Janine,
The data model envisioned by CF requires that the time coordinate
variable be fully enumerated. In other words, your scenario
requires "a time dimension at the highest rate", including a time
coordinate value for every time step. time(:) = 0.00, 0.04, 0.08
seconds, etc. I am not aw
Martin,
this is a bit more complicated
the radiative fluxes used in climate studies are usually spectrally
integrated and usually for these bradband fluxes there is a distinction
between solar broadband and IR broadband fluxes.
now for these broadband fluxes we also like to distinguish between
Hi again,
more on the CASTNET data. They provide
15,WINDSPEED,m/sec,"Vector wind speed; m/sec.",NUMBER,"16,4",
and
23,WINDSPEED_SCALAR,m/sec,"Scalar wind speed; m/sec.",NUMBER,"16,4",
The first appears to be a vector average = sqrt( mean(u)**2 + mean(v)**2 )
the second is = mean( sqrt(u*
Nan,
unfortunately I don't know the instrument type. I am dealing with the
CASTNET data http://java.epa.gov/castnet/ and I am primarily interested in
ozone. A brief search didn't turn up any info on the instrument type. But

Hi Roy,
thanks - yes: I think that would do. I am not an expert in this field and
don't know if the light meter spectral response is close enough to what models
generally consider "shortwave flux", but this might be a rather fine point.
In any case it would be good if a search for "irradi
Hello -
It would be useful to know what type of measurement you're
working with. Is it an observed variable? What kind instrument
made the measurement, and at what position - i.e is it on a surface
buoy?
We use surface_downwelling_shortwave_flux_in_air for swr
measured by an Eppley PSP (Precisio
Hi Martin,
There are two Standard Names 'downwelling_shortwave_flux_in_air' and
'downwelling_longwave_flux_in_air'. Do either of these fit your data. I have
associated the former with downwelling irradiance data from PAR
cosine-collector light meters.
Cheers, Roy.

Dear colleagues,
I am trying to clean up some data files and make them CF compliant. But I
am confused about the standard name that I could use for (measured)
irradiation. There is an entry
"downwelling_spectral_radiative_flux_in_air
Downwelling radiation is radiation from above. It does no
