%description
Integration of Earth system data from various sources is a challenging
task. Except for their qualitative heterogeneity, different data records
exist for describing similar Earth system process at different
spatio-temporal scales. Data inter-comparison and validation are usually
performed at a single spatial or temporal scale, which could hamper the
identification of potential discrepancies in other scales. 'csa' package
offers a simple, yet efficient, graphical method for synthesizing and
comparing observed and modelled data across a range of spatio-temporal
scales. Instead of focusing at specific scales, such as annual means or
original grid resolution, we examine how their statistical properties
change across spatio-temporal continuum.
