Hello,I have a netcdf file (chlorophyll gridded satellite daily map) in which I have my variable chl(tim,lat,lon), then the vector of regular lat and a vector for
regular lon.
My grid mapping is Equidistant Cylindrical. SO in the nc I set as
GLOBAL ATTRIBUTE
----------------------------------
attname=Conventions
value=CF-1.4
attname=grid_mapping
value=Cylindrical
------------------------------------
A collegue of mine told me that for CF 1.4 the grid_mapping is no more
a global attribute but it is a variable attribute named as
"grid_mapping_name".
BUT I run the CF checker for 1.4 on my file and everything is ok!!!!
first question:
Is it still correct /with cf 1.4) to set a global attribute as "grid_mapping"?
or must I put the same information as variable attribute? in this case, how?
second question:
are "Equidistant Cylindrical" and "Cylindrical" still valid values for
grid_mapping (or grid_mapping name)?
thanks in advanced
Cristina
