Assimilation of CHAMP RO dtaa John de Vries (jdevries@knmi.nl) • CHAMP: CHAllenging Mini-satellite Payload • GPS radio-occultation receiver • Fig. A: 4 to 15 per HIRLAM analysis cycle/area • 45 m (@ 500hPa) to 60 m (@ 10 hPa) resolution • Fig. B: Only above 1 to 2 km (mid-latitudes) • Refractivity translates into T, q, p • Fig. C: rms and bias • HIRLAM • Impact study over 1 month • Var QC? • Largely neutral (better bias, same RMS, so more stdev)
Lead Centre on Verification methods • Bologna meeting: coordination of PEPS/verification • Bayesian Model Averaging • Workshop on Verification Methods • in particular for probabilistic forecasts(?) • 15-17 May 2006 (?)
