Online — Promoting its initiative to develop and deploy low-cost weather instrumentation globally, the University Corporation for Atmospheric Research (UCAR) will be at Meteorological Technology World Expo (09-11 October 2018) to demonstrate its 3D-printed automatic weather station (3D-PAWS), which can be used as a low-cost surface observation solution for less developed, data-sparse regions of the world.
The current design consists of a three-cup anemometer, wind vane, tipping bucket rain gauge and sensors for temperature, relative humidity, light and pressure.
The system is designed to be adapted and installed using locally sourced materials.
Sensor operation, communication and data archiving are controlled using a low-cost Raspberry Pi computer, which is installed in a waterproof housing on the instrumentation frame.
Power can be supplied using a 5 V input or through a battery with solar power backup.
Communications with the 3D-PAWS system are achieved with a direct network connection, wirelessly or through an adapter or GSM cell.
What is MetEd?
The MetEd website provides education and training resources to benefit the operational forecaster community, university atmospheric scientists and students, and anyone interested in learning more about meteorology, weather forecasting, and related geoscience topics. MetEd is populated and maintained by the COMET® Program, which is part of the University Corporation for Atmospheric Research’s (UCAR’s) Community Programs (UCP). The MetEd website is made possible by the sponsors of the COMET® Program.
