Real-time Water Vapor Sensing with Suominet -- Today and Tomorrow

Recent Ground Based GPS Meteorology Developments for SuomiNet

Over the past 10 years significant progress has been made in atmospheric sensing with GPS. Both spacebased atmospheric sounding and ground-based measurements of integrated delay due to the troposphere have shown promise for meteorological applications. Now the focus is shifting from developing and validating the sensing technology towards applying it to weather forecasting. This paper will focu...

SuomiNet: A Real-Time National GPS Network for Atmospheric Research and Education

We propose to develop “SuomiNet”, a universitybased, real-time, national Global Positioning System (GPS) network for atmospheric research and education. The proposed network, named to honor meteorological satellite pioneer Verner Suomi, will exploit the recently-shown ability of ground-based GPS receivers to make thousands of accurate upper and lower atmospheric measurements per day. SuomiNet’s...

Real-time GPS sensing of atmospheric water vapor: Precise point positioning with orbit, clock, and phase delay corrections

The recent development of the International Global Navigation Satellite Systems Service Real-Time Pilot Project and the enormous progress in precise point positioning (PPP) techniques provide a promising opportunity for real-time determination of IntegratedWater Vapor (IWV) using GPS ground networks for various geodetic and meteorological applications. In this study, we develop a new real-time ...

Improving Gas Sensing Properties of Tin Oxide Nanowires Palladium-Coated Using a Low Cost Technique

Thin films of SnO2 nanowires were successfully prepared by using chemical vapor deposition (CVD) process on quartz substrates. Afterwards, a thin  layer of palladium (Pd) as a catalyst was coated on top of nanowires. For the deposition of Pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors...
