What I do Dr. Najafi research is centered on hydroclimate variability and predictability at short, medium-range, and sub-seasonal to seasonal time scales. He has developed a real-time soil moisture drought forecasting system in Germany (HS2S ) providing soil moisture outlooks four the next four calendar weeks. The system has become operational since January 2021. In addition, Dr. Najafi is investigating the devastating 2021 summer flood in Ahr Valley by skill assessment of UFZ state-of-the-art horological forecasting system. Before joining UFZ, he has contributed in policy advice pertinent to water resources management in semi-arid regions in Southwest Asia.

Modular Observation Solution for Earth Systems (MOSES) Novel observing systems will improve understanding of the complex interactions across scales and Earth compartments. My research is part of the MOSES project , a joint facility in the research field “Earth and Environment” proposed and implemented by the Helmholtz Centres.
Online forecast information out of my research will provide information for conducting new event-oriented observation campaigns and contributing to progress in Earth observation. Forecast information of weekly precipitation, maximum air-temperature and soil moisture over Germany contributed to MOSES by UFZ will be disseminated online via the HS2S weblink.

Oct 12, 2022 Dr. Husain Najafi won the UFZ Young Scientist Award for Applied Research 2022. The award goes to him for his excellence and dedication in development of the operational drought forecasting system in Germany and investigation of 2021 summer flood predictability. Hydrological forecasting systems are the fundamental component of early warning systems - disaster risk reduction.
Sep 2, 2022 The collaborative project "Standardisiertes Monitoring von Wachstumsreaktionen wichtiger Waldbaumarten auf klimatische Extremereignisse" (MW³) with participation of the UFZ will develop a standardized monitoring system and protocol to record growth responses of important Central European forest tree species with a focus on climatic extremes. Future extreme events and their impact on forest carbon fluxes in Germany will be analyzed using smart models.

Aug 20, 2021 Open house days of the Swabian MOSES Campaign received large public interest. A research consortium of several Helmholtz centers, universities and the German Weather Service, investigates the cause and effects of hydro-meteorological extremes such as heavy thunderstorms, high precipitation and floods as well as heatwaves and droughts. The MOSES initiative is coordinated by the UFZ.
Aug 17, 2021 Start of the third phase of Collaborative Research Centre AquaDiva , investigating the links between surface and subsurface signals in the earth critical zone. Two projects are lead by researchers of CHS. They will investigate with modeling and observations how temporal and spatial variation of surface input and processes during subsurface transit drive the water flow and element transport to groundwater and rivers.

) with a state-of-the-art compilation of observed soil moisture data from 40 locations and four different measurement methods in Germany. We show that the expressed stakeholder needs for higher resolution drought information at the one-kilometer scale can be met and that the agreement of simulated and observed soil moisture dynamics can be moderately improved.
