Summary of MetOcean DWG and INSPIRE TWG AC-MF Use Cases

These are the harmonised use cases for the MetOcean DWG and INSPIRE TWG AC-MF (Thematic Working Group on Atmospheric Conditions and Meteorological Features). Each use case is owned by an individual. Where there is a correspondence between the MetOcean and INSPIRE use cases, then a single use case will be developed and used by both modeling groups.

MO.DWG Use Case	INSPIRE Use Case	Editor / Owner	Category	Notes on Harmonisation
1: Future Aviation	-	AaronBraeckel	Aviation
2: Current Aviation	-	PeterTrevelyan	Aviation
3: Routine Operational Forecasting in Support of Severe Weather Warning Service	-	Possibly FredericGuillaud	Routine Forecast Production / Emergency Response	Original use case focussed on routine severe weather forecasting kept.
4: Multi-Model Ensemble Forecasting to Reduce or Mitigate Impacts of Landfalling Hurricane	-	JohnSchattel	Emergency Response
5: Routine Decision Support for Winter Highways Maintenance	-	BruceWright (should be someone else?)	Routine Decision Support
6: Seasonal, Decadal & Climate Prediction Impact Assessment	IUC4: Use of Climate Change Scenarios	BruceWright	Routine Decision Support	UC6 extended into decadal & climate prediction, with removal of climate record and specific example of agriculture in India
7: Climate Assessment based on Past Data	IUC3: Climate Assessment (past data)	JeremyTandy	Routine Decision Support	UC7 re-focussed climatology, with removal of climate prediction and specific example of economic development in sub-saharan Africa
8: Integration of Weather Data with Efforts to Combat Wildfires	-	JohnSchattel	Emergency Response	Renamed to make this specific to Wild Fires, as Emergency Response covered in other uses cases
9: Sustained Environmental Science Campaign	-	AndrewWoolf	Environmental Science Campaign
10: Automated Steering of High-resolution Local Weather Forecast Models	-	BenDomenico	Routine Forecast Production
11. Flood Forecasting	IUC2: Flood Forecasting	Possibly FredericGuillaud	Emergency Response	UC11 extended to cover range of flooding forecasting scenarios, not just use ensembles. Interface with Hydrology (i.e. OGC Hydrology DWG and INSPIRE Annex 1 Hydrography TWG) needs to be carefully managed
12:Plume Forecasting in Support of Emergency Response	IUC1: Use of Meteorology in Support of Emergency Response (Plume Forecasting)	BruceWright	Emergency Response	As the INSPIRE use case is now specific to Plume forecasting, it has been included as a new case on the harmonised list

Use Case Categories

Below is a proposal to categorise the use cases, with a further sub-categorisation, with some details, where known. The proposed harmonised MO.DWG use case are included to show how these cover the categories. However, the list of categories and sub-categories is incomplete.

Category	Sub-category	Further Detail	!MetOcean Use Case
Aviation	Future Aviation	Airport Weather, Optimal Flight Path	1: Future Aviation
	Current Aviation		2: Current Aviation
Routine Forecast Production	Severe Weather Elements	Wind, Rain, Snow, Ice, Extreme High or Low Temperatures, Thunderstorms, Tornadoes	3: Routine Operational Forecasting in Support of Severe Weather Warning Service
	?	?	10: Automated Steering of High-resolution Local Weather Forecast Models
Emergency Response	Severe Weather Elements	Wind, Rain, Snow, Ice, Extreme High or Low Temperatures, Thunderstorms, Tornadoes	3: Routine Operational Forecasting in Support of Severe Weather Warning Service
	Hurricane	Track, Intensity, Landfall. Probabalistic, often using ensembles	4: Multi-Model Ensemble Forecasting to Reduce or Mitigate Impacts of Landfalling Hurricane
	River Flooding	Fluvial, but including Flash-Flood (in 'River Canyons') and Longer Term Flooding	11. Flood Forecasting
	Coastal Flooding	Height of Surge, Height of 'Total Water', Probability of Exceedence of Thresholds. "Storm-Surge" is the interaction of tides with action of wind and pressure; negative surges also important as a shipping hazard; Probabalistic estimates are obtained from ensembles	-
	Avalanche	Risk of Occurence	-
	Wildfire	Trigger Risk, Spread	8: Integration of Weather Data with Efforts to Combat Wildfires
	Plume	Fire, Chemical Release, Nuclear Release, Volcanic Eruption, Saharan dust (e.g. methodology for the identification of natural african dust episodes in PM10 and PM2.5, as the exceedances of the PM10 daily limit value need reporting under EU air quality legislation)	12: Plume Forecasting in Support of Emergency Response
Routine Decision Support	Forecast-based Decision Support	Most meteorological parameters	5: Routine Decision Support for Winter Highways Maintenance
	Climatology Based Decision Support	Most meteorological parameters	6: Seasonal, Decadal & Climate Prediction Impact Assessment
	Climate Prediction Based Decision Support	Primarily temperature, Precipitation	7: Climate Assessment based on Past Data
Environmental Science Campaign	Short Environmental Science Campaign	Small number ot organisations, lasting only a few days	-
	Sustained Environmental Science Campaign	Large international activity, involving a large number of organsations, lasting months	9: Sustained Environmental Science Campaign
