Presentation transcript:

How to handle multiple vertical references For a profile with different vertical axes, we propose that: The DAC use the N_PROF dimension in the NetCDF variables to record the different vertical axes. To describe each vertical axes : 1. In the profile file add : Char VERTICAL_SAMPLING_SCHEME(N_PROF, STRING256) Vertical_sampling_scheme contains standardized name : "Argo CTD sampling" "Non pump sea surface temperature" "Non pump near surface CTD" "Low resolution oxygen sampling" 2 : In the metadata file : Add the dimension N_PROF to : char SENSOR(N_PROF,N_PARAM,STRING16); SENSOR:long_name = "List of sensors on the float "; SENSOR:conventions = "Argo reference table 3"; SENSOR:_FillValue = " "; And also to : SENSOR_MAKER, SENSOR_MODEL…, SENSOR_RESOLUTION

How to handle multiple vertical references For multiprofile files available from GDAC : They will only contain the "Argo CTD sampling" dimension. The variable "Vertical_sampling_scheme" will not appear in the GDAC multi-profile files.
