pymetkit
pymetkit is a Python interface to metkit, ECMWF's
meteorological toolkit. It exposes the MARS request model in a Pythonic way, built on a
pybind11 extension module (pymetkit_bindings) that binds the
metkit C++ library directly.
The native libmetkit shared library and its dependencies are located at runtime via
findlibs.
Architecture
pymetkit_bindings— compiled pybind11 module bindingmetkit::mars::MarsRequestandmetkit::mars::MarsExpansion.pymetkit._internal— loads the native library viafindlibs, initialises the bindings, and re-exports the raw symbols.pymetkit— the Pythonic layer:MarsRequest(a verb plus aMarsSelection),MarsSelection(a type alias for the user-facing key-value mapping),UserInputMapper(normalisesMarsSelectionvalues to and from the internaldict[str, list[str]]representation), andparse_mars_request.
Usage
from pymetkit import MarsRequest, parse_mars_request
# Build a request from a verb and a selection
request = MarsRequest(
"retrieve",
{
"class": "od",
"domain": "g",
"date": "-1",
"expver": "0001",
"step": range(0, 13, 6),
},
)
# Expand against the MARS language definition
expanded = request.expand()
print(expanded.verb(), dict(expanded))
# Parse requests from a string or a file
requests = parse_mars_request("retrieve,class=od,date=-1,param=129,step=12")
Command line
python -m pymetkit --print-home # metkit library home
python -m pymetkit --print-home-deps # all dependency homes and versions
