Seasonal Fractional Snow-Covered Area Algorithm Source Code

Fortran 90 source code for computing seasonal fractional snow-covered area. The algorithm reads snow depth and snow water equivalent data from an example file and outputs fractional snow-covered area values. The code is hosted by ENVIDAT and was last updated in January 2021.

Use Cases

• Calculate fractional snow-covered area based on snow depth and snow water equivalent data
• Integrate snow cover algorithms into hydrological or climate models
• Validate satellite-derived snow cover estimates using ground-based snow data

Strengths

• The algorithm is implemented in Fortran 90, a language commonly used in scientific computing
• Includes an example input file (HS_SWE.txt) demonstrating data format and usage

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Last updated 2021-01-01 00:00:00; freshness should be verified
• Column-level documentation is absent; field semantics must be inferred after download
