Show moreThe atmospheric limb sounding technique based on the Global Positioning System (GPS) has been shown to be accurate and of very high vertical resolution. The fact that the GPS radio occultation (RO) technique is not affected by clouds or precipitation, has no instrument drift, and requires no calibration makes it ideally suited for climate monitoring and global weather prediction. The ROCSAT-3/COSMIC constellation will be launched in late 2005, and will provide ~3,000 GPS radio occultation soundings per day to support operational weather prediction, climate analysis , and ionospheric research. The EQUARS mission, to be launched in 2006, will add ~500 soundings in addition to ROCSAT-3/COSMIC. In this paper, we review selected GPS RO studies that are relevant to weather prediction and climate analysis. Show less
