COSMO Data Assimilation. Applications for Romanian Territory

In the context of numerical weather prediction, the requirements for a data assimilationsystem are dependent on the purpose and main characteristics of the numerical model for which they are used as initial conditions. The COSMOmodel in operational configuration is characterized by high resolution on a limited domain, with the main purpose of producing accurate short period numerical weather forecasts. One of the main concerns in improving the quality of numerical weather forecastsis the development of data assimilationtechniques and proper usage of various types of observation data.
