1. 12/03/041 Remote sensing in Weather applications We produce algorithms and prototypes of products for FMI forecasters and customers. Our tools include –satellites –weather radars –lightning detection systems –extrapolation, nowcasting and mesoscale analysis

2. 12/03/042 Winters in Finland are dark and cold - the sun elevation is low also daytime. This is one of the challenges to satellite meteorology (SEVIRI, AVHRR, MODIS, MERIS...) Network of 7 modern radars gives the best estimate of precipitation

3. 12/03/043 FMI is active in international satellite research, development and education programs Research and development is oriented in providing tools for operational weather service –Mesoscale meteorology –For snow ploughing, forest fires, floods

4. 12/03/044 FMI Satellite Activities International activities in EUMETSAT, ESA, NOAA, EUMETNET and WMO Nordic co-operation; NOSC, NOMEK Using instruments on both polar and geostationary satellites (AVHRR, SEVIRI, MODIS, MERIS...) Research focus: clouds, fog, low cloud, extreme weather (convection)

5. 12/03/045 Satellite data reception In Helsinki NOAA series Meteosat-7 Meteosat-8 In Sodankylä EOS/Terra, Aqua Future METOP

6. 12/03/046 7 radars cover most of the country own maintenance data availability 99.4%

7. 12/03/047 Advanced applications Improved quality of accumulation –adjustment for snow/rain/mix –correction for vertical reflectivity profile Target identification –hail –non-meteorological echoes Nowcasting of precipitation

8. 12/03/048 Lightning location Ground lightning location system: present model in operational use since 1998 Example: intense day May 26, 2003 5 sensors in Finland, several connected from Scandinavia Cloud lightning location system in SW (3 sensors) in test use
