The article highlights a collaborative effort led by UC Santa Barbara, in partnership with FEWS NET and UCAR’s COMET program, to rebuild and expand weather observation networks in Southern Africa. By deploying low-cost 3D-Printed Automatic Weather Stations (3D-PAWS) in Malawi, Zimbabwe, and Madagascar, researchers aim to deliver real-time measurements of rainfall, temperature, and humidity.
These measurements complement satellite data to improve forecasts, disaster preparedness, and food-security planning.
A regional effort to rebuild meteorological capacity
In Southern Africa, a concerted partnership is working to restore and advance meteorological services where data gaps threaten forecast accuracy and community resilience. The Enhancing Meteorological Networks Partnership focuses on creating sustainable, locally owned observation networks by enabling national agencies to fabricate, install, and maintain their own stations.
The goal is to restore robust data streams needed for reliable rainfall estimates, flood warnings, and agricultural planning.
What are 3D-PAWS and how they work
The project centers on low-cost 3D-Printed Automatic Weather Stations (3D-PAWS), which provide ground-based observations of key atmospheric variables. These stations collect rainfall, temperature, and relative humidity, along with other measurements critical for weather forecasting.
By placing these stations in regions currently underserved by traditional networks, the program creates a more complete picture of local climate conditions. Ground measurements from 3D-PAWS complement satellite observations, enabling more accurate forecasts and more timely warnings before weather hazards escalate.
This approach helps reconcile discrepancies between satellite estimates and on-the-ground realities, improving both short-term forecasts and longer-term climate analyses.
The 3D-PAWS approach is designed to be affordable, rapid to deploy, and locally maintainable. By enabling end-to-end fabrication within the country, national meteorological services gain ownership over hardware and knowledge.
This supports faster repairs and ongoing sustainability even in resource-limited settings.
- Cost-effective scalability—distributing a larger number of stations without prohibitive expenses.
- Real-time data—providing timely measurements essential for immediate decision-making.
- Local capacity building—training and empowering local technicians to install, calibrate, and repair equipment.
- Improved data fusion—integrating ground-based observations with satellite data for better forecasts.
- Strengthened early warning—supporting evidence-based alerts for communities facing flood or drought risks.
Why restoring networks matters for climate resilience
Across parts of Africa, the number of functioning weather stations has declined, leading to gaps in reliable rainfall measurements and other essential observations. The partnership emphasizes that timely, trusted rainfall data are crucial for community decisions about planting, irrigation, and flood preparedness.
UC Santa Barbara’s Climate Hazards Center underscores that accurate rainfall observations are a cornerstone of both agricultural planning and disaster risk management.
From data to action: agricultural forecasting and food security
When communities have access to robust, ground-truth rainfall data, farmers can choose optimal planting windows, adjust crop calendars, and optimize irrigation strategies. Enhanced observations also improve regional agricultural forecasts, informing policy makers and aid organizations about potential food-security risks and the allocation of resources ahead of droughts or floods.
This local ownership of data streams fosters more resilient food systems, reducing vulnerability to climate variability.
Towards sustainable, locally governed meteorological networks
The initiative demonstrates how 3D printing and open-access hardware can transform meteorological services in low-resource settings.
By combining affordable technology and community-based operation, the project aims to establish enduring networks.
This approach empowers Malawi, Zimbabwe, and Madagascar to forecast weather with greater confidence and protect vulnerable populations.
It also supports sustainable agricultural development.
