SMAPVEX19-22 Lidar Elevation Model for Petersham, MA in 2022

April and August 2022 ground surface elevations derived from lidar measurements collected near Petersham, Massachusetts. These data were gathered during the SMAPVEX19-22 campaign to validate satellite-derived soil moisture estimates in forested areas. The two acquisition periods characterize differences during 'leaf-off' and 'leaf-on' conditions.

Use Cases

• Validate satellite-derived soil moisture estimates based on ground surface elevation data.
• Analyze terrain changes between leaf-off and leaf-on seasons based on the two acquisition periods.
• Model hydrological processes in forested areas based on high-resolution elevation data.
• Assess the impact of vegetation phenology on remote sensing measurements based on the campaign's stated aim.

Strengths

• Data collection occurred during two distinct seasons (April and August 2022) to capture leaf-off and leaf-on conditions.
• Focus on a specific, well-defined location (vicinity of Petersham, MA) with forested land cover.
• Data is associated with a specific scientific campaign (SMAPVEX19-22) aimed at soil moisture validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
