EISCAT_3D Uncertainty Estimation (e3doubt)
e3doubt is a Python frontend to the ISgeometry R package developed by I. Virtanen (UOulu), and is a tool for estimating the uncertainties in the plasma parameters measured using the incoherent scatter radar technique with different beam configurations and radar system parameters. It is designed with EISCAT_3D in mind, but is readily adaptable to other radar configurations.
We recommend using the python scripts in the examples folder to learn how to use e3doubt. (Some of these examples require the lompe Python package.)
- python >= 3.10
- git >= 2.13
- R >= 3.4
- CMake >= 3(?) (Tested with CMake 3.22.0)
If you have a mac with brew installed, R installation should be as simple as brew install r
CMake is installable with anaconda: conda install -c anaconda cmake as of November 2023.
(NB: In the below, if you do not have mamba, replace mamba with conda)
The package may someday be pip-installable from GitHub directly with:
pip install "e3doubt @ git+https://github.com/Dartspacephysiker/e3doubt.git@main"
This could also be done within a minimal conda environment created with, e.g. mamba create -n e3doubt python=3.10 fortran-compiler
Get the code, create a suitable conda environment, then use pip to install the package in editable (development) mode:
git clone https://github.com/Dartspacephysiker/e3doubt mamba env create -f e3doubt/binder/environment.yml -n e3doubt mamba activate e3doubt pip install --editable ./e3doubt
Editable mode (-e or --editable) means that the install is directly linked to the location where you cloned the repository, so you can edit the code.
Note that in this case, the deps-from-github option means that Ilkka Virtanen's ISgeometry package will be installed directly from the source on GitHub. (THIS HAS NOT BEEN TESTED)
Once you've got everything downloaded, you'll need to run something like the following to make rpy2 aware of the ISgeometry R package. NOTE: You must have R installed on your machine for this to work
# Location of e3d install directory
e3ddir = '/path/to/e3doubt/'
# Import things we need from rpy2
from rpy2.robjects.packages import importr
from rpy2 import robjects as robj
import os
# base = importr('base')
utils = importr('utils')
# Install dependencies for ISgeometry package
utils.install_packages("maps")
utils.install_packages("mapdata")
utils.install_packages(os.path.join(e3ddir,'external/ISgeometry'),
repos=robj.NULL,
dependencies=True,
type="source")If you get errors about R not being able to locate ISgeometry, make sure that the external/ISgeometry/ directory is not empty:
You should have the following modules installed (this is handled automatically when e3doubt is install using the mamba/conda environment.yml file mentioned above):
