Density of Drifting Buoys in 50X50 Grid
Observations Density of Drifting Buoys in 50X50 Grid
Based on expected number of obs. per buoy per months =(24*30)=720 observations

GTS Data delivery format
• As of July 2016
– Almost 100 % drifting buoys provide data to the GTS in BUFR format (one drifter reports only in TAC)
– 34 % of moored buoys (Tropical and Coastal/National MB) provide data to the GTS in BUFR format
