How can I see the available dates for a set of data?
The available dates are shown beneath the dataset dropdown once you select a dataset
When will all Cryo2ice period data be available?
All data post the orbit alignment in July 2020 is available.
Will pre alignment data be available?
Yes - we are populating the IS2 and CS2 data back to the IS2 launch date in 2018
Will you add more products?
Yes - CryoVex is the next product we are adding. We are in discussions about adding other datasets such as CS2 back to 2010, IS2 ATL03 and other CryoTEMPOs
Can I request more products are added?
Yes - please email firstname.lastname@example.org with any suggestions
Will you add more features?
Yes - we are in discussions about extending the functionality such as adding support for n-dataset intersections.
Can I request additional features or enhancements?
Yes, we'd love to get your input - please email email@example.com with any suggestions
Do I need any packages to run the Python download scripts?
No - it should work with a default Python 3 environment.
How do I use the KML file?
You can use the KML file to save the visualisation component of your results and view it at a later time. We recommend loading the file into Google Earth: https://earth.google.com/web/
What data does the CSV file contain?
The CSV file provides all the information necessary to retrieve intersecting data from your downloaded product files. This includes segment details such as start and end times, lat/long coordinates, and names of the product files for each result. Additional information about each segment's orbit track is also given. Finally, there is a segment ID value, which is also displayed in our visualisation component - this will help you refer between the two if needed.
What does the resolution dropdown mean?
Underlying the data is a grid - this makes the system fast. 10km and 5km are available resolutions. 10km is sufficient for most user cases and will mean that any data within 10km of each other will be classed as an intersection. Given the footprints of the satellites, this is sensible. Selecting 5km will be slower but give only observations within 5km of each other. In practice there is very little difference.
What coordinate system does the underlying grid use?
The EASE grid (2.0): https://nsidc.org/data/ease
