Caeli: The Sky Is Not the Limit in Measuring Particulate Matter in the Atmosphere

Measuring by Satellite

Caeli is a startup dedicated to providing insight into air quality with a view from above. The satellites orbiting our planet provide their end-users with chronological and (near) real-time information. Satellite imagery can be a cheaper and more readily available option than remote sensing as a tool for measuring the molecular composition of our atmosphere. Generating maps displaying particulate matter such as Nitrogen Dioxide (NO2), Ammonia (NH3), Methane (CH4) and Ozone (O3) can help the public and government understand how changes to the atmosphere may affect health or influence the climate.

An enormous amount of visual and quantitative satellite data needs to be processed to create these real-time insights. Copernicus Sentinel imagery offers Caeli historical insights to observe change in air quality over time. The raw multispectral and geographically calibrated source data must not only be able to be processed quickly but also organized chronologically and stored overtime in accessible files. The original Caeli database was not scalable enough to support these data streams, so we needed a new architecture. 

How Docker and Kubernetes’ Open Source Technology is Winning Over Businesses

By Young Mavericks’ Data Engineer Don de Lange

Data Engineers must ensure that technological solutions for companies can actually be implemented. In order to fulfil these technical promises in an increasingly complex data-driven world, like many other Data Engineers, I use various software and data tools. Docker and Kubernetes, two leaders in the field of open source technologies, help to build, manage and scale apps in containers. In this blog I explain what Docker and Kubernetes are, why more and more companies are taking advantage of their expertise and how you yourself can take advantage of these platforms.
