Is anyone aware of a suitable standard name for the NCEP GRIB-1
variables "Surface lifted index " (131) and "Best (4 layer) lifted
index" (132) as I can't find anything in the current list (v18).
Kind regards,

y a standard_name of
"land_area_fraction", but the variable is named "Land_cover_land1sea0"
and only has values "1.0" and "0.0" and standard name"land_binary_mask"
would seem more appropriate - which has a GRIB variable value listed as
E172.

OK, I've worked out that the E values represent ECMWF defined values,
and N values represent NCEP definded values (GRIB values 128-254
reserved for originating centre).

In the standard name table what do the E numbers in the GRIB column
denote, i.e. E151 (air_pressure_at_sea_level), E130 (air_temperature). I
understand what the plain numerical values represent, i.e. 1 equals
pressure, 2 equals pressure reduced to MSL etc. Having decoded some GRIB

Hi,
Have just upgraded ERDDAP to v1.36 and attempted to add a new GRIB file
and note that when I run GenerateDatasetsXml.bat the dataset XML
generated includes the line GRID,
listed as a source attribute. Take it this is meant to relate to CF
Discrete Sampling Geometries convention, but seems odd

via THREDDS and ERDDAP the use of other file suffix, such as ".grb" for
GRIB files, has not caused any issues or stopped us from state
conformance with conventions such as CF.

Bonjour Alain,
Being new to the world of meteorological/oceangraphic data myself
recently, I had the same problem you have when reading the various
conventions available. Based upon discussions about this matter, and how
others are using and interpretating the conventions, I personally have

Hi,
The COARDS covention mandates the use of the "positive" attribute for a
vertical axis that is not a unit of pressure, i.e. if using metres to
denote altitude. It further qualifies use of the "positive" attribute as
a means of discovering vertical coordinate variables, i.e. the

Hi,
The use of the variable unit value "degrees" would appear to discount a
data set from being both COARDS and CF compliant, at least according to
the CF conventions document, i.e. v1.5, section 3.1 states "The COARDS
