Monitoring of the observing system Surface observations are monitored on the national level, upper-air observations are monitored on the regional level. 7. Forecasting system We have no NWP model of our own. Neither we originate any medium - range weather forecasts. Only weather trend outlooks for the 4th or the 5th day are being issued. Short - range (1 - 3 days) weather forecasts are originated manually using HIRLAM (0 - 36 h data), GM & EM (via FAX-E satellite receiving station). These forecasts are issued once a day with additional updates in case of need. 8. Verification of prognostic products N/A 9. Plans for the future To put into operation a workstation version of the HIRLAM model with a domain over the Baltic states.
