SMAPVEX19-22: Soil Moisture and Temperature Network at Millbrook

25 temporary stations recorded soil moisture, soil temperature, and air temperature measurements across a 30 by 40 km domain near Millbrook, New York. The network was installed in May 2019 for the SMAPVEX19-22 campaign, with data collection projected to continue through 2022. This dataset supports the calibration and validation of satellite-based soil moisture observations.

Use Cases

• Validating satellite-derived soil moisture products from missions like SMAP based on in-situ sensor measurements.
• Analyzing the spatial and temporal correlation between soil moisture, soil temperature, and air temperature across a field site.
• Supporting land surface and hydrological model development with time-series data from a distributed sensor network.

Strengths

• Provides measurements from a network of 25 spatially distributed stations, enabling analysis of variability across a 30x40 km area.
• Covers a multi-year time series from May 2019, with planned operation through 2022, supporting longitudinal study.
• Dataset is associated with a NASA field campaign (SMAPVEX), indicating a structured scientific purpose.

Limitations

• Column names and specific data formats are not provided in the available metadata, limiting immediate usability.
• Conflicting 'last updated' dates (2026 vs. 2021) across platforms create uncertainty about data currency and completeness.
• The dataset's current coverage is stated as through 2021, with 2022 data only projected, indicating it may be incomplete for its intended temporal scope.
