pytesmo 0.1.3

python Toolbox for the Evaluation of Soil Moisture Observations

Package Documentation

Latest Version: 0.6.8

Introduction to pytesmo a python Toolbox for the Evaluation of Soil Moisture Observations

pytesmo is a package which aims it is to provide a standard library that can be used for the comparison and validation
of geospatial time series datasets with a focus on soil moisture.

It contains an expanding collection of readers for different soil moisture datasets (see `Supported Datasets`_) as well as routines for comparing them.
Special classes in the module :mod:`pytesmo.grid` provide easy nearest neighbor searching between datasets as well as
the calculation of lookup tables of nearest neighbours. They also provide possibilities to easily read all
grid points of a dataset in the correct order.

It contains the code used for the calculation of metrics by the
`Satellite Soil Moisture Validation Tool For ASCAT <http:"" validation_tool="" ascat.html="">`_. See :mod:`pytesmo.metrics`.


* easily read data from the `Supported Datasets`_
* anomaly calculation based on climatology or using a moving window see :mod:`pytesmo.anomaly`
* easy temporal matching of time series see :mod:`pytesmo.temporal_matching`
* multiple methods for scaling between different observation domains (CDF matching, linear regreesion, min-max matching) see :mod:`pytesmo.scaling`
* calculate standard metrics like correlation coefficients, RMSD, bias,
as well as more complex ones like triple collocation or MSE as a decomposition of the RMSD see :mod:`pytesmo.metrics`
