3rd European Nowcasting Conference
24-26 April 2019
AEMET, Madrid
The third European Nowcasting Conference took place in Madrid from 24 to 26 April 2019, and was attended by around 100 participants from 22 countries (Austria, Belgium, Bulgaria, Croatia, Czech Republic, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Republic of Korea, Russia, Singapore, Slovenia, Spain, Switzerland, United Kingdom, United States), representing National Meteorological and Hydrological Services, universities/research institutes and the commercial sector. They presented their latest findings on observations, seamless prediction, nowcasting techniques and systems, verification and user aspects. Different methods of warning procedures were presented, the potential of artificial neural networks was examined (e.g. concerning the evolution of thunderstorms), and new approaches for forecast uncertainty estimates were investigated. Besides the many excellent presentations, there was room for discussions during dedicated time slots at the end of each session and during poster sessions.

This animation shows the weather and surface marine observations over the Europe-Atlantic area for the year 2018.
Each of the 24 frames per second shows, for a given date and hour, contours of 6-hour averages of mean-sea-level pressure from ERA5 (generated using Copernicus Climate Change Service information 2019), as well as locations of all observations from buoys or ships or fixed platforms received within +/- 12 hours.

During the weekend of 26-27 January 2019, a deep cyclone passed across British Isles and Ireland, over the North Sea and into central Europe. It caused severe winds across the British Isles, Ireland, parts of France, BeNeLux and France. This OPERA animation shows the showers and precipitation bands.
Please find below the announcement for the Summer Course “Advanced Aerobiology 2019“.
The registration deadline has been extended to the 22nd March.
The third European Nowcasting Conference (ENC) is organised under the umbrella of the EUMETNET Nowcasting Programme and will be held at the headquarters of AEMET in Madrid from 24 to 26 April 2019. The goal of the conference is to promote recent advances in the theory and practice of nowcasting in Europe and other parts of the world. The conference welcomes participants from operational, research and forecast user communities to discuss methods for improving the quality of nowcasting in Europe. The scientific program will feature keynote addresses as well as contributed presentations and offer room for discussions.

2nd European Nowcasting Conference
3-5 May 2017
DWD, Offenbach
The 2nd European Nowcasting Conference (ENC), organised under the umbrella of the EUMETNET nowcasting project ASIST, was held at the headquarters of DWD in Offenbach, Germany, from 3 to 5 May 2017. Close to 100 participants from 24 nations presented their latest findings on observations, nowcasting techniques, verification, user aspect and combined nowcasting/numerical weather prediction. Besides the many excellent presentations, there was plenty of room for discussions during dedicated time slots at the end of each session as well as during poster sessions and coffee breaks.
To a large extent, observation and nowcasting techniques dedicated to convective phenomena were presented, indicating that thunderstorms and lightning are still one of the major themes in nowcasting. Furthermore, it could be noted that, even at individual national meteorological services (NMS), a wide variety of nowcasting systems and models are available which can lead to an overwhelming (and sometimes inconsistent) suit of nowcasting information available for forecasters. It is thus not surprising, that efforts towards seamless prediction systems, incorporating a multitude of nowcasting and NWP models, can be noted. While nowcasting is still tied to observations and their short-term extrapolation, the combination of nowcasting with NWP is gaining momentum as NWP systems with rapid update cycling are approaching the nowcasting domain.
While the conference gave an impressive view of the many efforts in nowcasting techniques, there currently still seems to be a lack of coordinated activities. Similar systems are developed in parallel at different research institutes or NMS’s and one might ask if a coordination of those efforts could be fruitful and result in widely accepted and applied nowcasting tools. Modelling consortia, such as those for NWP’s, are not yet existent for nowcasting. Possibly, such cooperation is difficult due to regional and observation specific characteristics as well as the end-user focused nature of nowcast-ing . In this heterogeneous and interdisciplinary setting, it is important that the EUMETNET nowcasting project ASIST continues to support the cooperation between nowcasting researchers and practitioners among NMS’s.

OPERA Data production
During the previous OPERA phase (2019-2023), the data centre (ODYSSEY) was gradually replaced with three new production lines (CUMULUS/STRATUS CIRRUS, and NIMBUS).
New production lines
• CUMULUS/STRATUS, a real-time data hub providing the incoming data back to members in approximately real-time for their own processing (e.g. regional composites or NWP assimilation) and to the other two production lines (CIRRUS and NIMBUS). The production line has been operational since Q2/2021.
• CIRRUS producing 5-minute instantaneous maximum reflectivity composite (dBZ) for current weather, severe weather alerts and aviation needs. It is replacing the ODYSSEY maximum reflectivity composite with improved spatial (now with 1 km gridding) and temporal resolution (from 15 – minutes to 5- minutes). The production has been operational since Q1/2024. Documentation regarding the CIRRUS maximum reflectivity product and its differences compared to the ODYSSEY maximum reflectivity product can be found here.

• NIMBUS produces centrally the quality-controlled products; instantaneous rain rate (mm/h) and 1 – hour accumulation (mm) composites, and wind profiles (TBD Q4/2024), and additionally the quality-controlled volume data for NWP assimilation. It replaces the ODYSSEY production for the above-mentioned products. The NIMBUS production has been operational since Q2/2024. Documentation regarding the NIMBUS composites and their differences compared to the corresponding ODYSSEY can be found here:
