Monitoring Snow Cover Patterns and Seasonality

Challenge Description

Information on snow cover extent is a key component of seasonal monitoring and food security early warning in WFP operations for Central Asia. Agricultural production in countries like Afghanistan is crucially dependent on snow accumulation and snowmelt release from February onwards. Detecting major deficits in snow extent can provide timely indications of potential shortfalls of crop production. Access to historical data may also flag areas where there may be long term tendencies in snow cover that are relevant for government and humanitarian agency longer-term planning.

For these areas, the outputs of this pipeline will articulate with those that produce vegetation index parameters, so that impacts of snow cover variations can be validated against the behavior of vegetation related information over crop-producing regions.

Results

The results below are divided into Software Repositories, Online Services and Data Products Repositories.
In case you would like to get in touch with us about specific results, please use the indicated reference codes (e.g. WFP-01-01-01).

Software Repositories

There are two categories of software repositories generated for the Challenge:

• GitLab repositories are hosting the reference software code, for use by the team members of a challenge only (restricted access)
• GitHub repositories are hosting the public software code (mirrors), for engagement and collaborative work with the broad community of software developers (public access)

Follow the links below to proceed to one or the other, and find an "Ellip Workflows (ewf)" software application implementing a data processing function.
You can adapt this software to your own context, commit a contribution to the related repository, or engage with the BETTER consortium to run it for a specific purpose (new area of interest, ...) by requesting Cloud resources to support (at) terradue.com

Data Processing as-a-Service

There are two categories of "Data Processing as-a-Service" application packages created for the Data Challenge:

• Data Processing Pipelines are controlling full EO data production campaigns, for use by approved members of a challenge only (authorized access),
• On-demand Processing Services are controlling individual EO data processing jobs, also for use by the approved members of a challenge only (authorized access).

Follow the links below to proceed to one or the other, via a dedicated Geobrowser application providing web access to one or the other of the Data Processing services.
You can engage with the BETTER consortium to request authorized access via support (at) terradue.com

Data Product Repositories

There is a dedicated client App publicly available for the visualization of the data products resulting from EO data processing challenges.

The results can consist of:

• Validation data: small amount of data products generated for approval by the Challenge promoter
• Production campaign data: full-time series/collection of data products answering the Challenge promoter question about Earth Observation data being used to help solve global societal challenges
