Description of the main changes

GLOBO

(operational from for realtime forecasts in S2S archive)

  • The lagged ensemble configuration is changed: 
    • it now uses
      • 10 perturbed initial conditions every 6 hours, taken on Wednesday at 06, 12, 18Z respectively and on Thursday at 00Z (with control run on Thursday at 00Z)
    • instead of former
      • 10 perturbed initial conditions every 6 hours, taken on Wednesday at 00, 06, 12, 18Z respectively (with control run on Thrusday at 00Z)
  • The time range is extended from 32 to 35 days
  • The output frequency for 10u/v parameters is increased from 24- to 6-hourly
