3 What is DAWBEE program? EUMETSAT information days in Ukraine and in Montenegro organized in 2009 showed great interest in receiving EUMETSAT data EUMETSAT initiative with the aim to provide operational satellite data and products of EUMETSAT to be accessible and upplicable in NMHS s of countries from western Balkan and eastern Europe including Caucasian countries EUMETCast reception stations containing all necessary software and hardware facilities for reception, processing and visualisation of products were established, deployed and installed in beneficiary countries Training workshops on satellite meteorology and on site training on station installation and maintenance were provided to local forecasters and operators 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 2

5 Significant DAWBEE issues Definition of standard EUMETCast reception station Selection of available application software Procurement of necessary hardware / software First installation, training of trainees / experts Common training for users Shipment, local installation and local training for users 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 4

6 Selection of available application software This issue was linked with selected OS (Windows/Linux Windows was preferred) As implication three possibilities were considered: 1. David Taylor (MSG data manager and Animator) (only for Windows) 2. SHMU software MSGProc & ViewMSG (available for Linux & Windows) 3. SUMO software (only for Windows) All three software packages were tested by experts from Bulgaria, Ukraine and Slovakia Finally the software of SHMU was selected to be installed on DAWBEE EUMETCast stations and used for processing and visualisation of MSG SEVIRI image data and MPEF products Compared aspects: Supporting EUMETCast data in general; calibration; corrections; RGB precalculations; set of RGB products; visualisation; product distribution; availability; functionality; performance and possible future development and support 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 5

7 Technical aspects of DAWBEE stations allowing access to all data disseminated through EUMETCast Europe channel robustness: fully redundant station with uninterrupted power supply simplified maintenance thanks to a single generic platform (Windows versus Linux OS were considered) simplified extension of the system to other hardware platforms no special IT knowledge for the users antenna procured and installed by the local meteorological service Main EUMETCast software components: Technisat DVB driver and application; EKU software; Tellicast client Operational software components: MSGProc, ViewMSGProc Operational software requirements: simple switching into different operational modes nominal, degraded; fully automatic processing and visualisation of data stream 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 6

8 Operational software more details To receive in real time all available EUMETCast data channels To process in real time MSG essential and/or MSG RSS image data To process in real time selected MPEF products To visualise and animate all processed data with simple control by user Low effort software maintenance, settings, data and products management What is missing: current software set is not capable to work with polar satellite data Unalterable geographical projection and impossibility to overlay processed data with external data sources 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 7

9 MSGProc as processing tool for MSG SEVIRI HRIT data Real time automatic processing of selected HRIT data stream (essential - 15 minute or RSS - 5 minute data) Real time automatic processing of selected MPEF data Temporary data in single binary format available to user for their own experiments RGB imagery as a result of processing 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 8

11 Feedback from users of DAWBEE stations In prevalent number of cases there were no problems with installation, training and initial use of stations in benefitial NMHS s In few cases there were requirements to add special features to processing and visualisation software Server and client are not in the same network Updating the graphics (lakes, Caspian sea) Few problems with stability and improper settings of processing software, fixed in consultation process with DAWBEE experts 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 10

12 New features and possible updates of application software for DAWBEE users Change from constant to flexible map scale (enable users to select appropriate scale from full Earth disc to synoptic, meso-synoptic up to nowcasting scale) Additional product projection regular longitude, latitude grid (enable users to use products in more easier way in other viewers like Google TM Earth, to overlay with other meteorological data) Improved image navigation and georeferencing in the latest version Integrated special tool Sun tag to measure cloud top height in visible imagery close to Sun terminator (high Sun zenith angle) useful to detect overshooting tops over thunderstorms Improved calibration on Sun height close to terminator thanks to improved image navigation 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 11

13 New ViewMSGProc features: ViewMSGProc program contains now new function - tool to estimate cloud top height using Sun elevation and cloud shadows length measuring tool in VIS MSG imagery 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 12

14 MSG HRV, :45 UTC Clouds over Algeria displayed by ViewMSGProc program Clouds and their shadows are visible and well delimited. Mean elevation of Earth surface above the sea is about 200m. User can interactively (by mouse pointer) track the direction of Sun illumination (azimuth and elevation) for every image pixel 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 13

15 Use the tool for estimation of cloud top height: 1. Set the pointer (red cross) at the edge of shadow 2. Set elevation of the Earth surface above the sea level (Pointer elevation [m]) 3. Set Sun azimuth s pointer length (yellow tag) to be at the edge of the cloud (Pointer length [pix]) 4. Program automatically will calculate horizontal length of pointer (Pointer length [km]) and using Sun elevation will estimate the cloud top (Target height [m]) 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 14

34 The most important technical/software issues from users How to update/re-install processing software? How to plot/add additional/subsidiary boundaries into image products? How to transfer products from processing to visualising computer using ftp? How to do complete backup of DAWBEE stations? How to save and restore application software settings? The most important issues from users concerning data and products What RGB products are better to use during the day and during the night? Is it possible to process in paralell 15 (essential) and 5 minutes (RSS) data? Why some MPEF products are not implemented? Why some MPEF products are not available every 15 minutes? How to modify RGB product? How to create new RGB product? Is any possibility to use RGB products together with other meteorogical data? 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 33

35 Conclusions DAWBEE stations were installed and are successfully operated in 11 NMHS s in Balkan, eastern Europe and Caucasian countries Current set of EUMETCast data which can be received and visualised brought new opportunities to users in weather analyses and forecasting Additional meteorological trainings for users in future can significantly enhance data and product usage (EUMeTrain, Eumetcal, EUMETSAT courses,...) Additional application software/updates of existing software for processing, visualisation and integration with non-satellite meteorological data can also enhance the utilization of available EUMETCast data Both online and classroom training events are recommended by DAWBEE experts in future Initiative from all DAWBEE users can play important role in this process 2011 EUMETSAT Meteorological Satellite Conference, 5-9 September 2011, Oslo, Norway 34
