Finished! Looks like this project is out of data at the moment!
Fantastic job, everyone! You have now completed a big chunk of data, and we will spend some time looking into all the temperature time series and improving the workflows based on your comments and questions. Thank you so much for all your help! We will be back with more tasks later this fall.

30 May 2024: First quality-controlled data batch
Hey everyone,
First, thank you very much for the sustained effort to digitize all this data. More than 1200 volunteers have joined the project over the past two months, and more than 500 pages are classified every day - by you!
The second batch of data from Greenlandic stations is almost completely digitized now. In the past weeks, I have processed all the data, checked for disagreements, cleaned up formatting, and put everything together.
This means that not only do we have detailed information about the temperatures. We now also know much more about where each instrument on the stations was, who made the observations, and details about temporary changes to the measurement routines.
Daily temperature measurements (hours 08, 14, 21)
Most of the data is on a daily resolution with measurements in the morning, midday, and late evening. Most of the measurements were from 8 a.m., 2 p.m., and 9 p.m., which are also the names of the workflows. In the following chart, all this data is to make a chart of the temperatures. This means that we can now go back to the late 1800s and see the temperature on a specific day in Nuuk (Godthaab) or Tasiilaq (Angmagssalik):
There are big differences in temperatures (e.g., from -20 to +20 degrees), so it can be hard to see the trends in data. Later, I will try to see if I can show the data in another way, so you can zoom in on specific time intervals in the dataset.
Monthly temperature measurements (hours 08, 14, 21)
Many stations don't have as high temporal resolution as the time series from Godthaab and Angmagssalik. Still, with your effort, we have gained much more knowledge of the general weather and climate in other parts of Greenland, which will improve many of our station time series:
Cheers,
Johan

9 April 2024: One week since launch!
Hey everyone,
Thanks for joining this project! It has been a week, and we are making great progress through this first batch of data!
Right now, we have more than 850 volunteers onboard. Together, you have digitized nearly 3,000 pages of temperature records and metadata from 10 weather stations in Greenland. Fantastic job!
Also, thanks for the questions and feedback on the talk pages. It's much appreciated, and I will try to improve the task descriptions continuously.
I've done some initial processing on the data from the "Temperature, 8 a.m. workflow", and I have three charts to show our progress. Each dot represents a data point typed in by one of you over the past week. We will iron out outliers and odd-looking data later during the quality control phase.
As for the metadata, it is tricky to display that in a chart, but there is a lot of important information there. It will come in handy when we dive deeper into the data.
Keep it up, volunteers! We are on the right track.
Cheers, Johan
