New P01 request - "Remote-sensing reflectance of the water body" (BODCNVS-1392) #125
Comments
I initially thought that having 'remote sensing' in an entity name was a bad idea until I read the CF definition and the NASA description of the parameter at https://oceancolor.gsfc.nasa.gov/atbd/rrs/ . I reckon both the standard name and O'Reilly et al relate to the NASA algorithm, although the algorithm could have changed over time. |
Thanks Roy. Apologies I should have specified the "unspecified wavelength" or "wavelength specified elsewhere in metadata". We'd prefer to go that route than having a parameter every 2 nm covering the range 320-900nm. |
Would have loved to have gone down that route in the past - P01 would be a lot slimmer - but was constrained by QXF and the sample schema data model!! |
So could the modelisation of the new term according to the P01 semantic model be: |
Hi, Is there a time-line for this code to be added? It is needed for a dataset we've been asked to publish with a DOI. Cheers |
Hi Rob, no there isn't but I'll try and get it done for you by Monday. Cheers, Gwen. |
Hi Gwen, Did you get a chance to publish this yesterday? Cheers |
Hi @robthomas-marine, Gwen didn't manage to get to this but I am picking this up now. Thanks! |
Hi @robthomas-marine, this has now been loaded to P01, I will confirm that it's live tomorrow morning. Code: RRSPSTR1 |
Hi Dani, Many thanks for sorting this code. Cheers |
Live on the NVS as https://vocab.nerc.ac.uk/collection/P01/current/RRSPSTR1/ |
Please could a new S06 (i.e. property) term for “Remote-sensing reflectance” be created and then used in combination with the S26 matrix “water body” to create a P01 term "Remote-sensing reflectance of the water body"?
Definition below:
Remote sensing reflectance (Rrs, units: sr−1) is defined as the ratio of water-leaving radiance (Lw, units: µW cm−2 sr−1 nm−1) to downwelling irradiance just above the sea surface (Es, units: µW cm−2 nm−1) (O’Reilly et al., 1998).
This would be an equivalent P01 term for the CF standard name (P07)
CFV13N26
surface_ratio_of_upwelling_radiance_emerging_from_sea_water_to_downwelling_radiative_flux_in_air
Units are "per steradian" (P06: PSTR)
Thanks
