SMEX05 Meteorological Network Data for Iowa Watershed

Meteorological data was collected during the Soil Moisture Experiment 2005 (SMEX05) in the Walnut Creek watershed area of Iowa, USA. The dataset is provided by the National Snow and Ice Data Center (NSIDC) with documentation from the Principal Investigators. Sources conflict on the last updated date, reporting either 2005 or 2026.

Use Cases

• Analyzing relationships between soil moisture, precipitation, and atmospheric temperature using soil moisture, rain, and air temperature columns.
• Modeling surface energy fluxes by examining heat flux and photosynthetically active radiation measurements.
• Studying evapotranspiration processes with water vapor and evaporation data.
• Investigating wind patterns and their impact on local microclimate using surface winds data.
• Correlating soil hydraulic conductivity with precipitation events to understand watershed runoff.

Strengths

• Data originates from a focused field experiment (SMEX05) designed for soil moisture studies.
• Covers multiple atmospheric and land surface variables as indicated by detailed tags from datagov.
• Hosted and distributed by the authoritative NSIDC organization.

Limitations

• Documentation was provided solely by Principal Investigators and not reviewed by NSIDC, limiting support.
• Critical metadata conflicts: last updated date is reported as both 2005-07-17 and 2026-03 12.
• Specific row counts, file sizes, and exact column names are unavailable across all platforms.
