Current CloudCatcher Team

We are based in Harwell, Oxfordshire in the UK and work for RAL Space which is part of the UK Government's Science and Technology Facilities Council. Here at RAL Space, we do all sorts of activities relating to Earth Observation, from calibrating instruments prior to launch, to monitoring their performance when in space.

I am the main investigator for CloudCatcher and I've worked on clouds for some years, and it has been my job to develop and maintain one of the cloud identification processes for a satellite instrument. We can use what we know about clouds to help write instructions for the computer to be able to identify which pixels are cloudy or not. For example, we know that many clouds appear as very bright pixels in the images, and so we can instruct the computer to mask any pixels brighter than a certain number. We also know that clouds are very cold, so we can instruct the computer to mask any pixels colder than a certain temperature. The tricky thing is making a set of instructions that work well for every image over the globe!

I have looked at a lot of these satellite images, which is something I love to do, but I can only check so many! I thought it would be a great thing if we could get volunteers to to work with us on this.

When I am not in work, I can be found at home with my family.

Part of my job has been to make sure instruments are in good working order when it in space. I do this by checking their temperature (just like a Doctor!) and looking at the data sent down by the satellite. Very occasionally there are problems and the instrument stops working as well as it should and I have to work with the other teams of engineers and scientists from all over Europe to help fix the problem.

As part of CloudCatcher I will be collating the results that we gather and assembling the results we have to make a 'human cloud mask'.

When I am not in work, I can be found growing vegetables on my allotment.

I am part of the Communications team at RAL Space and I have been helping with the public engagement activities to introduce CloudCatcher to a wide audience.

Citizen Scientists (You!)

Thank you to all of our citizen scientists who provide the fundamental data needed for the success of the CloudCatcher project. Our Earth Observation research is greatly benefited by the contributions made by our volunteers, who are acknowledged below.

Past members

Many others have contributed to CloudCatcher. Here are some of our previous team members.

Eleanor

Eleanor was an intern who worked on the CloudCatcher project with the team. She focused on analysing the results from the first workflow, Catch that Cloud, and setting up the second workflow, You Cannot Be Cirrus, that will focus on cirrus cloud identification.

Hestia

Hestia was a work experience student who helped write some of our social media posts. She learnt how to search for and download the satellite images, and viewed using the satellite product software called SNAP Toolbox. Hestia made some really nice visuals that will hopefully encourage people to check out the project.

Finlay

Finlay was a work experience student who helped kick off the project. He did great work writing the code that is used to cut up the satellite images into smaller chunks that you will be classifying.

Mireya

Mireya was part of the team from the beginning of the project, and helped design some of the workflows.

We would also like to thank the Science and Technology Facilities Council for previously funding this work through a Spark Award and Innovation Bursary Fund.
