ncdatasets

There functions were adapted from an old version of NCDatasets.jl

data and def modes

NetcdfIO.NCDataset — Type

mutable struct NCDataset{TDS} <: CommonDataModel.AbstractDataset

Struct for a NetCDF dataset

Fields

parentdataset::Any: Parent dataset (nothing for the root dataset)
ncid::Int32: NetCDF dataset id
iswritable::Bool: Whether the NetCDF is writable
isdefmode::Ref{Bool}: Whether the NetCDF is in define mode (i.e. metadata can be added, but not data)

source

NetcdfIO.Variable — Type

struct Variable{T, N, TDS<:CommonDataModel.AbstractDataset} <: CommonDataModel.AbstractVariable{T, N}

Struct to represent a NetCDF variable

Fields

ds::CommonDataModel.AbstractDataset: Parent NetCDF dataset
varid::Int32: NetCDF variable id
dimids::NTuple{N, Int32} where N: NetCDF dimension ids

source

NetcdfIO.data_mode! — Function

Set data mode for NCDataset

source

NetcdfIO.def_mode! — Function

Set define mode for NCDataset

source

CommonDataModel.defVar — Function

defVar(ds::NCDataset,
       var_name::UnionNameTypes,
       var_type::DataType,
       var_attrib::UnionAttrTypes,
       dim_names::Vector{String};
       deflatelevel::Union{Int,Nothing} = nothing)

Create a new variable in the dataset, given

ds A netcdf dataset
name Name of the variable
vtype Type of the variable, for example Float64, Int32, String, etc.
attrib Variable attributes
dimnames Dimension names in the netcdf file
deflatelevel Compression level fro NetCDF, default is nothing
