RAOB Problems After 1998 RAOB Problems After 1998 • Statistics: 1999: 4-7 sondes per day p y • 2000: 10-12 sondes per day • • 2001: 16-19 sondes per day 2001: 16 19 sondes per day • 2002: 22-24 sondes per day • BUT : main problem is absence of regularity: • 1999 : only 2 stations provided daily regular data y p y g • 2002 : only 15 stations provided daily regular data data
