Hi Ghansham,
I think what it wants you to do is the following (but am not 100% sure): Say you have a profile variable like this: float abs(x,y,z) ; abs:standard_name = “atmosphere_absorption_optical_thickness_due_to” If you want to add multiple wavelengths to it, add a new dim: float abs(x,y,z,wl); abs:standard_name = “atmosphere_absorption_optical_thickness_due_to" Then add another variable: float wl(wl): wl:standard_name = “radiation_wavelength” If you really want to be explicit, add a coordiantes attribute to the abs: float abs(x,y,z,wl); abs:standard_name = “atmosphere_absorption_optical_thickness_due_to" abs:coordinates = “x y z wl” Since I also have some ocean profile data with CDOM at the seawifs wavelengths, the above was how I was planning on storing them in netcdf files (with some differences due to non standard z levels). I hope this helps (and I hope I’m not wrong). -Barna From: Discussion around CF Conventions <[email protected]> On Behalf Of Ghansham Sangar Sent: Sunday, September 15, 2019 10:34 PM To: [email protected] Subject: [CF-CONVENTIONS] coordinate variable standard_name "radiation_wavelength" Hi. Following url mentions for some of the variable names starting with "atmosphere_absorption_optical_thickness_due_to" string to have a coordinate variable with standard name "radiation_wavelength" or "radiation_frequency" http://cfconventions.org/Data/cf-standard-names/66/src/cf-standard-name-table.xml Can you just elaborate how to do this. I could not find anywhere in the CF1-.7 conventions document or even 1.8, that there can be coordinate variables with such a standard name. I have hyperspectral data that I want to write with wavelength as one dimensions. regards Ghansham
