The High-resolution Earth System monitoring and diagnostics for sustainable applications (HIRES-APP) proposal deals with deriving and applying novel vertical profiling methods in the atmospheric boundary layer (ABL) and evaluating their impact on high-resolution regional (re)analysis and consequently also on short-term weather forecasts.
In order to improve high quality regional Earth System monitoring, HIRES-APP will collaborate with our new partner University of Tübingen, where we will assess the quality of novel Uncrewed Aerial Systems (UAS) observations for continuous monitoring, thus creating a stronger HErZ virtual institution and progressing in the area of DWD’s future data acquisition concept. The proposed research also includes the development of new observational methods based on the upcoming MTG Sounder satellite mission and ground-based observation networks and will assimilate the retrieved profiles into ICON-D2 applying DWD’s KENDA (Km-Scale Ensemble Data Assimilation). Advanced process-oriented probabilistic evaluation approaches, which can diagnose physical balances on the different scales at stake will be developed and applied to the outcomes of the retrievals and data assimilation experiments.
Continuing on from FESSTVaL, we plan to carry out the regional VITAL I & II campaigns, which will focus on profiling the lower troposphere in the Aachen-Cologne-Bonn (O~100km) region. The campaigns will not only deliver the required unique vertical profiling data, but in addition be linked in time to the WMO UAS demonstration campaign, the launch of MTG-S and the proposed HErZ summer school for vertical profiling. Next to the opening of two lectures on Energy Meteorology and Earth System Observation at the universities of Cologne and Bonn for young HErZ scientists, the summer school will be a part of securing and strengthening the networked meteorology and climatology education within HErZ.
HIRES-APP will also contribute to optimally exploiting weather and climate information for society. With our partner EWI, a stakeholder-oriented energy index that quantifies the impact of weather events on the energy system will be developed. The index will serve to communicate forecasts of different time scales to relevant energy system stakeholders. Also, wind gust parametrizations and fire warning alert data using state-of-the-art ground-based FESSTVaL observations, reanalysis data and warnings, will be conceptualized.
