Daily Soil Moisture Estimates from Neutron Probes in Bahia, Brazil

Soil moisture data contains daily averages of volumetric water content from prototype cosmic ray neutron sensors. Measurements were taken hourly at a centre-pivot irrigation site in Bahia, Brazil, between June and December 2023 to study data-driven irrigation optimization.

Use Cases

• Model daily volumetric water content averages to optimize centre-pivot irrigation schedules
• Analyze corrected soil moisture estimates for environmental effect patterns across the 2023 measurement period
• Validate prototype cosmic ray sensor performance for distributed soil moisture monitoring in agricultural settings

Strengths

• Data includes corrected daily averages of volumetric water content for improved accuracy
• Hourly measurements provide high temporal resolution for a seven-month period in 2023
• Focus on a specific centre-pivot irrigation site in Bahia, Brazil, offers localized agricultural insights

Limitations

• Unknown sample size and row count limit assessment of statistical power
• Geographic scope is limited to a single site in Brazil, reducing generalizability
• Data from prototype sensors may require validation against established measurement methods
