A time series from 2016 to 2022 contains snow depth maps and digital elevation models for Grand Mesa and Banded Peak Ranch, Colorado. The maps are derived from very-high-resolution satellite stereo images and lidar point cloud data, with two maps coinciding with the 2017 NASA SnowEx field campaign. The dataset is provided by NSIDC_CPRD.
Use Cases
- Validate satellite-derived snow depth estimates based on coinciding in-situ measurements from the 2017 field campaign.
- Analyze temporal changes in snow depth over a multi-year period based on the annual time series.
- Generate or refine digital elevation models for mountainous terrain based on the snow-on and snow-off DEMs.
- Compare snow depth estimation methods based on data from multiple satellite platforms (WorldView-2, WorldView-3, Pléiades-HR).
Strengths
- Provides a multi-year time series of snow depth maps spanning from 2016 to 2022.
- Includes data from multiple high-resolution satellite platforms (WorldView-2, WorldView-3, Pléiades-HR) and lidar.
- Two snow depth maps coincide temporally with the 2017 NASA SnowEx Grand Mesa field campaign, enabling validation.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to nasa_earthdata, focusing on two specific Colorado areas.
