EPIC netCDF Conventions for Time Series
Data
This document describes the PMEL-EPIC/Time_Series convention
for writing netCDF data files with the EPS library, for use
with the EPIC software package for oceanographic data.
Documentations located at ftp://ftp.unidata.ucar.edu/pub/netcdf/Conventions/PMEL-EPIC
describe the Conventions common to all PMEL-EPIC style netCDF
data files. Please see the accompanying documents describing
Conventions specific to specific data types:
This document is an addendum to the PMEL-EPIC Conventions document
in the Unidata /pub/netCDF/Conventions/PMEL-EPIC
directory, describing those characteristics which are specific
to time series data.
The global attributes here are recommended for use with time
series data. Additional attributes may be defined by the user.

Notes: * Required for data files containing CTD-type data (profile
data). All other attributes are optional. Additional attributes
can be included as desired.
"i" is integer

"r" is real
"length" is maximum length in bytes for all types
AUTO means the attribute is set automatically by the EPS library.
