Eclipse Data Analysis
In addition to collecting data, we also encourage citizen scientists of all ages to try their hand at analyzing the data. Below you will find some example graphs from the data collected during the eclipse on August 21st, 2017 (click here to download graphs as a PDF) and tips and tricks for accessing the data. We will update this page with data from future eclipses as they occur.
Accessing the Data
There are two primary ways to access GLOBE data. The first is the GLOBE Visualization System, which allows you to add layers of data (for example, here's a link with clouds and air temperature layers from the eclipse on August 21st, 2017.) Tutorials are available in PDF and PowerPoint formats.
While the data visualization system system allows a quick view of the data, and some comparison between data sites using the multi-site plots tool (graph icon in the upper left menu), in order to do more detailed analysis, you will need to download the full data tables. There are two primary ways to do that.
- The first option is through the GLOBE Data Visualization system itself. Click on the expand options dots to the right of the layer you wish to download, select View Layer Table, then Export .csv in the window that pops up.
If you don't want the entire layer, it is also possible to subset the data by using the filters feature. You can filter by a place such as a state, country, or even proximity to a geographic feature such as a lake or a river. You can also choose a latitude/longitude range, or draw a shape on the map. Once you have selected your filter, follow the directions above to download the layer table.
2. The second option is the GLOBE Advanced Data Access Tool. This allows you to filter by more than one protocol at a time, as well as for a range of dates. ADAT can be powerful, but also may be less intuitive than starting from the map as described above, so choose the tool that is best for your purposes.
Eclipse 2017 Data
Because the eclipse is such a time-focused event, we have also been able to pull some data sets that might be useful for a variety of people, and could save time in accessing the data. Click here for a page with downloadable files of data from the August 21st, 2017 event.
