Upendra, >From the perspective of the UDUNITS unit-packages, the unit "Forel-Ule" is the unit "Forel" multiplied by the unit "Ule" -- neither, of which, is known by the UDUNITS or UDUNITS2 packages. I suggest you contact the author. Regards, Steve Emmerson On 12/08/2011 09:05 AM, Upendra Dadi wr

Hi Upendra, We had some similar data from the Secchi disc depth observations and related data recording the observed sea water colour on the Forel-Ule water colour scale. The Forel-Ule scale is a set of character codes F1,F3 ...F11, U1, U3U11 corresponding to known colour standards e.g F1

Dear Upendra We had a long discussion about this in 2009. In particular, John Graybeal's posting of 25 Mar 2009 gives several different pH definitions. It appeared that these versions of pH are probably not the same geophysical quantity, and it is therefore necessary to specify which one it is. Al

Hi, I have some data which has "Forel-Ule" for the units used. Is there a udunits corresponding to this? Also, what should I be using for milliequivalent ? Thanks for the help. Upendra ___ CF-metadata mailing list CF-metadata@cgd.ucar.edu http:/

Hi Upendra, The reason the "reporting scale" is attached to this name is that the fundamental measurement, or property, to which it refers produces numbers that are not comparable to pH derived using other techniques. (They are actually measuring different quantities, not just a different offse

Hi All, The standard name table has an entry called "sea_water_ph_reported_on_total_scale". I have some data which does not mention the scale used for the measurement of ph. Should there be an another entry which does not mention the scale? Most of the standard names I have seen doesn't men
