MIDAS is a collaborative project between The Portuguese Institute for Sea and Atmosphere (IPMA) and The Royal Netherlands Meteorological Institute (KNMI) that aims to provide EUMETSAT users and the NWP community with relevant information on the use of scatterometers in data assimilation.
The main objectives of the study are to:
Through the benefits in regional mesoscale NWP, optimal use of scatterometer winds will benefit marine alert advisories in the off-shore economy (transport, energy, tourism). In addition, it will provide improved high-resolution winds to force ocean, wave and surge models. Moreover, lessons learned from this study may contribute to the future transition to Metop-SG.
IPMA and KNMI will conduct this study using the HARMONIE-AROME 4D-Var DA system for a domain over southwestern Europe. See the detailed description of the HARMONIE-AROME forecast model setup.
The domain includes a large area covered by the Atlantic where initialization through observations, such as ocean winds from scatterometers, is critical. A 4D-Var DA method will allow to overcome the time mismatch between observations and analysis time, which is a major limitation of scatterometer winds assimilation in current mesoscale convective scale NWP models using the 3D-Var technique.
Specifically, the study will address:
