Bulk request for weather related "terms"

[easr]

Hi Pier,

as discussed in our call, please find below the list of "terms" that will be great to have them in ENVO. As agreed, there will be a clear separation of the phenomena from the calculation/predictions, thus many of the "terms" below will end up reduced to one single term.

AverageCloudCover AverageDewpoint AverageRH AverageSurfaceTemperature AverageTemperature AvgLongwave(UpFlux) AvgNet(In-Out) AvgPollution/Haze AvgPressure AvgShortwave(DownFlux) AvgWindSpeed DateTime Daylight Elevation Evapotranspiration GeoHash Grid IceAccumulation Latitude LeafWetness LeafWetnessIndex LiquidAccumulation Longitude MaxCloudCover MaxDewpoint MaxLongwave(UpFlux) MaxNet(In-Out) MaxPollution/Haze MaxPressure MaxRH MaxShortwave(DownFlux) MaxSurfaceTemperature MaxTemperature MaxWindSpeed MinCloudCover MinDewpoint MinLongwave(UpFlux) MinPollution/Haze MinPressure MinRH MinShortwave(DownFlux) MinSurfaceTemperature MinTemperature MinWindSpeed Moisture% PoreWaterPressure PrecipAccumulation PrecipAccumulationforPeriod PrecipAccumulationnormalized PrecipDuration PrecipitationRate SnowAccumulation SnowDensity SnowDepth SurfaceAvgWindSpeed SurfaceGust SurfaceMaxWindSpeed SurfaceMinWindSpeed Temperature WindDirection

thanks a lot in advance! Erick

Hi Pier Luigi, we would like to jump on this conversation to asked for the weather related terms needed in AgrO:

CO2 concentration in the atmosphere Day length from twilight to twilight Photosynthetically active radiation (PAR) Photosynthetic photon flux density (PPFD) Solar radiation Runoff quantity daily Relative humidity, minimum daily Relative humidity, maximum daily Relative humidity at maximum temperature

Let us know if you need more precision. Thanks!

Hi @easr

🚧 Work in progress 🚧 Should wrap up tomorrow.

As discussed, ENVO will represent the real world phenomena that these labels are about, but won't include representations of mathematical operations or other abstractions. Those should be handled in another ontology or light-weight vocab/thesaurus. Ontologies like IAO or STATO may be of interest there.

At any rate, the aboutness links to ENVO classes can go quite a way to semantically enhance these concepts and link them to other resources (which may have separate mathematical conventions).

In scope

Term	ENVO Class	Comments
AverageCloudCover	cloud cover
AverageDewpoint	dew point
AverageRH	humidity	Consider using this PATO term - relative humidity is more a derived quantity than a metaphysical one.
AverageTemperature	temperature	of what? temperature is a PATO term, but ENVO can link it to an environmental entity (e.g. the atmosphere)
AvgLongwave(UpFlux)	outgoing longwave radiation	Confirm this is what is meant here
AvgPollution/Haze	haze	A class for "air pollution" could be created, if haze isn't sufficient
AvgPressure	pressure of air	assuming air pressure
AvgShortwave(DownFlux)	shortwave radiation	Can't guess the way "flux" is meant here.
AverageSurfaceTemperature	temperature	Surface of what? If we have better definition, then we can specialise this
AvgWindSpeed	atmospheric wind speed	The averaging is external
Elevation	elevation	a PATO term, ENVO can specialise this by linking it to an environmental entity. Better to post-compose though.
Evapotranspiration	evapotranspiration
IceAccumulation	ice accumulation process	this is a process, we can also reference the actual ice mass if that's what's needed.
LiquidAccumulation	liquid accumulation process	as with the ice accumulation term, this is assumed to be the process rather than the accumulation of liquid itself.
MaxCloudCover	cloud cover
MaxDewpoint	dew point
MaxLongwave(UpFlux)	outgoing longwave radiation	Confirm this is what is meant here
MaxPollution/Haze	haze
MaxPressure	pressure of air	assuming air pressure
MaxRH	humidity	Consider using this PATO term - relative humidity is more a derived quantity than a metaphysical one.
MaxShortwave(DownFlux)	shortwave radiation	Can't guess the way "flux" is meant here.
MaxSurfaceTemperature	temperature	Currently just the PATO temperature term; we can specialise it if we know what the surface is
MaxTemperature	temperature	of what? see above
MaxWindSpeed	atmospheric wind speed
MinCloudCover	cloud cover
MinDewpoint	dew point
MinLongwave(UpFlux)	outgoing longwave radiation	Confirm this is what is meant here
MinPollution/Haze	haze	see above
MinPressure	pressure of air	assuming air pressure
MinRH	humidity	Consider using this PATO term - relative humidity is more a derived quantity than a metaphysical one.
MinShortwave(DownFlux)	shortwave radiation	Can't guess the way "flux" is meant here.
MinSurfaceTemperature	temperature	surface of what? See above.
MinTemperature	temperature
MinWindSpeed	atmospheric wind speed
PrecipAccumulation	hydrological precipitation process	we could specialise this more, to reference the process of accumulation
PrecipAccumulationforPeriod	hydrological precipitation process	we could specialise this more, but would need more information
PrecipAccumulationnormalized	hydrological precipitation process	This could be matched to an accumulation of precipitation class, but the rest would be left to the calculation semantics/vocab
PrecipDuration	hydrological precipitation process	we could specialise this more, to reference a durational quality of the process of accumulation
PrecipitationRate	hydrological precipitation process	We could have the rate quality asserted here, but this may be more useful if the system handles all the other calculated quantities internally.
SnowAccumulation	snow accumulation process	Assuming the process, but the mass can be created too
SnowDensity	mass density of snow
SnowDepth	depth of snow
SurfaceAvgWindSpeed	atmospheric wind speed	This can be specialised to "surface wind speed", but I'd need to know the surface of what. Also, better to post compose this.
SurfaceGust	wind gust	This can be further specialised to "surface gust", but more information on what is meant by surface is needed.
SurfaceMaxWindSpeed	atmospheric wind speed	This can be specialised to "surface wind speed", but I'd need to know the surface of what. Also, better to post compose this.
SurfaceMinWindSpeed	atmospheric wind speed	This can be specialised to "surface wind speed", but I'd need to know the surface of what. Also, better to post compose this.
Temperature	temperature	a PATO term, ENVO can specialise that to temperature of some environmental entity, but this is better post-composed
WindDirection	atmospheric wind direction

Open questions / out of scope

Term	Comments
PoreWaterPressure	Sediment? Aquifers? Needs more information. Water pressure is available, however.
AvgNet(In-Out)	Unclear
DateTime	OWL Time may work
Daylight	I can imagine ENVO creating a term like this, but I have the feeling this is far more operationally defined.
GeoHash	GIS abstraction
Grid	GIS abstraction
Latitude	GIS abstraction
Longitude	GIS abstraction
MaxNet(In-Out)	unclear
LeafWetness	Can be post-composed from PO:leaf and PATO:wetness. ENVO could pre-compose, but not sure if this is mission creep
LeafWetnessIndex	this is a derived quantity from LeafWetness
Moisture%	Unclear what this is referring to

@celineaubert @marieALaporte

Request	ENVO Term	Comments
CO2 concentration in the atmosphere	concentration of carbon dioxide in an atmosphere
Day length from twilight to twilight		What's the operational definition here? I can imagine this being a bit tricky to get right.
Photosynthetically active radiation (PAR)	photosynthetically active radiation	Represented as a process
Photosynthetic photon flux density (PPFD)		This is an odd construction - what is a photosynthetic photon? I'm working on semantics of primary production and the definitional space there is quite a mess.
Solar radiation	Solar radiation	Created as an instance of stellar radiation with Sol (linked to Wikidata) as a participant.
Runoff quantity daily		I'll need a definition to work with, finding quite a lot of variation.
Relative humidity, minimum daily	See how RH is handled in response to @easr 's request. As a calculated abstraction, the only part that would be represented in ENVO would be the humidity of X, reusing PATO humidity.
Relative humidity, maximum daily	See how RH is handled in response to @easr 's request.
Relative humidity at maximum temperature	See how RH is handled in response to @easr 's request.

@easr any other last minute needs / tweaks before we release?

@celineaubert any feedback we can fold in to this release?

@pbuttigieg : are the ones 'In Scope' already in ENVO? Perhaps in a draft version?

[easr]

@pbuttigieg : I requested to my colleagues more info about the terms in the table 'open questions /out of scope'. I hope to get more news next week.

[pbuttigieg]

Thanks @easr

The ones above are in the editors' version, here

[pbuttigieg]

@easr - just a note that many of these are now live following our last release
