act.io.Icartt#

class act.io.Icartt[source]#

Container for an ICARTT FFI 1001 file: the full header model plus the data records. Reads and writes the format described by ESDS-RFC-029v2.

Attributes are named after the fields in the standard, so the header can be inspected and edited directly before writing.

Examples

from act.io.icartt import Icartt

ict = Icartt.from_file('AAFNAV_COR_20181104_R0.ict')
print(ict.NV, ict.keywords['PLATFORM'])
ds = ict.to_xarray()

`from_file`(filename[, delimiter])	Read an ICARTT FFI 1001 file.
`from_xarray`(ds[, filename])	Build an Icartt from an xarray.Dataset produced by `read_icartt()`.
`to_xarray`()	Convert to an xarray.Dataset with a `time` coordinate.
`write`([filename, fmt, delimiter])	Write the object to an ICARTT FFI 1001 file.

`NCOM`	Normal comment lines, rebuilt from the parsed parts.
`NLHEAD`	Number of header lines.
`NNCOML`	Number of normal comment lines.
`NSCOML`	Number of special comment lines.
`NV`	Number of dependent variables (header line 10).
`VMISS`	Missing data flags, one per dependent variable (header line 12).
`VSCAL`	Scale factors, one per dependent variable (header line 11).
`times`	Time steps of the data as a `numpy.datetime64[ns]` array.
`variables`	All variables, independent first, keyed by short name.
