| Sumario: | <p>Understanding soil moisture dynamics at the sub-kilometre scale is
increasingly important, especially with the continuous development of
hyper-resolution land surface and hydrological models. Cosmic-ray neutron
sensors (CRNSs) are able to provide estimates of soil moisture at this
elusive scale, and networks of these sensors have been expanding across the
world over the previous decade. However, each network currently implements
its own protocol when processing raw data into soil moisture estimates. As a
consequence, this lack of a harmonised global data set can ultimately lead to
limitations in the global assessment of the CRNS technology from multiple
networks. Here, we present crspy, an open-source Python tool that is designed
to facilitate the processing of raw CRNS data into soil moisture estimates
in an easy and harmonised way. We outline the basic structure of this tool,
discussing the correction methods used as well as the metadata
that crspy can create about each site. Metadata can add value to global-scale studies of field-scale soil moisture estimates by providing additional
routes to understanding catchment similarities and differences. We
demonstrate that current differences in processing methodologies can lead to
misinterpretations when comparing sites from different networks and that having a
tool to provide a harmonised data set can help to mitigate these issues. By
being open source, crspy can also serve as a development and testing tool
for new understanding of the CRNS technology as well as being used as a
teaching tool for the community.</p> |
