB).
