  1. What lies underneath science parameters Luis Bermudez MMI 2007

  2. Parameters Composition Parameters are composed (implicitly or explicitly) of the following: • Complex properties • Complex observables • Complex methods Examples from CF and BODC are enclosed

  3. CF - Air_temperature Property Temperature of air Observable

  4. BODC code GTKCMA01 Second maximum level of waves on the water column by waverider and manual record analysis

  5. Complex Property Second maximum level of waves on the water column by waverider and manual record analysis Complex Observable Complex Method

  6. BODC code ANH3FIPT ComplexObservable Complex Property Concentration of ammonium {NH4} per unit volume of the atmosphere [particulate phase] by filtration with teflon filter and flow infection gas diffusion analysis ComplexMethod

  7. BODC code ANH3FIPT ComplexProperty Concentration of ammonium {NH4} per unit volume of the atmosphere [particulate phase] by filtration with teflon filter and flow infection gas diffusion analysis ComplexObservable ComplexMethod

  8. CF - Change_over_time_in _surface_snow_amount ComplexProperty Change_over_time_of_ snow_amount_ in_surface Complex Observable No method ComplexMethod

  9. CF - Change_over_time_in _surface_snow_amount ComplexProperty Change_over_time_of_ snow_amount_ in_surface Complex Observable No method ComplexMethod

  10. BODC - HEADCM01 ComplexProperty Orientation (horizontal relative to true north) of measurement platform {heading} by compass Complex Observable ComplexMethod

  11. CF - mass_concentration_ of_sulfate_aerosol_in_air ComplexProperty mass_concentration_ of_sulfate_aerosol in Air Complex Observable

  12. BODC 488LRXUU ComplexProperty Upwelling radiance as energy (488nm wavelength) in the water column by radiance sensor Complex Observable ComplexMethod

  13. EDCS - ACCUM_PRECIP_24_HOUR ComplexProperty ACCUM_PRECIP_24_HOUR Atmosphere Complex Observable (Implicit)

  14. Questions • What constitutes a Complex Property ? • What constitutes a Complex Observable ? • What constitutes a Complex Method ? • How far can we go with CF?

  15. BNF for CF ? < > variable (or non terminal) [ ] optional | or { } 0 or more string - is a terminal property ::= <simpleProperty> | <complexProperty> simpleProperty ::= <observable> <dimension> complexProperty ::= <dimension><dimensionModifier><observablePhrase> observablePhrase ::= ( in <medium> | <earthRealm> ) | ( at <PhisicalObject> ) observable ::= <medium> | <earthRealm> | <PhisicalObject> medium ::= air | water earthRealm ::= seaSurface | seaBottom | seaFloor | atmosphere PhisicalObject ::= platform
