Application Areas
A WMO Application Area is an activity involving the direct use of observations that allows National Meteorological and Hydrological Services or other organizations
to render services related to weather, climate and water, and other environmental events, contributing to public safety, socioeconomic well-being and development
in their respective countries. The concept of a WMO Application Area is used in the framework of the WMO RRR and describes a homogeneous activity for which it is
possible to compile a consistent set of observational user requirements agreed upon by community experts working in this area.
The table below lists all application areas and the respective focal points maintaining requirements for these. For any enquiries or questions on
particular requirements recorded in OSCAR, please contact the focal points directly, where an email address is provided.

| 2.2 High-Resolution Numerical Weather Prediction | High-resolution (HR) Numerical Weather Prediction (NWP) focuses on observing systems required by high-resolution NWP models producing forecasts of meteorological events with a 1-5 km horizontal resolution, 6 hours to a few days ahead. Such forecasts are more detailed than those available from global models, due to more realistic descriptions of atmospheric phenomena such as clouds and precipitation. The added detail is made possible by a finer computational grid on a specific area, more detailed specification of terrain, more sophisticated prescription of physical processes mainly based on explicit rather than parameterised formulations, and, importantly, denser and more frequent observations (with respect to global NWP) to specify appropriately detailed initial conditions. | Magnus Lindskog magnus.lindskog@smhi.se |

| 2.3 Nowcasting / Very Short-Range Forecasting | Nowcasting, as outlined by the World Meteorological Organization (WMO), involves detailed forecasting of local weather, utilizing any method to predict conditions from the present to six hours ahead. It provides a comprehensive portrayal of the current weather, leveraging real-time observational data such as surface observations, satellite imagery, lightning, radar data, etc. Nowcasting by extrapolation excels in delivering high-resolution forecasts of weather phenomena for the immediate (2 hour) future. Advancements in data assimilation systems enable Numerical Weather Prediction (NWP) to outperform nowcast extrapolation thereafter. The use of NWP with data assimilation forms the basis of Very Short Range Forecasting (VSRF) up to 12 hours. To ensure a seamless VSRF, crucial in high-impact weather situations, advanced centers blend both NWP and nowcasting. This integration plays a vital role in issuing timely warnings and aiding decision-makers across various sectors. | Aitor Atencia Ruiz de Gopegui aitor.atencia@geosphere.at |

| 2.6 Atmospheric Composition Forecasting and Monitoring | Applications related to evaluating and analysing temporal and spatial changes in atmospheric composition, at regional and global scale. They aim to support treaty monitoring, climatologies, and re-analyses, assessing trends in composition and emissions/fluxes, and to better understand processes, principally in the troposphere and stratosphere. The applications rely on the use of data of controlled quality with less stringent time requirements compared to the near-real-time requirements. These data are also used to derive products that are published in the WMO ozone and greenhouse gas bulletins and the state of the atmosphere reports (for example, Scientific Assessment of Ozone Depletion reports). | Richard Eckman richard.s.eckman@nasa.gov |

Data related to tsunamis are acquired with both high frequency and high precision. The essential elements for early detection include the real-time transmission of seismic data, sea-level observations, and GNSS (Global Navigation Satellite System) measurements, which together provide a critical foundation for the effective monitoring and early warning against tsunami threats. | Yuji Nishimae nishimae@met.kishou.go.jp |

| 3.5 Marine Environmental Emergency Response | Marine environmental emergency response (MEER) refers to the response of any immediate and imminent threat of harm to the marine environment. This response is highly time sensitive as marine pollutants drift and disperse in the surrounding fluid and, thus, increasing the extent of the potential environmental harm. The time sensitivity of the data required to monitor and predict the transport of pollutants is of the utmost importance to mitigate damage to the marine environment. | Graigory Sutherland graigory.sutherland@ec.gc.ca |
