  9. Products: Clouds Products • Cloud Mask (Cma) Provide information on the possible occurrence of clouds within each pixel. The central aim is to delineate all absolutely cloud-free pixels in a satellite scene with a high degree of confidence • Cloud Type (CT) The main objective of this product is to support detailed cloud analysis • Cloud Top Temperature & Height (CTTH) Contains information on the cloud top temperature and height for all pixels identified as cloudy in the satellite scene with the highest possible spatial and temporal resolution The EUMETSAT SAF on Nowcasting & VSRF

  10. Products: Precipitation Products • Precipitating Clouds (Pc) Provides information on the probability of weak, moderate and strong precipitation • Convective Rainfall Rate (CRR) Provides the maximum level of information on convective rainfall from the SEVIRI channels The EUMETSAT SAF on Nowcasting & VSRF

  11. Products: Precipitation Clouds PC Based on SMHI’s long experience on precipitating cloud products As output of the SCANDIA cloud classification scheme Stadistical scheme making use of IR/VIS channel and forcing parameters from the NWP data Channels used: VIS 0.6, VIS 0.8, NIR 1.6, IR 3.9, IR 10.8, IR 1.0 Scientific Report on www.inm.es/wwg and www.smhi.se The EUMETSAT SAF on Nowcasting & VSRF

  12. Products: Convective Rainfall Rate CRR Based on RAINSAT methodology statistical relationship between satellite (multi-band imagery) and rainfall rate data obtained using radar data. CRR value for each pixel is obtained from calibration matrices. Calibration matrices are different if a pixel belongs to day or night mask. Day pixels CRR calibration data is a matrix 3-D (bands: IR10.8, WV6.2, VIS0.6.) Night pixels calibration values are stored in a 2-D matrix (bands: IR10.8, WV6.2.) Normalised visible counts are obtained using Binder algorithm. Smoothing process performed to eliminate stratiform rain data -not associated with convective clouds. The obtained CRR significant data are set to zero if all the nearest pixels in a box of 14x14 do not have an equal or higher value than 3mm/h. The EUMETSAT SAF on Nowcasting & VSRF

  13. Products: Convective Rainfall Rate CRR • The “RAINSAT” output is used as the input to the Auto-estimator algorithm proccess, • This included adjusdtements by • humidity: TPW x HR • Orography • Clod top area evolution • Cloud top gradient • Etc The EUMETSAT SAF on Nowcasting & VSRF

  14. Products: Clear Air Mass Products • Total Precipitable Water (TPW) Total atmospheric water vapour in a column of air extending from the Earth's surface to the "top" of the atmosphere • Layer Precipitable Water (LPW) Atmospheric water vapour contained in a vertical column of unit cross-sectional area in three layers in the troposphere • Stability Air Imagery LI index summarising the information of the SEVIRI channels • Air Mass Analysis Evaluates basic quantities that describe air masses (upper and middle level humidity, mean temperature, atmospheric stability, cloud pattern, etc) and to combine them into one integrated classification of the air mass The EUMETSAT SAF on Nowcasting & VSRF

  15. Products: Winds and Conceptual Model Products • High Resolution Wind (HRW) Provides information on mesoscale wind vectors using data from the HRVIS channel at two spatial resolution: 25 and 10 km. • Rapid Development Thunderstorm (RDT) Twofold objectives: identification, monitoring and tracking of intense convective systems, and detection of rapidly developing convective cells • Automated Satellite Interpretation Imagery (ASII) Provides an automatic interpretation of features seen on satellite images. Hence, the product identifies fronts, wave structures, areas of intensification at fronts by jet streak crossing, position of the jet axis, comma clouds, enhanced convection areas, etc. The EUMETSAT SAF on Nowcasting & VSRF
