ASIST – Application oriented analysis and very short range forecast environment – started in July 2015 to set up a European wide cooperation on nowcasting and very short range forecasting (VSRF). It is the follow-up project of the Nowcasting Activity 1st phase. The principal objectives are to:
The ASIST project aims to provide a platform for NMHS’s which enhances the capabilities of each individual member by facilitating concerted approaches to tackle the challenges in nowcasting and VSRF. The principal goals can thus be summarized as the exchange of knowledge and experience, coordination of research and development, evaluation and training among members that are active in the development and operation of nowcasting and VSRF systems. Furthermore, information exchange with other groups and programmes such as the EUMETNET Observation Programme, SRNWP-EPS of the EUMETNET Forecasting Programme, WMO nowcasting research working group, EUMETSAT SAF’s and others, will be encouraged and carried out.

Summary of 2nd European Nowcasting Conference
3-5 May 2017
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 nowcasting . 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.
