https://travis-ci.org/TUW-GEO/ismn.svg?branch=master https://coveralls.io/repos/TUW-GEO/ismn/badge.png?branch=master https://badge.fury.io/py/ismn.svg https://readthedocs.org/projects/ismn/badge/?version=latest

Readers for the data from the International Soil Moisture Database (ISMN).

Citation

https://zenodo.org/badge/DOI/10.5281/zenodo.855308.svg

If you use the software in a publication then please cite it using the Zenodo DOI. Be aware that this badge links to the latest package version.

Please select your specific version at https://doi.org/10.5281/zenodo.855308 to get the DOI of that version. You should normally always use the DOI for the specific version of your record in citations. This is to ensure that other researchers can access the exact research artefact you used for reproducibility.

You can find additional information regarding DOI versioning at http://help.zenodo.org/#versioning

Installation

This package should be installable through pip:

pip install ismn

The cartopy-package needs to be installed manually by using the following command:

conda install -c conda-forge cartopy

Example installation script

The following script will install miniconda and setup the environment on a UNIX like system. Miniconda will be installed into $HOME/miniconda.

wget https://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh -O miniconda.sh
bash miniconda.sh -b -p $HOME/miniconda
export PATH="$HOME/miniconda/bin:$PATH"
git clone git@github.com:TUW-GEO/ismn.git ismn
cd ismn
conda env create -f environment.yml
source activate ismn
pip install -r test-requirements.txt

This script adds $HOME/miniconda/bin temporarily to the PATH to do this permanently add export PATH="$HOME/miniconda/bin:$PATH" to your .bashrc or .zshrc

The second to last line in the example activates the ismn environment.

After that you should be able to run:

python setup.py test

to run the test suite.

Description

ISMN data can be downloaded for free after registration from the ISMN Website

In case of the ISMN, two different formats are provided:

  • Variables stored in separate files (CEOP formatted)

    this format is supported 100% and should work with all examples

  • Variables stored in separate files (Header+values)

    this format is supported 100% and should work with all examples

If you downloaded ISMN data in one of the supported formats in the past it can be that station names are not recognized correctly because they contained the ‘_’ character which is supposed to be the separator. If you experience problems because of this please download new data from the ISMN since this issue should be fixed.

Landcover Classification

The ISMN data comes with information about landcover classification from the ESA CCI land cover project (years 2000, 2005 and 2010) as well as from in-situ measurements. To use ESA CCI land cover variables for filtering the data in the get_dataset_ids function, set the keyword parameters (landcover_2000, landcover_2005 or landcover_2010) to the corresponding integer values (e.g. 10) in the list below. To get a list of possible values for filtering by in-situ values (keyword parameter: “landcover_insitu”), call the get_landcover_types method of your ISMN_Interface object and set landcover=’landcover_insitu’.

  • 10: Cropland, rainfed
  • 11: Cropland, rainfed / Herbaceous cover
  • 12: Cropland, rainfed / Tree or shrub cover,
  • 20: Cropland, irrigated or post-flooding,
  • 30: Mosaic cropland (>50%) / natural vegetation (tree, shrub, herbaceous,
  • 40: Mosaic natural vegetation (tree, shrub, herbaceous cover) (>50%) / cropland (<50%),
  • 50: Tree cover, broadleaved, evergreen, Closed to open (>15%),
  • 60: Tree cover, broadleaved, deciduous, Closed to open (>15%),
  • 61: Tree cover, broadleaved, deciduous, Closed (>40%),
  • 62: Tree cover, broadleaved, deciduous, Open (15-40%),
  • 70: Tree cover, needleleaved, evergreen, closed to open (>15%),
  • 71: Tree cover, needleleaved, evergreen, closed (>40%),
  • 72: Tree cover, needleleaved, evergreen, open (15-40%),
  • 80: Tree cover, needleleaved, deciduous, closed to open (>15%),
  • 81: Tree cover, needleleaved, deciduous, closed (>40%),
  • 82: Tree cover, needleleaved, deciduous, open (15-40%),
  • 90: Tree cover, mixed leaf type (broadleaved and needleleaved),
  • 100: Mosaic tree and shrub (>50%) / herbaceous cover (<50%),
  • 110: Mosaic herbaceous cover (>50%) / tree and shrub (<50%),
  • 120: Shrubland,
  • 121: Shrubland / Evergreen Shrubland,
  • 122: Shrubland / Deciduous Shrubland,
  • 130: Grassland,
  • 140: Lichens and mosses,
  • 150: Sparse vegetation (tree, shrub, herbaceous cover) (<15%),
  • 152: Sparse vegetation (tree, shrub, herbaceous cover) (<15%) / Sparse shrub (<15%),
  • 153: Sparse vegetation (tree, shrub, herbaceous cover) (<15%) / Sparse herbaceous cover (<15%),
  • 160: Tree cover, flooded, fresh or brakish water,
  • 170: Tree cover, flooded, saline water,
  • 180: Shrub or herbaceous cover, flooded, fresh/saline/brakish water,
  • 190: Urban areas,
  • 200: Bare areas,
  • 201: Consolidated bare areas,
  • 202: Unconsolidated bare areas,
  • 210: Water,
  • 220: Permanent snow and ice,

Climate Classification

The ISMN data comes with information about climate classification from the Koeppen-Geiger Climate Classification (2007) as well as in-situ measurements. To use Koeppen-Geiger variable for filtering the data in the get_dataset_ids function, set the keyword parameter “climate” to the corresponding keys (e.g. ‘Af’) in the list below. To get a list of possible values for filtering by in-situ values (keyword parameter: “climate_insitu”), call the get_climate_types method of your ISMN_Interface object and set climate=’climate_insitu’.

  • Af: Tropical Rainforest
  • Am: Tropical Monsoon
  • As: Tropical Savanna Dry
  • Aw: Tropical Savanna Wet
  • BWk: Arid Desert Cold
  • BWh: Arid Desert Hot
  • BWn: Arid Desert With Frequent Fog
  • BSk: Arid Steppe Cold
  • BSh: Arid Steppe Hot
  • BSn: Arid Steppe With Frequent Fog
  • Csa: Temperate Dry Hot Summer
  • Csb: Temperate Dry Warm Summer
  • Csc: Temperate Dry Cold Summer
  • Cwa: Temperate Dry Winter, Hot Summer

  • Dwa: Cold Dry Winter, Hot Summer
  • Dwb: Cold Dry Winter, Warm Summer
  • Dwc: Cold Dry Winter, Cold Summer
  • Dwd: Cold Dry Winter, Very Cold Winter
  • Dfa: Cold Dry Without Dry Season, Hot Summer
  • Dfb: Cold Dry Without Dry Season, Warm Summer
  • Dfc: Cold Dry Without Dry Season, Cold Summer
  • Dfd: Cold Dry Without Dry Season, Very Cold Winter
  • ET: Polar Tundra
  • EF: Polar Eternal Winter
  • W: Water

Contribute

We are happy if you want to contribute. Please raise an issue explaining what is missing or if you find a bug. We will also gladly accept pull requests against our master branch for new features or bug fixes.

Development setup

For Development we also recommend a conda environment. You can create one including test dependencies and debugger by running conda env create -f environment.yml. This will create a new ismn environment which you can activate by using source activate ismn.

Guidelines

If you want to contribute please follow these steps:

  • Fork the ismn repository to your account
  • Clone the repository
  • make a new feature branch from the ismn master branch
  • Add your feature
  • Please include tests for your contributions in one of the test directories. We use py.test so a simple function called test_my_feature is enough
  • submit a pull request to our master branch

Note

This project has been set up using PyScaffold 2.5.7. For details and usage information on PyScaffold see http://pyscaffold.readthedocs.org/.
